Class FastPipedInputStream

java.lang.Object
  java.io.InputStream
      org.jvnet.hudson.ec2.launcher.FastPipedInputStream

All Implemented Interfaces:

java.io.Closeable

public class FastPipedInputStream
extends java.io.InputStream

This class is equivalent to java.io.PipedInputStream. 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 FastPipedOutputStream.
