public class ByteBufferOutputStream

extends java.io.ByteArrayOutputStream

An in-memory java.io.OutputStream that supports a backing java.nio.ByteBuffer.

Implementation Note

The contents of the ByteBuffer returned by instances of this class are not protected against further modifications (for example, by invoking the reset method). Similarly, modifications to the returned ByteBuffer imply modifications to the contents of this instance.

It also goes without saying that the behavior of this class is undefined under concurrent access.
