Class SimpleSourceSink

java.lang.Object
  net.sourceforge.xwing.AbstractSourceSink
      net.sourceforge.xwing.SimpleSourceSink

All Implemented Interfaces:

SourceSink

public class SimpleSourceSink

extends AbstractSourceSink

A SourceSink that internally stores any arbitrary Object as its value. If a new value is set via set(), a ChangeEvent wil be broadcast. If the value's internal state changes, though, no event will be broadcast because we have no generic way of knowing if that has happened.
