[confluence]

Page Edited : MINA : IoHandler IoHandler has been edited by Ashish Paliwal (Dec 12, 2008). Change summary: Added methods (View changes) Content: Introduction Handles all I/O events fired by MINA. The interface is hub of all activities done at the end of the Filter Chain. IoHandler has following functions sessionCreated sessionOpened sessionClosed sessionIdle exceptionCaught messageReceived messageSent sessionCreated Event Session Created event is fired when a new connection is created. For TCP its the result of connection accept, and for UDP this is generated when a UDP packet is received. This function can be used to initialize session attributes, and perform one time activities for a particular connection. This function is invoked from the I/O processor thread context, hence should be implemented in a way that it consumes minimal amount of time, as the same thread handles multiple sessions. sessionOpened Event Session opened event is invoked when a connection is opened. Its is always called after sessionCreated event. If a thread model is configured, this function is called in a thread other than the I/O processor thread. sessionClosed Event Session Closed event is closed, when a session is closed. Session cleaning activities like cash cleanup can be performed here. sessionIdle Event Session Idle event is fired when a session becomes idle. This function is not invoked for UDP transport. exceptionCaught Event This functions is called, when an Exception is thrown by user code or by MINA. The connection is closed, if its an IOException. messageReceived Event Message Received event is fired whenever a message is received. This is where the most of the processing of an application happens. You need to take care of all the message type you expect here. messageSent Event Message Sent event is fired, whenever a message aka response has been sent(calling IoSession.write()).
