Method Detail

handleMessage

void handleMessage(Connection connection,
                   InputStream dataStream)
            throws IOException

Handle a message.

Parameters:

connection - the connection to the remote side

dataStream - the message bytes

Throws:

IOException - if an I/O error occurs

handleShutdown

void handleShutdown(Connection connection)
             throws IOException

Handle the end-of-input condition. The write side will still be writable.

Parameters:

connection - the connection to the remote side

Throws:

IOException - if an I/O error occurs

handleFailure

void handleFailure(Connection connection,
                   IOException e)
            throws IOException

Handle an input failure condition. The write side is unlikely to be writable. When a failure is encountered, the socket should usually be Connection.close()d.

Parameters:

connection - the connection to the remote side

e - the read error received

Throws:

IOException - if an I/O error occurs

handleFinished

void handleFinished(Connection connection)
             throws IOException

Handle the condition where a connection is completely finished (both reads and writes). This is where any reconnect logic should live.

Parameters:

connection - the connection that ended

Throws:

IOException - if an I/O error occurs
