Method Detail

dispose

public void dispose(IoSession session)
             throws Exception

Description copied from interface: ProtocolEncoder

Releases all resources related with this encoder.

Specified by:

dispose in interface ProtocolEncoder

Throws:

Exception - if failed to dispose all resources

createMessage

protected IoBuffer createMessage(IoSession session,
                     byte command,
                     boolean longMessage)

encode

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

Description copied from interface: ProtocolEncoder

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
