public class ByteBufferByteReader extends Object
ByteReader
that wraps a
ByteBuffer
.
This class is not threadsafe. It is not safe to pass an instance of this class
to multiple threads. It is not safe to pass an instance of this class to multiple users even
if in the same thread. It is not safe to give the same ByteBuffer to multiple instances
of this class.EOF
