Bzip2 Configuration

The component accepts one or more of the following configuration settings. Configuration 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.

Bzip2 Configuration Settings


	CloseStreamAfterCompress: If true, the component will close the output stream after compression. This property is true by default. Therefore, by default, the output stream will be closed after compression is completed. In order to keep streams open after the compression completes, you must set this config to false.
	MergeExtractedData: If true, the component will merge concatenated data into one output file when decompressing. While the bzip2 file format is typically used only to archive a single file, multiple files can be concatenated into one bzip2 file. This configuration setting can be used to into one output file when decompressing.
	WriteToProgressEvent: Whether or not to write data to the Progress Event. If WriteToProgressEvent is set to true, then all data produced through invocations of Extract, ExtractAll, and Compress will be written to the Progress event as well as to disk. Applications may stream out the compressed or decompressed data by trapping this event and copying the data. If WriteToProgressEvent is set to false, the data will not be streamed out, and the Data parameter of the Progress event will contain null. By default, this config is set to false.

Base Configuration Settings

GUIAvailable: Tells the component whether or not a message loop is available for processing events.

In a GUI-based application, long-running blocking operations may cause the application to stop responding to input until the operation returns. The component will attempt to discover whether or not the application has a message loop and, if one is discovered, it will process events in that message loop during any such blocking operation.

In some non-GUI applications an invalid message loop may be discovered that will result in errant behavior. In these cases, setting GuiAvailable to false will ensure that the component does not attempt to process external events.

UseDaemonThreads: Whether threads created by the component are daemon threads.

If set to True, when the component creates a thread the thread's Daemon property will be explicitly set to True. By default this setting is False and the component will not set the Daemon property on the created thread.
