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

Encodes higher-level message objects into binary or protocol-specific data. MINA invokes 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.

Parameters:

session - The current session

message - The message to encode

out - The instance of ProtocolEncoderOutput that will receive the encoded message

Throws:

Exception - if the message violated protocol specification
