virtual void	ndOnCreateConn (NDChannel *chan, NDConn *conn)=0
	This callback is each time a new conn is created, i.e. in response to new incoming client connection.
virtual void	ndOnConnTimeout (NDChannel *chan, NDConn *conn)=0
	This callback is each time a conn times out.
virtual void	ndOnConnClose (NDChannel *chan, NDConn *conn)=0
	This callback is each time a conn is closed.
virtual void	ndOnConnReconnect (NDChannel *chan, NDConn *conn)=0
	This callback is each time a conn is reconnected.
virtual void	ndOnDeleteConn (NDChannel *chan, NDConn *conn)=0
	This callback is each time a conn is deleted.

Detailed Description

Provides an interface for responding to connection-related events, such as open, close, etc.

To use this class, create a subclass which implements all the functions in this interface. Then, register the handler by calling NDCore::registerConnHandler.

		NDConn *	conn
	)			[pure virtual]

Parameters:

	chan	the channel the closed conn belongs to
	conn	the conn which closed

NDConnHandler::ndOnConnReconnect	(	NDChannel *	chan,
		NDConn *	conn
	)			[pure virtual]

Parameters:

	chan	the channel the reconnected conn belongs to
	conn	the conn which reconnected

NDConnHandler::ndOnConnTimeout	(	NDChannel *	chan,
		NDConn *	conn
	)			[pure virtual]

Parameters:

	chan	the channel the timed-out conn belongs to
	conn	the conn which timed out

NDConnHandler::ndOnCreateConn	(	NDChannel *	chan,
		NDConn *	conn
	)			[pure virtual]

Parameters:

	chan	the channel on which the new conn was created
	conn	the new conn itself

NDConnHandler::ndOnDeleteConn	(	NDChannel *	chan,
		NDConn *	conn
	)			[pure virtual]

Parameters:

	chan	the channel the deleted conn belongs to
	conn	the conn which was deleted (the conn is still valid until this callback returns)
