Class ObjectWriter

java.lang.Object
  java.lang.Thread
      gate.util.ObjectWriter

All Implemented Interfaces:

Runnable

public class ObjectWriter
extends Thread

Writes an object to an PipedOutputStream wich can be connected to a PipedInputStream. Before writting the object it also writes it in a buffer and finds out its size so it can be reported via getSize method. All read/writes occur in separate threads to avoid a deadlock.
