void encode(IoSession session,
            java.lang.Object message,
            ProtocolEncoderOutput out)
     throws java.lang.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 ByteBuffers into ProtocolEncoderOutput.
    
    Throws:
    
    java.lang.Exception - if the message violated protocol specification
