All Implemented Interfaces:

RepositionableStream, Closeable

public class ByteBufferInputStream
extends MeasurableInputStream
implements RepositionableStream

A bridge between byte buffers and input streams.

The main usefulness of this class is that of making it possible creating input streams that are really based on a MappedByteBuffer.
