  org.apache.mina.core.service.IoHandlerAdapter
      org.apache.mina.handler.stream.StreamIoHandler

All Implemented Interfaces:

IoHandler

public abstract class StreamIoHandler
extends IoHandlerAdapter

A IoHandler that adapts asynchronous MINA events to stream I/O.

Please extend this class and implement processStreamIo(IoSession, InputStream, OutputStream) to execute your stream I/O logic; please note that you must forward the process request to other thread or thread pool.
