java.lang.Object
  java.io.OutputStream
      org.apache.struts2.util.FastByteArrayOutputStream

All Implemented Interfaces:

java.io.Closeable, java.io.Flushable

public class FastByteArrayOutputStream
extends java.io.OutputStream

A speedy implementation of ByteArrayOutputStream. It's not synchronized, and it does not copy buffers when it's expanded. There's also no copying of the internal buffer if it's contents is extracted with the writeTo(stream) method.
