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)

Opens an archive file.

Object Oriented Interface

public function doOpen($archivetype, $archivename);

Procedural Interface

secureblackbox_archivewriter_do_open($res, $archivetype, $archivename);

Remarks

Use this method to open an existing archive file for modification.

Provide the path to the archive file via the ArchiveName parameter, and pass the archive type in the ArchiveType parameter.

The following archive types are currently supported:

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

OpenBytes Method (SecureBlackbox_ArchiveWriter Class)

Loads an archive file from a byte array.

Object Oriented Interface

public function doOpenBytes($archivetype, $archivebytes);

Procedural Interface

secureblackbox_archivewriter_do_openbytes($res, $archivetype, $archivebytes);

Remarks

Use this method to load an existing archive file from a byte array.

Provide the archive stream via the ArchiveBytes parameter, and pass the archive type in the ArchiveType parameter.

The following archive types are currently supported:

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

Remove Method (SecureBlackbox_ArchiveWriter Class)

Removes file(s) and/or folder(s) from the archive.

Object Oriented Interface

public function doRemove($path);

Procedural Interface

secureblackbox_archivewriter_do_remove($res, $path);

Remarks

Use this method to remove entries from the archive. Provide an archive-local path via the Path parameter.

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

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

Use this method to finalize all preparations and compress all entries contained in the Files collection. The method returns the byte array containing the serialized archive.

You can fine-tune the compression process by providing compression details on the fly via the events class fires. See the description of the Save method for the details.

UpdateFile Method (SecureBlackbox_ArchiveWriter Class)

Updates an existing compressed entry with a fresher local version.

Object Oriented Interface

public function doUpdateFile($path, $localpath);

Procedural Interface

secureblackbox_archivewriter_do_updatefile($res, $path, $localpath);

Remarks

Call this method to update the Path entry in the archive with a fresher entry at LocalPath.

UpdateFiles Method (SecureBlackbox_ArchiveWriter Class)

Updates a selection of files in the archive.

Object Oriented Interface

public function doUpdateFiles($folder, $localpath, $addmissingfiles, $removemissingfiles, $recursive);

Procedural Interface

secureblackbox_archivewriter_do_updatefiles($res, $folder, $localpath, $addmissingfiles, $removemissingfiles, $recursive);

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.

UpdateVirtual Method (SecureBlackbox_ArchiveWriter Class)

Updates an entry in the archive with on-the-fly content.

Object Oriented Interface

public function doUpdateVirtual($path);

Procedural Interface

secureblackbox_archivewriter_do_updatevirtual($res, $path);

Remarks

Use this method to update content of an existing archive entry. Pass the archive-local entry path via the Path parameter. After updating the entry, tune up its DataSource property in accordance with the desired content origin. Subscribe to BeforeCompressFile to supply the actual data via FileData or FileStream properties.

AfterCompressFile Event (SecureBlackbox_ArchiveWriter Class)

Marks the completion of compression of a file.

Object Oriented Interface

public function fireAfterCompressFile($param);

Procedural Interface

secureblackbox_archivewriter_register_callback($res, 1, array($this, 'fireAfterCompressFile'));

Parameter List

 'path'
 'filesize'
 'datasource'

Remarks

Subscribe to this event to get notified about the completion of compression of a file.

The Path parameter specifies the internal path to the entry inside the archive. The FileSize indicates the size of the file before compression, and the DataSource specifies the type of the source media.

BeforeCompressFile Event (SecureBlackbox_ArchiveWriter Class)

Marks the start of compression of a file.

Object Oriented Interface

public function fireBeforeCompressFile($param);

Procedural Interface

secureblackbox_archivewriter_register_callback($res, 2, array($this, 'fireBeforeCompressFile'));

Parameter List

 'path'
 'filesize'

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:

Progress Event (SecureBlackbox_ArchiveWriter Class)
