Linode Class

Properties   Methods   Events   Config Settings   Errors  

The Linode class provides an easy way to interface with Linode's Object Storage service.

Syntax

Linode

Remarks

The Linode Object Storage service has an API that is compatible with that of Amazon S3, allowing you to store arbitrary data using the same bucket-and-object paradigm that S3 uses.

To use the Linode class, you will first need to sign up for the Linode Object Storage 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.

There are other methods such as ListBuckets, ListObjects, GetObject, GetLink, DeleteObject etc. that further enable you to manage your data store.

Default Value

""

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 class 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:

Range Property (Linode Class)

The range of bytes to request.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
char* GetRange();
int SetRange(const char* lpszRange);

Unicode (Windows)
LPWSTR GetRange();
INT SetRange(LPCWSTR lpszRange);

char* cloudstorage_linode_getrange(void* lpObj);
int cloudstorage_linode_setrange(void* lpObj, const char* lpszRange);

QString GetRange();
int SetRange(QString qsRange);

Default Value

""

Remarks

This property specifies the range of bytes to request from the server. If this property is non-empty when a GetObject request is being constructed, a header like Range: bytes=Range will be added to the request, with Range substituted with the specified value.

There are two valid formats for this property's value:

• StartByte-
• StartByte-EndByte

Note: If the StartByte property is greater than zero when GetObject is called (i.e., when a download is being resumed), and this property is non-empty, the class will automatically advance the StartByte value in the specified range by StartByte bytes when sending the Range header to the server. This ensures that the previously-downloaded data at the start of the specified range is not downloaded again when the download is resumed.

This property is not available at design time.

Data Type

String

Region Property (Linode Class)

The region the class will make requests against.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
char* GetRegion();
int SetRegion(const char* lpszRegion);

Unicode (Windows)
LPWSTR GetRegion();
INT SetRegion(LPCWSTR lpszRegion);

char* cloudstorage_linode_getregion(void* lpObj);
int cloudstorage_linode_setregion(void* lpObj, const char* lpszRegion);

QString GetRegion();
int SetRegion(QString qsRegion);

Default Value

"us-east-1"

Remarks

This property control which region the class will make requests against. By default the class uses us-east-1. This property should be changed to create or access resources in other regions.

Regions:

Important: Each "region" supported by Linode's Object Storage service is actually a completely standalone storage cluster. These clusters do not interact with each other in any way, which causes the following non-standard behaviors:

• Bucket names may be reused in each region (however, they must still be "globally" unique within each region).
• The ListBuckets method will only return buckets located in the currently-selected region; there is no way to retrieve a list of all regions' buckets.
• Similarly, the BucketExists and GetBucketLocation methods only consider buckets located in the currently-selected region.
• The CopyObject method cannot be used to copy objects to a bucket in another region.

The class will always convert this property's value to lowercase. If this property is cleared, the class will reset it to the default value.

Data Type

String

SecretKey Property (Linode Class)

The secret key to use for authentication.

"MY"

Remarks

This is the name of the certificate store for the client certificate.

The SSLCertStoreType property denotes the type of the certificate store specified by SSLCertStore. If the store is password protected, specify the password in SSLCertStorePassword.

SSLCertStore is used in conjunction with the SSLCertSubject property to specify client certificates. If SSLCertStore has a value, and SSLCertSubject or SSLCertEncoded is set, a search for a certificate is initiated. Please see the SSLCertSubject property for details.

Designations of certificate stores are platform dependent.

The following designations are the most common User and Machine certificate stores in Windows:

When the certificate store type is PFXFile, this property must be set to the name of the file. When the type is PFXBlob, the property must be set to the binary contents of a PFX file (i.e., PKCS#12 certificate store).

int cloudstorage_linode_setsslcertsubject(void* lpObj, const char* lpszSSLCertSubject);

QString GetSSLCertSubject();
int SetSSLCertSubject(QString qsSSLCertSubject);

Default Value

""

Remarks

This is 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.

int cloudstorage_linode_setsslprovider(void* lpObj, int iSSLProvider);

int GetSSLProvider();
int SetSSLProvider(int iSSLProvider);

Default Value

0

Remarks

This property specifies the SSL/TLS implementation to use. In most cases the default value of 0 (Automatic) is recommended and should not be changed. When set to 0 (Automatic) the class will select whether to use the platform implementation or the internal implementation depending on the operating system as well as the TLS version being used.

Possible values are:

In most cases using the default value (Automatic) is recommended. The class will select a provider depending on the current platform.

When Automatic is selected, on Windows the class will use the platform implementation. On Linux/macOS the class will use the internal implementation. When TLS 1.3 is enabled via SSLEnabledProtocols the internal implementation is used on all platforms.

Data Type

Integer

SSLServerCertEncoded Property (Linode Class)

This is the certificate (PEM/Base64 encoded).

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
int GetSSLServerCertEncoded(char* &lpSSLServerCertEncoded, int &lenSSLServerCertEncoded);

Unicode (Windows)

QByteArray GetSSLServerCertEncoded();

Default Value

""

Remarks

This is 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

Binary String

StartByte Property (Linode Class)

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

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
int64 GetStartByte();
int SetStartByte(int64 lStartByte);

Unicode (Windows)
LONG64 GetStartByte();
INT SetStartByte(LONG64 lStartByte);

int64 cloudstorage_linode_getstartbyte(void* lpObj);
int cloudstorage_linode_setstartbyte(void* lpObj, int64 lStartByte);

qint64 GetStartByte();
int SetStartByte(qint64 lStartByte);

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.

When uploading from a stream, the class will always seek forward in the stream if the value of StartByte is greater than 0 when CreateObject is called. Keep this in mind when resuming interrupted object uploads.

This property is not available at design time.

Data Type

Long64

Timeout Property (Linode Class)

A timeout for the class.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
int GetTimeout();
int SetTimeout(int iTimeout);

Unicode (Windows)
INT GetTimeout();
INT SetTimeout(INT iTimeout);

int cloudstorage_linode_gettimeout(void* lpObj);
int cloudstorage_linode_settimeout(void* lpObj, int iTimeout);

int GetTimeout();
int SetTimeout(int iTimeout);

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 class will wait for the operation to complete before returning control.

The class 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 class fails with an error.

Please note that by default, all timeouts are inactivity timeouts, i.e. 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

UseVirtualHosting Property (Linode Class)

Determines which style request to use.

int cloudstorage_linode_setversioningenabled(void* lpObj, int bVersioningEnabled);

bool GetVersioningEnabled();
int SetVersioningEnabled(bool bVersioningEnabled);

Default Value

FALSE

Remarks

This property can be used to query and control 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 property will always return false when queried, and any attempts to set it will fail.

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

This property is not available at design time.

Data Type

Boolean

Unicode (Windows)
INT AbortMultipartUpload(LPCWSTR lpszObjectName, LPCWSTR lpszUploadId);

int cloudstorage_linode_abortmultipartupload(void* lpObj, const char* lpszObjectName, const char* lpszUploadId);

int AbortMultipartUpload(const QString& qsObjectName, const QString& qsUploadId);

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.

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)

AddMetadata Method (Linode Class)

Adds a metadata item to the Metadata properties.

Syntax

• C++

int cloudstorage_linode_addmetadata(void* lpObj, const char* lpszName, const char* lpszValue);

int AddMetadata(const QString& qsName, const QString& qsValue);

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 class will take care of prepending it when sending metadata to the server.

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)

AddQueryParam Method (Linode Class)

Adds a query parameter to the QueryParams properties.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
int AddQueryParam(const char* lpszName, const char* lpszValue);

Unicode (Windows)
INT AddQueryParam(LPCWSTR lpszName, LPCWSTR lpszValue);

int cloudstorage_linode_addqueryparam(void* lpObj, const char* lpszName, const char* lpszValue);

int AddQueryParam(const QString& qsName, const QString& qsValue);

Remarks

This method is used to add a query parameter to the QueryaParam* 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 class automatically. Consult the service documentation for details on the available parameters.

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)

BucketExists Method (Linode Class)

Checks whether the bucket exists.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
int BucketExists();

Unicode (Windows)
INT BucketExists();

int cloudstorage_linode_bucketexists(void* lpObj);

bool BucketExists();

Remarks

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

Note: This method only considers buckets located in the currently-selected Region. Refer to the Region property's documentation for more information.

Error Handling (C++)

This method returns a Boolean value; after it returns, call the GetLastErrorCode() method to obtain its result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message.

CheckVersioningEnabled Method (Linode Class)

Checks whether versioning is enabled for the currently selected bucket.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
int CheckVersioningEnabled();

Unicode (Windows)
INT CheckVersioningEnabled();

int cloudstorage_linode_checkversioningenabled(void* lpObj);

bool 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.

Error Handling (C++)

This method returns a Boolean value; after it returns, call the GetLastErrorCode() method to obtain its result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message.

CompleteMultipartUpload Method (Linode Class)

Completes a multipart upload by assembling previously uploaded parts.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
int CompleteMultipartUpload(const char* lpszObjectName, const char* lpszUploadId);

Unicode (Windows)
INT CompleteMultipartUpload(LPCWSTR lpszObjectName, LPCWSTR lpszUploadId);

int cloudstorage_linode_completemultipartupload(void* lpObj, const char* lpszObjectName, const char* lpszUploadId);

int CompleteMultipartUpload(const QString& qsObjectName, const QString& qsUploadId);

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.

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)

Config Method (Linode Class)

Sets or retrieves a configuration setting.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
char* Config(const char* lpszConfigurationString);

Unicode (Windows)
LPWSTR Config(LPCWSTR lpszConfigurationString);

char* cloudstorage_linode_config(void* lpObj, const char* lpszConfigurationString);

QString Config(const QString& qsConfigurationString);

Remarks

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

These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the class, 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.

Error Handling (C++)

This method returns a String value; after it returns, call the GetLastErrorCode() method to obtain its result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message.

CopyObject Method (Linode Class)

Copies an object.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
int CopyObject(const char* lpszSrcObjectName, const char* lpszDestBucket, const char* lpszDestObjectName);

Unicode (Windows)
INT CopyObject(LPCWSTR lpszSrcObjectName, LPCWSTR lpszDestBucket, LPCWSTR lpszDestObjectName);

int cloudstorage_linode_copyobject(void* lpObj, const char* lpszSrcObjectName, const char* lpszDestBucket, const char* lpszDestObjectName);

int CopyObject(const QString& qsSrcObjectName, const QString& qsDestBucket, const QString& qsDestObjectName);

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.

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)

CopyPart Method (Linode Class)

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

• C
• Qt

ANSI (Cross Platform)
int CopyPart(const char* lpszSrcObjectName, const char* lpszDestBucket, const char* lpszDestObjectName, int iDestPartNumber, const char* lpszDestUploadId);

Unicode (Windows)
INT CopyPart(LPCWSTR lpszSrcObjectName, LPCWSTR lpszDestBucket, LPCWSTR lpszDestObjectName, INT iDestPartNumber, LPCWSTR lpszDestUploadId);

int cloudstorage_linode_copypart(void* lpObj, const char* lpszSrcObjectName, const char* lpszDestBucket, const char* lpszDestObjectName, int iDestPartNumber, const char* lpszDestUploadId);

int CopyPart(const QString& qsSrcObjectName, const QString& qsDestBucket, const QString& qsDestObjectName, int iDestPartNumber, const QString& qsDestUploadId);

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.

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)

Unicode (Windows)
INT CreateBucket();

int cloudstorage_linode_createbucket(void* lpObj);

int 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.

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)

CreateObject Method (Linode Class)

Creates a new object in the currently selected bucket.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
int CreateObject(const char* lpszObjectName);

Unicode (Windows)
INT CreateObject(LPCWSTR lpszObjectName);

int cloudstorage_linode_createobject(void* lpObj, const char* lpszObjectName);

int CreateObject(const QString& qsObjectName);

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 SetUploadStream has been used to set an upload stream, it will take priority as the data source. 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 class 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 class 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.

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)

DeleteBucket Method (Linode Class)

Deletes a bucket.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
int DeleteBucket();

Unicode (Windows)
INT DeleteBucket();

int cloudstorage_linode_deletebucket(void* lpObj);

int 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.

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message.

DeleteObject Method (Linode Class)

Deletes an object.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
int DeleteObject(const char* lpszObjectName);

Unicode (Windows)
INT DeleteObject(LPCWSTR lpszObjectName);

int cloudstorage_linode_deleteobject(void* lpObj, const char* lpszObjectName);

int DeleteObject(const QString& qsObjectName);

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.

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message.

• Qt

ANSI (Cross Platform)
int DoEvents();

Unicode (Windows)
INT DoEvents();

int cloudstorage_linode_doevents(void* lpObj);

• Qt

ANSI (Cross Platform)
char* GetBucketLocation();

Unicode (Windows)
LPWSTR GetBucketLocation();

char* cloudstorage_linode_getbucketlocation(void* lpObj);

QString GetBucketLocation();

Remarks

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

Note: This method only considers buckets located in the currently-selected Region. Refer to the Region property's documentation for more information.

Error Handling (C++)

This method returns a String value; after it returns, call the GetLastErrorCode() method to obtain its result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution.

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.

Error Handling (C++)

This method returns a String value; after it returns, call the GetLastErrorCode() method to obtain its result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message.

GetObject Method (Linode Class)

Downloads an object.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
int GetObject(const char* lpszObjectName);

Unicode (Windows)
INT GetObject(LPCWSTR lpszObjectName);

int cloudstorage_linode_getobject(void* lpObj, const char* lpszObjectName);

int GetObject(const QString& qsObjectName);

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 a stream has been specified using SetDownloadStream, the object data will be sent through it. If a stream is not specified, and 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 class 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 class 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);

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)

int cloudstorage_linode_getobjectinfo(void* lpObj, const char* lpszObjectName);

int GetObjectInfo(const QString& qsObjectName);

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* properties.

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message.

• Qt

ANSI (Cross Platform)
int ListBuckets();

Unicode (Windows)
INT ListBuckets();

int cloudstorage_linode_listbuckets(void* lpObj);

int ListBuckets();

Remarks

This method lists all buckets in the currently-selected Region. (Due to the architecture of the Linode Object Storage service, there is no way to retrieve a list of all regions' buckets; refer to the Region property for more information.)

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

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message.

Unicode (Windows)
INT ListMultipartUploads();

int cloudstorage_linode_listmultipartuploads(void* lpObj);

int 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.

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message.

int 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.

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:

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message.

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.

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

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message.

int SendCustomRequest(const QString& qsHttpMethod, const QString& qsObjectName, const QString& qsRequestBody);

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 class 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)
   • QueryParam*
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 ParsedHeader* properties; and the response body in the stream specified using SetDownloadStream, 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.

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message.

int cloudstorage_linode_setdownloadstream(void* lpObj, CloudStorageStream* sDownloadStream);

int SetDownloadStream(CloudStorageStream* sDownloadStream);

Remarks

If a download stream is set before data is downloaded, the downloaded data will be written to the stream. The stream should be open and normally set to position 0.

Note: Passing a non-null value for DownloadStream will cause LocalFile to be cleared. Similarly, setting LocalFile to a non-empty value will discard any stream set using this method.

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message.
