Hello everyone.
I'm looking for some explanation on event handling in POX.
Lets say that i have 2 components registered in core with names Component_1 and
Component_2. Component_1 raises some event called Event_1.
I want to handle some events in Component_2 both from core.openflow and from
core.Component_1.
How should i name the handler methods in Component_2 and how should i register
the listeners? Is the following example correct?
In Component_2:
__init__(self):
core.Component_1.addListeners(self)
core.openflow.addListeners(self)
def _handle_openflow_ConnectionUp(self):
….
def _handle_Component_1_Event_1(self):
….
Secondly, i only want a component to start handling events afar having received
a notification from another component. Can i add the listeners only after i
have "caught" an event? Something like the following:
__init__(self):
core.Component_1.addListeners(self)
def _handle_Component_1_Event_1(self):
core.openflow.addListeners(self)
Third, can someone explain to me what the core.listen_to_dependencies does?
Thank you in advance,
John
