Class LzmaExistingWritableFileProxy

java.lang.Object
  org.schmant.task.at4j.lzma.AbstractLzmaWritableFileProxy
      org.schmant.task.at4j.lzma.LzmaExistingWritableFileProxy

All Implemented Interfaces:

Lockable, WriteLockable, WritableFile

public class LzmaExistingWritableFileProxy
extends AbstractLzmaWritableFileProxy

This proxy LZMA encodes data written to another, already existing WritableFile. It can be used together with the ArgumentInterpreter.

Warning: LZMA compression does not seem to work reliably. Sometimes, when compressing, it seems to want to allocate too much (very much) memory, and that often leads to an OutOfMemoryError. Avoid using this class until the issue is fixed.

The difference between this object and the LzmaWritableFile is that this object uses the ArgumentInterpreter for interpreting the proxied file object.

The proxied object is interpreted using InterpretAsWritableFileStrategy.
