Class DemuxingProtocolEncoder

java.lang.Object

org.apache.mina.filter.codec.demux.DemuxingProtocolEncoder

All Implemented Interfaces:

ProtocolEncoder

public class DemuxingProtocolEncoder
extends Object
implements ProtocolEncoder

A composite ProtocolEncoder that demultiplexes incoming message encoding requests into an appropriate MessageEncoder.

Disposing resources acquired by MessageEncoder

Override dispose(IoSession) method. Please don't forget to call super.dispose().

public <T> void addMessageEncoder(Iterable<Class<? extends T>> messageTypes,

encode

public void encode(IoSession session,
          Object message,
          ProtocolEncoderOutput out)
            throws Exception

Encodes higher-level message objects into binary or protocol-specific data. MINA invokes ProtocolEncoder.encode(IoSession, Object, ProtocolEncoderOutput) method with message which is popped from the session write queue, and then the encoder implementation puts encoded messages (typically IoBuffers) into ProtocolEncoderOutput.

Specified by:

encode in interface ProtocolEncoder

Throws:

Exception - if the message violated protocol specification

findEncoder

protected MessageEncoder<Object> findEncoder(org.apache.mina.filter.codec.demux.DemuxingProtocolEncoder.State state,
                                 Class<?> type)

dispose

public void dispose(IoSession session)
             throws Exception

Releases all resources related with this encoder.

Specified by:

dispose in interface ProtocolEncoder

Throws:

Exception - if failed to dispose all resources
