JarData Property

(Decompression only) The jar file contents as a byte array.


 setJarData(jarData: Uint8Array): void;

Default Value



Normally you should set ArchiveFile before invoking Scan or Extract. If you prefer to read the jar file from memory you may set JarData instead. JarData should be set to the entire contents of the jar file; this will allow you to read from the archive without writing any temporary files to disk.

If you would like to extract data from the archive without ever writing to disk you should also set WriteToProgressEvent to true, and after invoking Scan, you should set the value of FilesDecompressedName for each file in the Files collection to an empty string. Then, when you invoke Extract (or ExtractAll) the data will be provided in the Progress event.

This property is write-only. Note that modifying a jar file stored in JarData is not supported, so Append, Delete, etc., will throw exceptions.

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