Removing Listeners

Listener objects can be removed when the application is no longer interested in receiving real-time updates. A listener (or all of them) should be removed from the same event handler object which they were added to. The following listener removal APIs are available:

Removing all listeners

The method removes all registered listeners for the update event:

eventHandler.RemoveUpdateListeners();

The method below removes all listeners which process events for a specific where clause. The value of the whereClause argument must be the same as one in the AddUpdateListener method:

eventHandler.RemoveUpdateListeners( string whereClause );

Removing a specific listener

This method removes a listener identified by a delegate implementation:

eventHandler.RemoveUpdateListener( ObjectUpdated<T> objectUpdated );
