Class BufferOutputStream

java.lang.Object

java.io.OutputStream

org.fusesource.hawtbuf.BufferOutputStream

All Implemented Interfaces:

java.io.Closeable, java.io.Flushable, java.lang.AutoCloseable

public final class BufferOutputStream
extends java.io.OutputStream

Very similar to the java.io.ByteArrayOutputStream but this version is not thread safe and the resulting data is returned in a Buffer to avoid an extra byte[] allocation. It also does not re-grow it's internal buffer.
