Class NetworkListener

source code

object --+
         |
        NetworkListener

Network listener abstract class. Forwards data to multiple subscribed observers and can have a single callback to get data forwarded to.

Methods that MUST be implemented by an inheriting class:

observers and the data callback run() method MUST call self.forward_data(data, addr). Note that addr is optional.

Instance Methods [hide private]
 
__init__(self, observers=[], data_callback=None)
Constructor for the NetworkListener class		 source code
 
forward_data(self, data, addr='')
Forwards data to the subscribed observers and to the data callback.		 source code
 
subscribe(self, observer)
Subscribes an observer for data forwarding.		 source code
 
is_listening(self)
Returns whether this network listener is listening (already started with start()).		 source code
 
is_running(self)
Same as is_listening().		 source code
 
start(self) source code
 
stop(self) source code
 
_cleanup(self)
Removes references to other classes, in order to make GC easier		 source code
 
destroy(self) source code
