hudson.remoting
Class FastPipedOutputStream

java.lang.Object
  java.io.OutputStream
      hudson.remoting.FastPipedOutputStream

All Implemented Interfaces:

Closeable, Flushable

public class FastPipedOutputStream
extends OutputStream

This class is equivalent to java.io.PipedOutputStream. In the interface it only adds a constructor which allows for specifying the buffer size. Its implementation, however, is much simpler and a lot more efficient than its equivalent. It doesn't rely on polling. Instead it uses proper synchronization with its counterpart FastPipedInputStream.
