Core Classes
====================

The following classes are useful for advanced use of PyPubSub: 

- pubsub.core.Listener
- pubsub.core.TopicObj
- pubsub.core.TopicManager
- pubsub.core.Publisher

It is not typically necessary to know about or use these: the pub module instantiates a 
default Publisher, which contains a TopicManager, which generates a Topic object
for every topic used. The Publisher instance returns a Listener instance from subscribe, 
wrapping the given callable with pubsub-relevant meta-data about the callable. 

.. note:: The following subsections provide the documentation for those classes 
    when the kwargs messaging protocol is used (the default). When arg1 is used, 
    the replace any ``**kwargs`` by ``data``.
