public class FastByteArrayOutputStream

extends ByteArrayOutputStream

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.
