Interface ProtocolEncoder

All Known Implementing Classes:
ObjectSerializationEncoder, ProtocolEncoderAdapter, SynchronizedProtocolEncoder, TextLineEncoder

public interface ProtocolEncoder

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 by calling ProtocolEncoderOutput.write(ByteBuffer).

Please refer to TextLineEncoder example.


Method Summary
 void dispose(IoSession session)
          Releases all resources related with this encoder.
 void encode(IoSession session, java.lang.Object message, ProtocolEncoderOutput out)
          Encodes higher-level message objects into binary or protocol-specific data.
 

Method Detail

encode

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

dispose

void dispose(IoSession session)
             throws java.lang.Exception
Releases all resources related with this encoder.

Throws:
java.lang.Exception - if failed to dispose all resources
