Method Detail

exceptionCaught

public void exceptionCaught(IoSession session,
                            java.lang.Throwable cause)
                     throws java.lang.Exception

Description copied from interface: IoHandler

Invoked when any exception is thrown by user IoHandler implementation or by MINA. If cause is an instance of IOException, MINA will close the connection automatically.

Specified by:

exceptionCaught in interface IoHandler

Overrides:

exceptionCaught in class IoHandlerAdapter

Throws:

java.lang.Exception

messageReceived

public void messageReceived(IoSession session,
                            java.lang.Object message)
                     throws java.lang.Exception

Description copied from interface: IoHandler

Invoked when a message is received.

Specified by:

messageReceived in interface IoHandler

Overrides:

messageReceived in class IoHandlerAdapter

Throws:

java.lang.Exception

messageSent

public void messageSent(IoSession session,
                        java.lang.Object message)
                 throws java.lang.Exception

Description copied from interface: IoHandler

Invoked when a message written by IoSession.write(Object) is sent out.

Specified by:

messageSent in interface IoHandler

Overrides:

messageSent in class IoHandlerAdapter

Throws:

java.lang.Exception

sessionClosed

public void sessionClosed(IoSession session)
                   throws java.lang.Exception

Description copied from interface: IoHandler

Invoked when a connection is closed.

Specified by:

sessionClosed in interface IoHandler

Overrides:

sessionClosed in class IoHandlerAdapter

Throws:

java.lang.Exception

sessionCreated

public void sessionCreated(IoSession session)
                    throws java.lang.Exception

Description copied from interface: IoHandler

Invoked from an I/O processor thread when a new connection has been created. Because this method is supposed to be called from the same thread that handles I/O of multiple sessions, please implement this method to perform tasks that consumes minimal amount of time such as socket parameter and user-defined session attribute initialization.

Specified by:

sessionCreated in interface IoHandler

Overrides:

sessionCreated in class IoHandlerAdapter

Throws:

java.lang.Exception

sessionIdle

public void sessionIdle(IoSession session,
                        IdleStatus status)
                 throws java.lang.Exception

Description copied from interface: IoHandler

Invoked with the related IdleStatus when a connection becomes idle. This method is not invoked if the transport type is UDP; it's a known bug, and will be fixed in 2.0.

Specified by:

sessionIdle in interface IoHandler

Overrides:

sessionIdle in class IoHandlerAdapter

Throws:

java.lang.Exception

sessionOpened

public void sessionOpened(IoSession session)
                   throws java.lang.Exception

Description copied from interface: IoHandler

Invoked when a connection has been opened. This method is invoked after IoHandler.sessionCreated(IoSession). The biggest difference from IoHandler.sessionCreated(IoSession) is that it's invoked from other thread than an I/O processor thread once thread model is configured properly.

Specified by:

sessionOpened in interface IoHandler

Overrides:

sessionOpened in class IoHandlerAdapter

Throws:

java.lang.Exception

main

public static void main(java.lang.String[] args)
