The Wasabi component provides an easy way to interface with the Wasabi service.

Syntax

TcsWasabi

Remarks

Wasabi has an API that is fully compatible with that of Amazon S3, allowing you to store arbitrary data using the same bucket-and-object paradigm that S3 uses. Wasabi adds additional functionality on top of the S3 API. Whether you're doing simple bucket-and-object data manipulation, or leveraging Wasabi-exclusive API features, the Wasabi component makes it easy to access the Wasabi service quickly and securely.

Wasabi's API additions range in scale; the simplest example is the ability to rename buckets, objects, and folders. The most notable API additions, however, are two full-blown headline features: Composition and Compliance. Composition allows you to concatenate (or, "compose") together objects which are already on the server; it's a simpler, cheaper, and more flexible alternative to S3's multipart uploads. The Compliance system gives you the ability to define policies that dictate how long objects must be retained before they can be modified or deleted. We recommend referring to Wasabi's website for more details about these features.

To use the Wasabi component, you will first need to sign up for the Wasabi service and obtain an AccessKey and a SecretKey. Then you can start creating buckets in your account using CreateBucket. The buckets are place holders for your objects allowing you to access them by http URLs. You can then add objects to any of your buckets using CreateObject.

The ComposeObjects and UpdateCompliance methods' documentation provide extensive usage details and examples for composition and compliance; the RenameBucket, RenameObject, and RenameFolder methods speak for themselves; and the standard bucket-and-object manipulation features are available through methods such as ListBuckets, ListObjects, GetObject, DeleteObject, GetLink, and more.

Remarks

This property contains the name of the local host as obtained by the gethostname() system call, or if the user has assigned an IP address, the value of that address.

In multihomed hosts (machines with more than one IP interface) setting LocalHost to the IP address of an interface will make the component initiate connections (or accept in the case of server components) only through that interface. It is recommended to provide an IP address rather than a hostname when setting this property to ensure the desired interface is used.

If the component is connected, the LocalHost property shows the IP address of the interface through which the connection is made in internet dotted format (aaa.bbb.ccc.ddd). In most cases, this is the address of the local host, except for multihomed hosts (machines with more than one IP interface).

Note: LocalHost is not persistent. You must always set it in code, and never in the property window.

Remarks

If this property is non-empty when ListObjects or ListVersions is called, any objects (or object versions) whose names contain the same string between the specified ObjectPrefix and the first occurrence of the specified delimiter that follow will be rolled up into a "common prefix" element, which is returned in place of the individual objects themselves.

The PrefixList event will fire once for each common prefix returned. If the StorePrefixList configuration setting is enabled, the component will also populate the PrefixCount and Prefix[i] configuration settings

Object Hierarchy Traversal

By using the ObjectDelimiter and ObjectPrefix properties in tandem, applications can effectively "traverse" a virtual hierarchy of objects (or object versions) as if it were a filesystem. For example, assume that objects with the following names exist within a bucket:

• MyCompany/
• MyCompany/Department1/
• MyCompany/Department2/
• MyCompany/Department2/EmployeeA
• MyCompany/Department2/EmployeeB

With ObjectDelimiter set to /, we can set ObjectPrefix to successively "deeper" values before calling ListObjects or ListVersions for the following effect:

This property is read-only.

Data Type

String

SSLServerCertSubject Property (Wasabi Component)

The subject of the certificate used for client authentication.

Syntax

__property String SSLServerCertSubject = { read=FSSLServerCertSubject };

Default Value

""

Remarks

The subject of the certificate used for client authentication.

This property must be set after all other certificate properties are set. When this property is set, a search is performed in the current certificate store to locate a certificate with a matching subject.

If a matching certificate is found, the property is set to the full subject of the matching certificate.

If an exact match is not found, the store is searched for subjects containing the value of the property.

If a match is still not found, the property is set to an empty string, and no certificate is selected.

The special value "*" picks a random certificate in the certificate store.

The certificate subject is a comma-separated list of distinguished name fields and values. For instance, "CN=www.server.com, OU=test, C=US, E=support@nsoftware.com". Common fields and their meanings are as follows:

If a field value contains a comma, it must be quoted.

This property is read-only.

Data Type

String

SSLServerCertEncoded Property (Wasabi Component)

The certificate (PEM/Base64 encoded).

Syntax

__property String SSLServerCertEncoded = { read=FSSLServerCertEncoded };
__property DynamicArray<Byte> SSLServerCertEncodedB = { read=FSSLServerCertEncodedB };

Default Value

""

Remarks

The certificate (PEM/Base64 encoded). This property is used to assign a specific certificate. The SSLServerCertStore and SSLServerCertSubject properties also may be used to specify a certificate.

When SSLServerCertEncoded is set, a search is initiated in the current SSLServerCertStore for the private key of the certificate. If the key is found, SSLServerCertSubject is updated to reflect the full subject of the selected certificate; otherwise, SSLServerCertSubject is set to an empty string.

This property is read-only and not available at design time.

Data Type

Byte Array

StartByte Property (Wasabi Component)

The byte offset from which to resume the upload or download.

Syntax

__property __int64 StartByte = { read=FStartByte, write=FSetStartByte };

Default Value

0

Remarks

This property specifies the byte offset from which to resume an automatic multipart upload initiated by CreateObject, or a download initiated by GetObject. Refer to those methods' documentation for more information about resuming uploads and downloads.

This property is not available at design time.

Data Type

Long64

Timeout Property (Wasabi Component)

The timeout for the component.

Syntax

__property int Timeout = { read=FTimeout, write=FSetTimeout };

Default Value

60

Remarks

If the Timeout property is set to 0, all operations will run uninterrupted until successful completion or an error condition is encountered.

If Timeout is set to a positive value, the component will wait for the operation to complete before returning control.

The component will use DoEvents to enter an efficient wait loop during any potential waiting period, making sure that all system events are processed immediately as they arrive. This ensures that the host application does not freeze and remains responsive.

If Timeout expires, and the operation is not yet complete, the component raises an exception.

Note: By default, all timeouts are inactivity timeouts, that is, the timeout period is extended by Timeout seconds when any amount of data is successfully sent or received.

The default value for the Timeout property is 60 seconds.

Data Type

Integer

UseSSL Property (Wasabi Component)

Whether to use SSL/TLS when connecting.

Syntax

__property bool UseSSL = { read=FUseSSL, write=FSetUseSSL };

Default Value

true

Remarks

This property specifies whether the component should use SSL/TLS when connecting.

This property is not available at design time.

Data Type

Boolean

UseVirtualHosting Property (Wasabi Component)

Determines which style request to use.

Syntax

__property bool UseVirtualHosting = { read=FUseVirtualHosting, write=FSetUseVirtualHosting };

Default Value

True

Remarks

If set to true (default), buckets will be referenced in the request using the hosted-style request: http://yourbucket.s3.wasabisys.com/yourobject. If false, the component will use the path-style request: http://s3.wasabisys.com/yourbucket/yourobject.

NOTE: When set to true, there are more limitations when choosing a bucket name due to DNS server naming restrictions. Wasabi follows Amazon's naming restrictions, so refer to Amazon's S3 documentation for more information.

This property is not available at design time.

Data Type

Boolean

VersionId Property (Wasabi Component)

The object version to make requests against.

Syntax

__property String VersionId = { read=FVersionId, write=FSetVersionId };

Default Value

""

Remarks

This property can be set to the Id of a specific object version before calling the following methods in order to make requests against the specified object version instead of the base object; refer to each one's documentation for more information:

• CopyObject (to copy from a specific object version)
• DeleteObject
• GetLink (to build a link for a specific object version)
• GetObject
• GetObjectInfo
• SendCustomRequest
• UpdateObjectACL

Refer to Amazon's Versioning documentation for more information about versioning.

This property is not available at design time.

Data Type

String

VersionMarker Property (Wasabi Component)

A marker indicating what page of object versions to return next.

Syntax

__property String VersionMarker = { read=FVersionMarker, write=FSetVersionMarker };

Default Value

""

Remarks

This property will be populated when ListVersions is called if the results are paged and there are more pages. To list all object versions, continue to call ListVersions until this property returns empty string.

Refer to ListVersions for more information.

This property is not available at design time.

Data Type

String

AbortMultipartUpload Method (Wasabi Component)

Aborts a multipart upload.

Syntax

void __fastcall AbortMultipartUpload(String ObjectName, String UploadId);

Remarks

This method aborts the multipart upload of the object named ObjectName specified by UploadId.

When this method is called, all parts that have been uploaded for the multipart upload are deleted from the server. (Note that if any part uploads are currently in progress, it may be necessary to call this method again after they complete.)

If this method is called successfully, the specified UploadId will no longer be valid.

AddMetadata Method (Wasabi Component)

Adds a metadata item to the Metadata properties.

Syntax

void __fastcall AddMetadata(String Name, String Value);

Remarks

This method adds a metadata item to the Metadata properties. Name specifies the name of the item, and Value specifies the value of the item. Keep in mind that the server stores metadata names in lowercase.

If Name begins with a service-specific metadata (e.g., x-amz-meta-, x-goog-meta-, etc.), it will be stripped off. The component will take care of prepending it when sending metadata to the server.

AddQueryParam Method (Wasabi Component)

Adds a query parameter to the QueryParams properties.

Syntax

void __fastcall AddQueryParam(String Name, String Value);

Remarks

This method is used to add a query parameter to the QueryParams properties. Name specifies the name of the parameter, and Value specifies the value of the parameter.

All specified Values will be URL encoded by the component automatically. Consult the service documentation for details on the available parameters.

AppendObject Method (Wasabi Component)

Appends data onto an object on the server.

Syntax

void __fastcall AppendObject(String ObjectName);

Remarks

This method will append the content of the file specified by LocalFile into the bucket specified by the Bucket property. If LocalFile is empty, the contents of the ObjectData property will be uploaded instead.

You may only append to an object that already exists. To create a new object, use the CreateObject method.

Note: Appending is a form of object composition, so the same restrictions that apply for object composition also apply when appending to objects; refer to ComposeObjects for more information.

BucketExists Method (Wasabi Component)

Checks whether the bucket exists.

Syntax

bool __fastcall BucketExists();

Remarks

This method checks whether the bucket specified by Bucket exists, returning true if so or false if not.

CheckVersioningEnabled Method (Wasabi Component)

Checks whether versioning is enabled for the currently selected bucket.

Syntax

bool __fastcall CheckVersioningEnabled();

Remarks

This method can be used to check whether the bucket currently selected by Bucket has versioning enabled.

Note that if Bucket is empty, or refers to a bucket that does not exist, this method will always return false when queried.

Refer to Amazon's Versioning documentation for more information about versioning.

CompleteMultipartUpload Method (Wasabi Component)

Completes a multipart upload by assembling previously uploaded parts.

Syntax

void __fastcall CompleteMultipartUpload(String ObjectName, String UploadId);

Remarks

This method completes the multipart upload specified by UploadId. The server will assemble all of the parts that have been uploaded into an object named ObjectName.

Note that this method automatically calls ListParts internally to obtain the information needed to complete the multipart upload. This process does not alter the Parts properties, nor does it cause the PartList event to fire.

ComposeObjects Method (Wasabi Component)

Creates a composed object using multiple objects already on the server.

Syntax

void __fastcall ComposeObjects(String ComposedObjectName);

Remarks

This method is used to compose objects on the server. Object composition is a server-side method of building an object by concatenating multiple existing objects together. This feature is a simpler alternative to the typical multipart-upload method of building objects.

A composed object looks and acts just like a regular object. However, its data is determined by its component objects (that is, the objects that make it up) and the order in which they are composed together.

To use this method, specify the names of the objects that should be composed together using the Objects property. When this method is called, the ComposedObjectName parameter determines what name is given to the resulting composed object. See the following code snippet for examples: // Upload some objects to start with. Let's assume we have some text files to upload. for (int i = 1; i <= 3; i++) { wasabi.LocalFile = "file" + i + ".txt"; wasabi.CreateObject("file" + i + ".txt"); } // Compose a new object. SetObjectNames("file1.txt", "file2.txt", "file3.txt"); wasabi.ComposeObjects("composed1.txt"); // Compose a new object using a composed object. SetObjectNames("file1.txt", "composed1.txt"); wasabi.ComposeObjects("composed2.txt"); // Compose onto an existing composed object. // (Similar to appending, but all server-side, no uploading needed.) SetObjectNames("file1.txt", "file2.txt"); wasabi.ComposeObjects("composed3.txt"); SetObjectNames("composed3.txt", "file3.txt"); wasabi.ComposeObjects("composed3.txt"); // Compose a new object using the same object twice. SetObjectNames("file1.txt", "file1.txt"); wasabi.ComposeObjects("composed4.txt"); // Compose a composed object onto itself. SetObjectNames("composed4.txt", "composed4.txt"); wasabi.ComposeObjects("composed4.txt"); Assume we have this helper method for the above code: void SetObjectNames(params string[] names) { wasabi.Objects.Clear(); foreach (string name in names) wasabi.Objects.Add(new S3Object(name, "", 0, "", "", "", "", "")); }

Object composition is a powerful and flexible feature. However, there are some things to keep in mind when doing object composition:

• The order of the object names in the Objects property is the order that they will be concatenated in when they are composed.
• Objects from multiple buckets cannot be composed together.
• No more than 32 object names may be specified in a single compose request.
• No more than 1024 original objects may be composed together. This is a transitive limit, it cannot be circumvented by composing together composed objects.

Wasabi does not make copies of data when composing objects, it uses references, so there are no extra data charges. Even if the original objects are deleted, a single copy of the data is kept until there are no longer any composed objects which reference it. Refer to the Wasabi documentation for more information.

Config Method (Wasabi Component)

Sets or retrieves a configuration setting.

Syntax

String __fastcall Config(String ConfigurationString);

Remarks

Config is a generic method available in every component. It is used to set and retrieve configuration settings for the component.

These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the component, access to these internal properties is provided through the Config method.

To set a configuration setting named PROPERTY, you must call Config("PROPERTY=VALUE"), where VALUE is the value of the setting expressed as a string. For boolean values, use the strings "True", "False", "0", "1", "Yes", or "No" (case does not matter).

To read (query) the value of a configuration setting, you must call Config("PROPERTY"). The value will be returned as a string.

CopyObject Method (Wasabi Component)

Copies an object.

Syntax

void __fastcall CopyObject(String SrcObjectName, String DestBucket, String DestObjectName);

Remarks

This method copies the object specified by SrcObjectName (in the bucket currently selected by Bucket) to the object specified by DestObjectName in DestBucket. If DestBucket is empty, the bucket specified by Bucket is used as the destination bucket.

If the VersionId property is non-empty, the specified version of the source object will be used as the copy source. In this case, DestObjectName may be the same as SrcObjectName to "promote" the version, copying its contents back to the base object.

If there are any metadata items present in the Metadata properties, they will set on the destination object; otherwise, the server will copy any metadata items present on the source object to the destination object.

Notes:

• Objects may only be copied to buckets that exist within the same region.
• Objects larger than 5GB cannot be copied using this method. To copy such objects, start a new multipart upload for the destination object using StartMultipartUpload, and then use the CopyPart method to create parts for said multipart upload using the source object's data.

CopyPart Method (Wasabi Component)

Copies the specified object as a part of a multipart upload.

Syntax

void __fastcall CopyPart(String SrcObjectName, String DestBucket, String DestObjectName, int DestPartNumber, String DestUploadId);

Remarks

This method copies data from the object specified by SrcObjectName (in the bucket currently selected by Bucket) to a new multipart upload part for DestObjectName in DestBucket.

The DestPartNumber and DestUploadId parameters should be used in the same manner as the UploadPart method's PartNumber and UploadId parameters.

To copy a specific range of bytes from the source object, set the CopyPartRange configuration setting before calling this method.

CreateBucket Method (Wasabi Component)

Creates a new bucket.

Syntax

void __fastcall CreateBucket();

Remarks

This method creates a new bucket using the name specified by the Bucket property. The bucket is created in the region specified by the Region property.

CreateObject Method (Wasabi Component)

Creates a new object in the currently selected bucket.

Syntax

void __fastcall CreateObject(String ObjectName);

Remarks

This method creates a new object named Object in the bucket currently selected by Bucket. If there are any metadata items present in the Metadata properties, they will included in the creation request.

If LocalFile is set the file will be uploaded from the specified path. If LocalFile is not set the data in ObjectData will be used.

To encrypt the file before uploading it, set EncryptionAlgorithm and EncryptionPassword.

This method can automatically handle the multipart upload of objects (See Below). If it is desired to manually take control of the multipart upload process see StartMultipartUpload.

Automatic Multipart Uploads

If more than SimpleUploadLimit bytes of data are provided, the component will automatically perform a multipart upload by splitting the data up into parts (sized according to the FragmentSize configuration setting) and uploading them individually. To accomplish this, the component automatically makes calls to StartMultipartUpload, UploadPart, and CompleteMultipartUpload internally; tracks upload state information using the ResumableUploadState configuration setting; and tracks how much data has been uploaded using the StartByte property. The FragmentComplete event will fire after each part is uploaded.

If, during an automatic multipart upload, any individual request fails, the upload can be resumed be calling this method again with the same parameters, so long as ResumableUploadState and StartByte contain the same values as they did when the upload was interrupted.

When an automatic multipart upload completes successfully, ResumableUploadState is cleared and StartByte is reset to 0.

DeleteBucket Method (Wasabi Component)

Deletes a bucket.

Syntax

void __fastcall DeleteBucket();

Remarks

This method deletes the bucket currently selected by Bucket. Note that bucket names share a global namespace, and it may not be possible to recreate a deleted bucket if its name has been taken by another user in the meantime.

DeleteObject Method (Wasabi Component)

Deletes an object.

Syntax

void __fastcall DeleteObject(String ObjectName);

Remarks

This method deletes the object specified by ObjectName in the bucket currently selected by Bucket.

If the VersionId property is non-empty, this method deletes the specified version of the object instead.

Deleting Versioned Objects

If an object's latest version is a delete marker, then the server treats the object as if it didn't exist (i.e., it doesn't appear when listing objects, cannot be downloaded, etc.). However, all of the previous versions of the object (including one that existed just before the delete marker was created) still exist; they can be listed using ListVersions, and explicitly interacted with by setting VersionId and calling an appropriate method.

To permanently delete objects in a versioning-enabled bucket, each version of the object must be explicitly deleted by setting VersionId before calling this method. This includes any delete marker versions, which can be deleted like any other version.

Refer to Amazon's Deleting Object Versions, Working with Delete Markers, and Removing Delete Markers articles for more information.

DisableVersioning Method (Wasabi Component)

Disables versioning for the currently selected bucket.

Syntax

void __fastcall DisableVersioning();

Remarks

This method can be used to disable versioning for the bucket currently selected by Bucket.

Refer to Amazon's Versioning documentation for more information about versioning.

DoEvents Method (Wasabi Component)

This method processes events from the internal message queue.

Syntax

void __fastcall DoEvents();

Remarks

When DoEvents is called, the component processes any available events. If no events are available, it waits for a preset period of time, and then returns.

EnableVersioning Method (Wasabi Component)

Enables versioning for the currently selected bucket.

Syntax

void __fastcall EnableVersioning();

Remarks

This method can be used to enable versioning for the bucket currently selected by Bucket.

Refer to Amazon's Versioning documentation for more information about versioning.

GetBucketLocation Method (Wasabi Component)

Gets a bucket's location.

Syntax

String __fastcall GetBucketLocation();

Remarks

This method retrieves and returns the location (i.e., region) of the bucket currently selected by Bucket.

GetCompliance Method (Wasabi Component)

Gets the compliance settings for the current bucket or an object in it.

Syntax

void __fastcall GetCompliance(String ObjectName);

Remarks

Calling this method and passing the empty string for ObjectName will cause BucketCompliance to be populated for the current bucket. Otherwise, this method will cause ObjectCompliance to be populated for the object with the given ObjectName (as long as such an object exists in the current bucket, and the bucket's compliance settings are enabled).

Refer to the UpdateCompliance documentation for more information about compliance.

GetLink Method (Wasabi Component)

Creates a link that provides access to an object for a specified amount of time.

Syntax

String __fastcall GetLink(String ObjectName, int Expires);

Remarks

This method creates and returns a pre-authenticated link that provides access to the object specified by ObjectName in the bucket currently selected by Bucket. If the VersionId property is non-empty, a link is created for the specified version of the object.

The Expires parameter specifies how many seconds the link should be valid for. The maximum validity period is seven days.

Note that this method is an offline method that simply generates a pre-signed URL; no communication with the server takes place.

GetObject Method (Wasabi Component)

Downloads an object.

Syntax

void __fastcall GetObject(String ObjectName);

Remarks

This methods downloads the object specified by ObjectName in the bucket currently selected by Bucket. If the VersionId property is non-empty, the specified version of the object is downloaded instead. The Range property can be used to download a specific range of bytes from the object.

If LocalFile is set, the object data will be saved to the specified location; otherwise, the object data will be held by ObjectData.

To download and decrypt an encrypted object, set EncryptionAlgorithm and EncryptionPassword before calling this method.

Download Notes

In the simplest use-case, downloading an object looks like this: s3.LocalFile = "../MyData.zip"; s3.GetObject(s3.Objects[0].Name);

Resuming Downloads

The component also supports resuming failed downloads by using the StartByte property. If a download is interrupted, set StartByte to the appropriate offset before calling this method to resume the download. string downloadFile = "../MyData.zip"; s3.LocalFile = downloadFile; s3.GetObject(s3.Objects[0].Name); //The transfer is interrupted and GetObject() above fails. Later, resume the download: //Get the size of the partially downloaded file s3.StartByte = new FileInfo(downloadFile).Length; s3.GetObject(s3.Objects[0].Name);

Resuming Encrypted File Downloads

Resuming encrypted file downloads is only supported when LocalFile was set in the initial download attempt.

If LocalFile is set when beginning an encrypted download, the component creates a temporary file in TempPath to hold the encrypted data until the download is complete. If the download is interrupted, DownloadTempFile will be populated with the path of the temporary file that holds the partial data.

To resume, DownloadTempFile must be populated, along with StartByte, to allow the remainder of the encrypted data to be downloaded. Once the encrypted data is downloaded it will be decrypted and written to LocalFile. s3.LocalFile = "../MyData.zip"; s3.EncryptionPassword = "password"; s3.GetObject(s3.Objects[0].Name); //The transfer is interrupted and GetObject() above fails. Later, resume the download: //Get the size of the partially downloaded temp file s3.StartByte = new FileInfo(s3.Config("DownloadTempFile")).Length; s3.GetObject(s3.Objects[0].Name);

GetObjectInfo Method (Wasabi Component)

Gets an object's information and metadata.

Syntax

void __fastcall GetObjectInfo(String ObjectName);

Remarks

This method gets information and metadata for the object specified by Object in the bucket currently selected by Bucket. If the VersionId property is non-empty, information and metadata for the specified version of the object is retrieved instead.

Calling this method will fire the ObjectList and MetadataList events, and will re-populate the Objects and Metadata collection properties.

Interrupt Method (Wasabi Component)

This method interrupts the current method.

Syntax

void __fastcall Interrupt();

Remarks

If there is no method in progress, Interrupt simply returns, doing nothing.

ListBuckets Method (Wasabi Component)

Lists all buckets in the account.

Syntax

void __fastcall ListBuckets();

Remarks

This method lists all buckets in the account.

Calling this method will fire the BucketList event once for each bucket, and will also populate the Buckets properties.

ListMultipartUploads Method (Wasabi Component)

Lists the current multipart uploads.

Syntax

void __fastcall ListMultipartUploads();

Remarks

This method lists the current multipart uploads in the bucket currently selected by Bucket.

Before calling this method, the ObjectPrefix property may be set in order to restrict the results to only the multipart uploads whose names begin with a given string. The ObjectDelimiter property can also be used to further tune the results returned. The MaxObjects configuration setting may be used to limit the number of results returned.

Calling this method will fire the ObjectList event once for each multipart upload, and will also populate the Objects properties.

If there are still more multipart uploads available to list when this method returns, the ObjectMarker property will be populated. Continue to call this method until ObjectMarker is empty to accumulate all pages of results in the Objects properties. Alternatively, the AccumulatePages configuration setting can be disabled to clear the Objects properties every time a page of results is returned.

ListObjects Method (Wasabi Component)

Lists the objects in a bucket.

Syntax

void __fastcall ListObjects();

Remarks

This method lists the objects in the bucket currently selected by Bucket.

Before calling this method, the ObjectPrefix property may be set in order to restrict the results to only the objects whose names begin with a given string. The ObjectDelimiter property can also be used to further tune the results returned. The MaxObjects configuration setting may be used to limit the number of results returned.

Calling this method will fire the ObjectList event once for each object, and will also populate the Objects properties. It may also fire the PrefixList event, and populate the PrefixCount and Prefix[i] configuration settings, depending on how the properties discussed above are set.

If there are still more objects available to list when this method returns, the ObjectMarker property will be populated. Continue to call this method until ObjectMarker is empty to accumulate all pages of results in the Objects properties. Alternatively, the AccumulatePages configuration setting can be disabled to clear the Objects properties every time a page of results is returned.

Object Hierarchy Traversal

By using the ObjectDelimiter and ObjectPrefix properties in tandem, applications can effectively "traverse" a virtual hierarchy of objects (or object versions) as if it were a filesystem. For example, assume that objects with the following names exist within a bucket:

• MyCompany/
• MyCompany/Department1/
• MyCompany/Department2/
• MyCompany/Department2/EmployeeA
• MyCompany/Department2/EmployeeB

With ObjectDelimiter set to /, we can set ObjectPrefix to successively "deeper" values before calling ListObjects or ListVersions for the following effect:

ListParts Method (Wasabi Component)

Lists the parts in a multipart upload.

Syntax

void __fastcall ListParts(String ObjectName, String UploadId);

Remarks

This method lists the parts in the multipart upload of ObjectName specified by UploadId. The MaxParts configuration setting may be used to limit the number of results returned.

Calling this method will fire the PartList event once for each part, and will also populate the Parts properties.

If there are still more parts available to list when this method returns, the PartMarker property will be populated. Continue to call this method until PartMarker is empty to accumulate all pages of results in the Parts properties. Alternatively, the AccumulatePages configuration setting can be disabled to clear the Parts properties every time a page of results is returned.

Note that this method does not need to be called before attempting to complete a multipart upload with CompleteMultipartUpload; the component will automatically collect the necessary information internally. Refer to CompleteMultipartUpload for more information.

ListVersions Method (Wasabi Component)

Lists the object versions in a bucket.

Syntax

void __fastcall ListVersions();

Remarks

This method lists the object versions in the bucket currently selected by Bucket.

Before calling this method, the ObjectPrefix property may be set in order to restrict the results to only the object versions whose names begin with a given string. The ObjectDelimiter property can also be used to further tune the results returned. The MaxObjects configuration setting may be used to limit the number of results returned.

Calling this method will fire the ObjectList event once for each object version, and will also populate the Objects properties. It may also fire the PrefixList event, and populate the PrefixCount and Prefix[i] configuration settings, depending on how the properties discussed above are set.

If there are still more object versions available to list when this method returns, the VersionMarker property will be populated. Continue to call this method until VersionMarker is empty to accumulate all pages of results in the Objects properties. Alternatively, the AccumulatePages configuration setting can be disabled to clear the Objects properties every time a page of results is returned.

Object Hierarchy Traversal

By using the ObjectDelimiter and ObjectPrefix properties in tandem, applications can effectively "traverse" a virtual hierarchy of objects (or object versions) as if it were a filesystem. For example, assume that objects with the following names exist within a bucket:

• MyCompany/
• MyCompany/Department1/
• MyCompany/Department2/
• MyCompany/Department2/EmployeeA
• MyCompany/Department2/EmployeeB

With ObjectDelimiter set to /, we can set ObjectPrefix to successively "deeper" values before calling ListObjects or ListVersions for the following effect:

RenameBucket Method (Wasabi Component)

Renames a bucket.

Syntax

void __fastcall RenameBucket(String BucketName, String NewName);

Remarks

This method renames the bucket named BucketName to the name NewName. NewName cannot already be in use by another bucket.

RenameFolder Method (Wasabi Component)

Renames a folder.

Syntax

void __fastcall RenameFolder(String FolderName, String NewName);

Remarks

This method renames the folder named FolderName to the name NewName. If NewName is already in use by existing folders, it will be overwritten if the current bucket has versioning enabled, or if the OverwriteOnRename configuration setting is set to true (default).

Since "folders" are in fact just name prefixes formatted to mimic a traditional file system, this method can rename multiple levels of "folders" at once by renaming a prefix. For example, assume you have the following objects in a bucket:

• /pictures/animals/cats/cat1.jpg
• /pictures/animals/cats/cat2.jpg
• /pictures/animals/cats/cat3.jpg
• /pictures/animals/cats/cat4.jpg
• /pictures/animals/dogs/dog4.jpg
• /pictures/animals/dogs/dog5.jpg

Doing the following command would leave you with the following objects in the bucket:

wasabi.RenameFolder("/pictures/animals/cats/", "pictures/pets/dogs");

• /pictures/pets/dogs/cat1.jpg
• /pictures/pets/dogs/cat2.jpg
• /pictures/pets/dogs/cat3.jpg
• /pictures/pets/dogs/cat4.jpg
• /pictures/pets/dogs/dog4.jpg
• /pictures/pets/dogs/dog5.jpg

And doing this command instead would leave you with these objects in the bucket, since the prefix being renamed now includes part of the "filename", and since (by default) the original "dog4.jpg" will get overwritten when "cat4.jpg" is renamed:

RenameObject Method (Wasabi Component)

Renames an object.

Syntax

void __fastcall RenameObject(String ObjectName, String NewName);

Remarks

This method renames the object named ObjectName to the name NewName. If NewName is already in use by an existing object, it will be overwritten if the current bucket has versioning enabled, or if the OverwriteOnRename configuration setting is set to true (default).

Reset Method (Wasabi Component)

Resets the component to its initial state.

Syntax

void __fastcall Reset();

Remarks

This method resets the component to its initial state.

ResetHeaders Method (Wasabi Component)

Resets all HTTP headers, cookies, and LocalFile.

Syntax

void __fastcall ResetHeaders();

Remarks

Resets all the HTTP headers as well as LocalFile to "" (empty string), and clears the Metadata and QueryParams collection properties.

Call this method before creating a new request, so that headers and query parameters from the previous request are not carried over to the next one.

SendCustomRequest Method (Wasabi Component)

Sends a custom request to the server.

Syntax

void __fastcall SendCustomRequest(String HttpMethod, String ObjectName, String RequestBody);

Remarks

This method can be used to send arbitrary requests to the server.

Valid values for HttpMethod are:

• GET (default if empty)
• HEAD
• POST
• PUT
• DELETE

The ObjectName and RequestBody parameters may be empty if not needed.

Usage

When this method is called, the component does the following:

1. Builds a request URL, including query parameters, based on the following:
   • UseSSL, Region, and UseVirtualHosting for the base URL.
     • Alternatively, if a custom URL has been specified using the URL configuration setting, it is used directly, and these properties are ignored.
   • Bucket (if non-empty)
   • ObjectName (if non-empty)
   • VersionId (if both it and ObjectName are non-empty)
   • QueryParams
2. Adds request headers from:
   • ContentDisposition
   • ContentType
   • OtherHeaders
   • ProductToken
   • SessionToken
   • UserToken
3. Signs the request (unless the SignCustomRequest configuration setting is disabled).
4. Sends the request, including RequestBody if non-empty.
5. Stores the response headers in the ParsedHeaders properties; and the response body in the specified LocalFile, or ObjectData (using the same logic as GetObject).

If the response body is XML data, the XPath, XText, and other X* configuration settings can then be used to navigate and extract information from it.

StartMultipartUpload Method (Wasabi Component)

Starts a new manual multipart upload.

Syntax

String __fastcall StartMultipartUpload(String ObjectName);

Remarks

This method starts a new "manual" multipart upload for an object named ObjectName, in the bucket currently selected by Bucket, and returns the upload Id that the server associates with it. For an "automatic" multipart upload see the CreateObject method. This upload Id can then be used to call the following methods:

• UploadPart
• CopyPart
• ListParts
• CompleteMultipartUpload
• AbortMultipartUpload

If there are any metadata items present in the Metadata properties, they will be included in the creation request, and will be applied to the final object after the multipart upload is completed with CompleteMultipartUpload.

Multipart uploads never expire, they must be explicitly completed or aborted using CompleteMultipartUpload or AbortMultipartUpload. The ListMultipartUploads method can be used to retrieve a list of current multipart uploads.

UpdateBucketACL Method (Wasabi Component)

Updates a bucket's canned access policy.

Syntax

void __fastcall UpdateBucketACL();

Remarks

This method updates the canned access policy of the bucket selected by Bucket to the value specified by AccessPolicy

UpdateCompliance Method (Wasabi Component)

Updates the compliance settings for the current bucket or an object in it.

Syntax

void __fastcall UpdateCompliance(String ObjectName);

Remarks

Calling this method and passing the empty string for ObjectName will cause the compliance settings stored in BucketCompliance to be applied to the current bucket. Otherwise, this method will cause the compliance settings stored in ObjectCompliance to be applied to the object with the given ObjectName (as long as such an object exists in the current bucket, and the bucket's compliance settings are enabled).

Compliance Notes

Compliance is a Wasabi feature that prevents objects from being modified or deleted before a specified time. The following tables and examples show what compliance settings are available at the bucket- and object-levels, what they do, and how they are used. Be sure to review the documentation for each of the individual settings for more information about them.

Bucket Compliance Settings

Compliance starts at the bucket level, it must be turned on for a bucket in order for the objects within that bucket to be under compliance. The component makes this easy to do: wasabi.Bucket = "MyBucket"; wasabi.BucketCompliance = new WasabiBucketCompliance("enabled", "", 10, "true", ""); wasabi.UpdateCompliance(""); This code turns on compliance settings for the bucket called "MyBucket", setting them so that objects are placed under conditional hold, and must be retained for 10 days after the conditional hold is released. The LockTime and DeleteAfterRetention settings are left alone, so they will default to "off" and "false" (respectively).

Important: Locking the compliance settings on a bucket using the LockTime setting is a one-way action. You cannot unlock a bucket's compliance settings without contacting the Wasabi support team. Refer to the Wasabi documentation for more information.

Object Compliance Settings

When an object's bucket has compliance enabled, all objects in that bucket are under compliance, and you can query any object's compliance settings using the GetCompliance method.

Any individual object can have its compliance settings updated as well. The LegalHold setting can be toggled to prevent (or allow) deletion; the object's ConditionalHold, if "true", can be released by setting to "false", at which time the object will begin its retention period. The object's RetentionTime can also be extended (but not reduced). For example, if you wanted to release an object from conditional hold: wasabi.Bucket = "MyBucket"; wasabi.ObjectCompliance = new WasabiObjectCompliance("", "false", ""); wasabi.UpdateCompliance("MyObject");

Further Information

Compliance is a powerful tool, but it must be handled carefully. These notes, and the documentation for the compliance-related properties, methods, and types, do not supersede Wasabi's documentation, and reviewing that documentation is highly recommended to gain a full understanding of how compliance works.

UpdateObjectACL Method (Wasabi Component)

Updates an object's canned access policy.

Syntax

void __fastcall UpdateObjectACL(String ObjectName);

Remarks

This method updates the caned access policy of the objects specified by ObjectName, in the bucket currently selected by Bucket, to the value specified by AccessPolicy.

If the VersionId property is non-empty, the canned access policy of the specified version of the object is updated instead.

UploadPart Method (Wasabi Component)

Uploads a multipart upload part.

Syntax

void __fastcall UploadPart(String ObjectName, int PartNumber, String UploadId);

Remarks

This method uploads a part for the multipart upload of the object named ObjectName specified by UploadId.

PartNumber specifies the part's number; it must be a value in the range 1 to 10000, inclusive. If a part with the given number already exists in the specified multipart upload, it is replaced with the newly-uploaded part.

The data to upload is taken from either LocalFile or ObjectData (whichever data is found in first, when checked in that order). Each part must be at least 5MB in size, except for the last part in the overall multipart upload, which can be any non-zero size.

If the IncludePartMD5 configuration setting is true, the component will include an MD5 digest of its data when sending it to the server. The server will then verify that the data was received without corruption.

BucketList Event (Wasabi Component)

Fires once for each bucket returned when listing buckets.

Syntax

typedef struct {
  String BucketName;
  String CreationDate;
  String OwnerId;
  String OwnerName;
} TcsWasabiBucketListEventParams;
typedef void __fastcall (__closure *TcsWasabiBucketListEvent)(System::TObject* Sender, TcsWasabiBucketListEventParams *e);
__property TcsWasabiBucketListEvent OnBucketList = { read=FOnBucketList, write=FOnBucketList };

Remarks

This event fires once for each bucket returned when ListBuckets is called.

BucketName reflects the name of the bucket.

CreationDate reflects the bucket's creation date.

OwnerId and OwnerName reflect the Id and display name of the bucket's owner, respectively.

EndTransfer Event (Wasabi Component)

This event fires when a document finishes transferring.

Syntax

typedef struct {
  int Direction;
} TcsWasabiEndTransferEventParams;
typedef void __fastcall (__closure *TcsWasabiEndTransferEvent)(System::TObject* Sender, TcsWasabiEndTransferEventParams *e);
__property TcsWasabiEndTransferEvent OnEndTransfer = { read=FOnEndTransfer, write=FOnEndTransfer };

Remarks

The EndTransfer event is fired when the document text finishes transferring from the server to the local host.

The Direction parameter shows whether the client (0) or the server (1) is sending the data.

Error Event (Wasabi Component)

Fired when information is available about errors during data delivery.

Syntax

typedef struct {
  int ErrorCode;
  String Description;
} TcsWasabiErrorEventParams;
typedef void __fastcall (__closure *TcsWasabiErrorEvent)(System::TObject* Sender, TcsWasabiErrorEventParams *e);
__property TcsWasabiErrorEvent OnError = { read=FOnError, write=FOnError };

Remarks

The Error event is fired in case of exceptional conditions during message processing. Normally the component raises an exception.

The ErrorCode parameter contains an error code, and the Description parameter contains a textual description of the error. For a list of valid error codes and their descriptions, please refer to the Error Codes section.

FragmentComplete Event (Wasabi Component)

Fires after each part in an automatic multipart upload is complete.

Syntax

typedef struct {
  int FragmentNumber;
  int FragmentCount;
  bool Interrupt;
} TcsWasabiFragmentCompleteEventParams;
typedef void __fastcall (__closure *TcsWasabiFragmentCompleteEvent)(System::TObject* Sender, TcsWasabiFragmentCompleteEventParams *e);
__property TcsWasabiFragmentCompleteEvent OnFragmentComplete = { read=FOnFragmentComplete, write=FOnFragmentComplete };

Remarks

If, when CreateObject is called, more than SimpleUploadLimit bytes of upload data are present, the component will automatically split the upload data up into parts and perform a multipart upload. During the overall upload process, this event will fire after each part is uploaded, providing an indication of overall upload progress.

FragmentNumber is the number of the current part that has completed. This value starts at 1.

FragmentCount is the total number of parts that will be uploaded.

Interrupt can be set to true to interrupt the upload. The upload may be resumed later.

Refer to CreateObject for more information.

Header Event (Wasabi Component)

Fired every time a header line comes in.

Syntax

typedef struct {
  String Field;
  String Value;
} TcsWasabiHeaderEventParams;
typedef void __fastcall (__closure *TcsWasabiHeaderEvent)(System::TObject* Sender, TcsWasabiHeaderEventParams *e);
__property TcsWasabiHeaderEvent OnHeader = { read=FOnHeader, write=FOnHeader };

Remarks

The Field parameter contains the name of the HTTP header (which is the same as it is delivered). The Value parameter contains the header contents.

If the header line being retrieved is a continuation header line, then the Field parameter contains "" (empty string).

Log Event (Wasabi Component)

Fired once for each log message.

Syntax

typedef struct {
  int LogLevel;
  String Message;
  String LogType;
} TcsWasabiLogEventParams;
typedef void __fastcall (__closure *TcsWasabiLogEvent)(System::TObject* Sender, TcsWasabiLogEventParams *e);
__property TcsWasabiLogEvent OnLog = { read=FOnLog, write=FOnLog };

Remarks

This event is fired once for each log message generated by the component. The verbosity is controlled by the LogLevel setting.

LogLevel indicates the level of message. Possible values are as follows:

The value 1 (Info) logs basic information, including the URL, HTTP version, and status details.

The value 2 (Verbose) logs additional information about the request and response.

The value 3 (Debug) logs the headers and body for both the request and response, as well as additional debug information (if any).

Message is the log entry.

LogType identifies the type of log entry. Possible values are as follows:

• "Info"
• "RequestHeaders"
• "ResponseHeaders"
• "RequestBody"
• "ResponseBody"
• "ProxyRequest"
• "ProxyResponse"
• "FirewallRequest"

typedef void __fastcall (__closure *TcsWasabiMetadataListEvent)(System::TObject* Sender, TcsWasabiMetadataListEventParams *e);
__property TcsWasabiMetadataListEvent OnMetadataList = { read=FOnMetadataList, write=FOnMetadataList };

Remarks

This event fires once for each metadata item returned when GetObjectInfo is called.

Name is the name of the metadata item, without the service-specific prefix (e.g., x-amz-meta-, x-goog-meta-, etc.). Keep in mind that the server stores metadata names in lowercase.

Value is the metadata item's value.

ObjectList Event (Wasabi Component)

} TcsWasabiObjectListEventParams;
typedef void __fastcall (__closure *TcsWasabiObjectListEvent)(System::TObject* Sender, TcsWasabiObjectListEventParams *e);
__property TcsWasabiObjectListEvent OnObjectList = { read=FOnObjectList, write=FOnObjectList };

Remarks

This event fires once for each object, object version, or multipart upload returned when GetObjectInfo, ListObjects, ListVersions, or ListMultipartUploads is called.

BucketName reflects the name of the bucket that the object is in.

ObjectName reflects the name of the object.

LastModified reflects the last modified time of the object. Not applicable when ListMultipartUploads is called.

Size reflects the size, in bytes, of the object. Not applicable when ListMultipartUploads is called.

ETag reflects the object's ETag. Not applicable when ListMultipartUploads is called.

OwnerId and OwnerName reflect the Id and display name of the object's owner, respectively. Not applicable when GetObjectInfo is called.

UploadId reflects the Id of the multipart upload. Only applicable when ListMultipartUploads is called.

VersionId reflects the Id of the object version (note that the string null is a valid version Id). Only applicable when ListVersions is called, or when GetObjectInfo is called while VersionId is non-empty; empty in all other cases.

LatestVersion indicates whether this is the latest object version. Only applicable when ListVersions is called; true in all other cases.

Deleted indicates whether this object version is a delete marker (refer to DeleteObject for more information). Only applicable when ListVersions is called, or when GetObjectInfo is called while VersionId is non-empty; false in all other cases.

PartList Event (Wasabi Component)

Fires once for every part returned when listing a multipart upload's parts.

Syntax

typedef struct {
  int PartNumber;
  String ObjectName;
  String LastModified;
  __int64 Size;
  String ETag;
  String OwnerId;
  String OwnerName;
} TcsWasabiPartListEventParams;
typedef void __fastcall (__closure *TcsWasabiPartListEvent)(System::TObject* Sender, TcsWasabiPartListEventParams *e);
__property TcsWasabiPartListEvent OnPartList = { read=FOnPartList, write=FOnPartList };

Remarks

LastModified reflects the last modified time of the part.

Size reflects the size, in bytes, of the part.

ETag reflects the part's ETag of the part.

OwnerId and OwnerName reflect the Id and display name of the part's owner, respectively.

PrefixList Event (Wasabi Component)

Fires once for each common prefix returned when listing objects.

Syntax

typedef struct {
  String BucketName;
  String Prefix;
} TcsWasabiPrefixListEventParams;
typedef void __fastcall (__closure *TcsWasabiPrefixListEvent)(System::TObject* Sender, TcsWasabiPrefixListEventParams *e);
__property TcsWasabiPrefixListEvent OnPrefixList = { read=FOnPrefixList, write=FOnPrefixList };

Remarks

This event fires once for each common prefix returned when ListObjects or ListVersions is called when ObjectDelimiter is non-empty. Refer to ObjectDelimiter for more information.

BucketName reflects the name of the bucket that the prefix is in.

Prefix is the common prefix.

Progress Event (Wasabi Component)

Fires during an upload or download to indicate transfer progress.

Syntax

typedef struct {
  int Direction;
  __int64 BytesTransferred;
  __int64 TotalBytes;
  int PercentDone;
} TcsWasabiProgressEventParams;
typedef void __fastcall (__closure *TcsWasabiProgressEvent)(System::TObject* Sender, TcsWasabiProgressEventParams *e);
__property TcsWasabiProgressEvent OnProgress = { read=FOnProgress, write=FOnProgress };

Remarks

This event fires during an upload or download to indicate the progress of the transfer of the entire request. By default, this event will fire each time PercentDone increases by one percent; the ProgressStep configuration setting can be used to alter this behavior.

Direction indicates whether the transfer is an upload (0) or a download (1).

BytesTransferred reflects the number of bytes that have been transferred so far, or 0 if the transfer is starting (however, see note below).

TotalBytes reflects the total number of bytes that are to be transferred, or -1 if the total is unknown. This amount includes the size of everything in the request like HTTP headers.

PercentDone reflects the overall progress of the transfer, or -1 if the progress cannot be calculated.

Note: By default, the component tracks transfer progress absolutely. If a transfer is interrupted and later resumed, the values reported by this event upon and after resumption will account for the data that was transferred before the interruption.

For example, if 10MB of data was successfully transferred before the interruption, then this event will fire with a BytesTransferred value of 10485760 (10MB) when the transfer is first resumed, and then continue to fire with successively greater values as usual.

This behavior can be changed by disabling the ProgressAbsolute configuration setting, in which case the component will treat resumed transfers as "new" transfers. In this case, the BytesTransferred parameter will always be 0 the first time this event fires, regardless of whether the transfer is new or being resumed.

SSLServerAuthentication Event (Wasabi Component)

Fired after the server presents its certificate to the client.

Syntax

typedef struct {
  String CertEncoded;
  DynamicArray<Byte> CertEncodedB;
  String CertSubject;
  String CertIssuer;
  String Status;
  bool Accept;
} TcsWasabiSSLServerAuthenticationEventParams;
typedef void __fastcall (__closure *TcsWasabiSSLServerAuthenticationEvent)(System::TObject* Sender, TcsWasabiSSLServerAuthenticationEventParams *e);
__property TcsWasabiSSLServerAuthenticationEvent OnSSLServerAuthentication = { read=FOnSSLServerAuthentication, write=FOnSSLServerAuthentication };

Remarks

During this event, the client can decide whether or not to continue with the connection process. The Accept parameter is a recommendation on whether to continue or close the connection. This is just a suggestion: application software must use its own logic to determine whether or not to continue.

When Accept is False, Status shows why the verification failed (otherwise, Status contains the string OK). If it is decided to continue, you can override and accept the certificate by setting the Accept parameter to True.

SSLStatus Event (Wasabi Component)

Fired when secure connection progress messages are available.

Syntax

typedef struct {
  String Message;
} TcsWasabiSSLStatusEventParams;
typedef void __fastcall (__closure *TcsWasabiSSLStatusEvent)(System::TObject* Sender, TcsWasabiSSLStatusEventParams *e);
__property TcsWasabiSSLStatusEvent OnSSLStatus = { read=FOnSSLStatus, write=FOnSSLStatus };

Remarks

The event is fired for informational and logging purposes only. This event tracks the progress of the connection.

StartTransfer Event (Wasabi Component)

This event fires when a document starts transferring (after the headers).

Syntax

typedef struct {
  int Direction;
} TcsWasabiStartTransferEventParams;
typedef void __fastcall (__closure *TcsWasabiStartTransferEvent)(System::TObject* Sender, TcsWasabiStartTransferEventParams *e);
__property TcsWasabiStartTransferEvent OnStartTransfer = { read=FOnStartTransfer, write=FOnStartTransfer };

Remarks

The StartTransfer event is fired when the document text starts transferring from the server to the local host.

The Direction parameter shows whether the client (0) or the server (1) is sending the data.

Transfer Event (Wasabi Component)

Fired while a document transfers (delivers document).

Syntax

typedef struct {
  int Direction;
  __int64 BytesTransferred;
  int PercentDone;
  String Text;
  DynamicArray<Byte> TextB;
} TcsWasabiTransferEventParams;
typedef void __fastcall (__closure *TcsWasabiTransferEvent)(System::TObject* Sender, TcsWasabiTransferEventParams *e);
__property TcsWasabiTransferEvent OnTransfer = { read=FOnTransfer, write=FOnTransfer };

Remarks

The Text parameter contains the portion of the document text being received. It is empty if data are being posted to the server.

The BytesTransferred parameter contains the number of bytes transferred in this Direction since the beginning of the document text (excluding HTTP response headers).

The Direction parameter shows whether the client (0) or the server (1) is sending the data.

The PercentDone parameter shows the progress of the transfer in the corresponding direction. If PercentDone can not be calculated the value will be -1.

Note: Events are not re-entrant. Performing time-consuming operations within this event will prevent it from firing again in a timely manner and may affect overall performance.

Config Settings (Wasabi Component)

Wasabi Config Settings

<firstlevel>
  <one>value</one>
  <two>
    <item>first</item>
    <item>second</item>
  </two>
  <three>value three</three>
