de.humatic.dsj
Class CompressedJavaSource

java.lang.Object
  de.humatic.dsj.DSFilter
      de.humatic.dsj.CompressedJavaSource

All Implemented Interfaces:

java.beans.PropertyChangeListener, java.util.EventListener

public class CompressedJavaSource
extends DSFilter
implements java.beans.PropertyChangeListener

Custom DSFilter object working together with the native dsj_CompressedJavaSource & dsj_AsyncJavaSource DirectShow filters. The combination of this java class and its native counterparts allow to feed compressed data, aquired on the java side, into a DirectShow filtergraph. dsj uses this with all the classes in the de.humatic.dsj.src package.
Instances of this class are created by the Source objects via calls to DSGraph.insertCompressedSourceFilter(...).
