Detailed Description

IO Handler class (interface)

Member Function Documentation

virtual void esnlib::IoHandler::OnConnect ( SessionPtr  session )

pure virtual

The callback function for the Connect event

Parameters

session

Current session

Implemented in esnlib::MessageHandler, and esnlib::StringHandler.

virtual void esnlib::IoHandler::OnDisconnect ( SessionPtr  session )

pure virtual

The callback function for the Disconnect event

Parameters

session

Current session

Implemented in esnlib::MessageHandler, and esnlib::StringHandler.

virtual void esnlib::IoHandler::OnError ( SessionPtr  session, int  errorType, int  errorCode, const std::string &  errorMsg  )

pure virtual

The callback function for the Error event

Parameters

session	Current session
errorType	The error type (1 for read error, 2 for write error, 0 for connect error)
errorCode	The error code (if error type == 0 and error code == 0, that means connect timeout)
errorMsg	The error message

Implemented in esnlib::MessageHandler, and esnlib::StringHandler.

virtual void esnlib::IoHandler::OnIdle ( SessionPtr  session, int  idleType  )

pure virtual

The callback function for the Idle event

Parameters

session	Current session
idleType	The idle type (1 for read idle, 2 for write idle, 0 for both)

Implemented in esnlib::MessageHandler, and esnlib::StringHandler.

virtual int esnlib::IoHandler::OnRead ( SessionPtr  session, IoBufferPtr  data  )

pure virtual

The callback function for the Read event

Parameters

session	Current session
data	The buffer pointer of the useful data read

Returns

The flags of the event processing: 1 = async, 2 = concurrent, 3 = both 1 and 2

Implemented in esnlib::MessageHandler, and esnlib::StringHandler.

virtual int esnlib::IoHandler::OnWrite ( SessionPtr  session, IoBufferPtr  data  )

pure virtual

The callback function for the Write event

Parameters

session	Current session
data	The buffer pointer of the data written

Returns

The flags of the event processing: 1 = async, 2 = concurrent, 3 = both 1 and 2

Implemented in esnlib::MessageHandler, and esnlib::StringHandler.
