Method Detail

encode

public void encode(IoSession session,
                   T message,
                   ProtocolEncoderOutput out)
            throws java.lang.Exception

Description copied from interface: MessageEncoder

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

Specified by:

encode in interface MessageEncoder<T extends AbstractMessage>

Throws:

java.lang.Exception - if the message violated protocol specification

encodeBody

protected abstract void encodeBody(IoSession session,
                                   T message,
                                   IoBuffer out)
