Interface ProtocolEncoder

All Known Implementing Classes:
DemuxingProtocolEncoder, ObjectSerializationEncoder, PrefixedStringEncoder, 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 messages (typically IoBuffers) into ProtocolEncoderOutput by calling ProtocolEncoderOutput.write(Object).

Please refer to TextLineEncoder example.

Method Detail

encode

void encode(IoSession session,
            Object 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 messages (typically IoBuffers) into ProtocolEncoderOutput.

Throws:
Exception - if the message violated protocol specification

dispose

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

Throws:
Exception - if failed to dispose all resources
