Method Detail

timeout

public void timeout(IoSession session,
           ProtocolDecoderOutput out)
             throws Exception

Description copied from class: TimedEndDecoder

Handle the timeout situation

Specified by:

timeout in class TimedEndDecoder

Parameters:

session - the session for which the timeout occurred

out - the output

Throws:

Exception

decode

public void decode(IoSession session,
          IoBuffer in,
          ProtocolDecoderOutput out)
            throws Exception

Description copied from interface: ProtocolDecoder

Decodes binary or protocol-specific content into higher-level message objects. MINA invokes ProtocolDecoder.decode(IoSession, IoBuffer, ProtocolDecoderOutput) method with read data, and then the decoder implementation puts decoded messages into ProtocolDecoderOutput.

Throws:

Exception - if the read data violated protocol specification
