All Implemented Interfaces:

Closeable, Flushable, AutoCloseable

public class FastByteArrayOutputStream
extends 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.
