Class EventHandler

        EventHandler

Creates an event handler for ecore events.

This class represents an event handler that will call the given func when the event of given type happens. The function will be passed any extra parameters given to constructor.

When the handler func is called, it must return a value of either True or False (remember that Python returns None if no value is explicitly returned and None evaluates to False). If it returns True, it will be called again for the next event, or if it returns False it will be deleted automatically making any references/handles for it invalid.

Handlers should be stopped/deleted by means of delete() or returning False from func, otherwise they'll continue alive, even if the current python context delete it's reference to it.
