Provide the path to the files on a local system (e.g. C:\photos) via the LocalPath parameter, and set Recursive to indicate whether you want to process the subdirectories recursively. Pass the desired mount point for the files within the archive (e.g. Backup2020/photos) via the Folder parameter.

You can use file mask wildcards in LocalPath to only select the files that match the mask.

AddVirtual Method (SecureBlackbox_ArchiveWriter Class)

Adds a file placeholder to the archive.

Object Oriented Interface

public function doAddVirtual($path);

Procedural Interface

secureblackbox_archivewriter_do_addvirtual($res, $path);

Remarks

Use this method to add a placeholder for the entry the contents of which is to be provided on the fly from a stream or buffer.

Pass the path to the entry within the archive (e.g. Reports/report2020.csv) via the Path parameter. After the entry has been added, use PrepareFile event or Files property to tune up the type of the data source (file, stream, or memory buffer). During the actual compression, provide the contents of the entry in a stream or buffer in the BeforeCompressFile event handler.

This method returns the index of the new entry in the Files collection.

Close Method (SecureBlackbox_ArchiveWriter Class)

Closes the archive.

Object Oriented Interface

Config Method (SecureBlackbox_ArchiveWriter Class)

Sets or retrieves a configuration setting.

Object Oriented Interface

public function doConfig($configurationstring);

Procedural Interface

secureblackbox_archivewriter_do_config($res, $configurationstring);

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.

CreateNew Method (SecureBlackbox_ArchiveWriter Class)

Creates a new archive.

Object Oriented Interface

public function doCreateNew($archivetype);

Procedural Interface

secureblackbox_archivewriter_do_createnew($res, $archivetype);

The archive will be kept in memory until written down with Save or SaveStream method.

DoAction Method (SecureBlackbox_ArchiveWriter Class)

Performs an additional action.

Object Oriented Interface

public function doDoAction($actionid, $actionparams);

Procedural Interface

secureblackbox_archivewriter_do_doaction($res, $actionid, $actionparams);

Remarks

DoAction is a generic method available in every class. It is used to perform an additional action introduced after the product major release. The list of actions is not fixed, and may be flexibly extended over time.

The unique identifier (case insensitive) of the action is provided in the ActionID parameter.

ActionParams contains the value of a single parameter, or a list of multiple parameters for the action in the form of PARAM1=VALUE1;PARAM2=VALUE2;....

Open Method (SecureBlackbox_ArchiveWriter Class)

Object Oriented Interface

public function doRemove($path);

Procedural Interface

secureblackbox_archivewriter_do_remove($res, $path);

Path supports file masks, which makes this method quite powerful (and potentially dangerous).

Reset Method (SecureBlackbox_ArchiveWriter Class)

Resets the class settings.

Object Oriented Interface

public function doReset();

Procedural Interface

secureblackbox_archivewriter_do_reset($res);

Remarks

Reset is a generic method available in every class.

Save Method (SecureBlackbox_ArchiveWriter Class)

Compresses the archive and saves it to a file.

Object Oriented Interface

public function doSave($archivename);

Procedural Interface

secureblackbox_archivewriter_do_save($res, $archivename);

Remarks

Use this method to finalize all preparations, compress all the entries set up in Files collection, and write the created archive to ArchiveName file.

This method carries out a lot of work and fires a number of events during its execution. Before the compression process starts, PrepareFile event fires repeatedly to provide the summary of what is being included into the archive. A handler of that event is a good place to make last-minute modifications to the data sources, file names, and actions to take upon the files.

Compression of each entry is surrounded with BeforeCompressFile and AfterCompressFile "brackets". Subscribe to BeforeCompressFile to supply the file contents for entries with Buffer and Stream data sources. AfterCompressFile is a good place to release the content stream alloated in the BeforeCompressFile event handler.

Progress event fires repeatedly to report the progress of the current and whole operations. It also provides an opportunity to abort the compression process.

SaveBytes Method (SecureBlackbox_ArchiveWriter Class)

Compresses the archive and saves it to a byte array.

Object Oriented Interface

public function doSaveBytes();

Procedural Interface

secureblackbox_archivewriter_do_savebytes($res);

Remarks

Remarks

This method is a powerful way to update a subset of files in the archive in accordance with a specified criteria.

Pass an archive-local name of the folder to update via the Folder parameter, and the system-local version of the same folder via the LocalPath parameter. Set AddMissingFiles and RemoveMissingFiles as needed to force inclusion of files missing from the archive, or removal of files missing locally, accordingly.

The Recursive parameter specifies whether the directory should be browsed recursively.

Use this event handler to adjust the data source if the file is to be loaded from a stream or buffer. The DataSource parameter indicates the type of the data media:

If passing the data from a stream or buffer, use AfterCompressFile to dispose of any objects allocated in this event handler (such as the source stream).

The Path parameter contains the path to the file within the archive (such as Photos/myphoto.jpg), and the FileSize contains the size of that file before compression.

The DataSource parameter indicates the media from which the file contents is to be taken. A typical default value if fdsFile, but you can adjust the value of that parameter if you need to use an alternative source. The following options are available:

Please do not assign FileStream or FileData in this event handler: this should be done further down the road in the BeforeCompressFile event handler. The purpose of this event is to prepare the compression plan by summarizing what should be done and to which files.

The Action parameter, which is also tuneable, indicates the action for class to take on the file:

Please note that the certificate must have an associated private key to be capable of decryption.

Config Settings (ArchiveWriter Class)

The class accepts one or more of the following configuration settings. Configuration settings are similar in functionality to properties, but they are rarely used.
