Class FilterGraphProcessor

java.lang.Object
  net.sf.fmj.filtergraph.FilterGraphProcessor

public final class FilterGraphProcessor
extends java.lang.Object

Execute functions on filter graphs. Does not actually represent the graph itself, that would be simply a FilterGraphNode being used as a root. TODO: if a demux for example sets both discard and eom, what are the semantics? It appears that we will discard the EOM.
