Description:
 def handler(*names, **kwargs):
 """Creates an Event Handler This decorator can be applied to methods of classes derived from :class:`circuits.core.components.BaseComponent`. It marks the method as a handler for the events passed as arguments to the ``@handler`` decorator. The events are specified by their name. The decorated method's arguments must match the arguments passed to the :class:`circuits.core.events.Event` on creation. Optionally, the method may have an additional first argument named *event*. If declared, the event object that caused the handler to be invoked is assigned to it. By default, the handler is invoked by the component's root :class:`~.manager.Manager` for events that are propagated on the channel determined by the BaseComponent's *channel* attribute. This may be overridden by specifying a different channel as a keyword Keyword argument ``priority`` influences the order in which handlers for a specific event are invoked. The higher the priority, the earlier the handler is executed. If you want to override a handler defined in a base class of your component, you must specify ``override=True``, else your method becomes an additional handler for the event. **Return value** Normally, the results returned by the handlers for an event are simply collected in the :class:`circuits.core.events.Event`'s :attr:`value` attribute. As a special case, a handler may return a :class:`types.GeneratorType`. This signals to the dispatcher that the handler isn't ready to deliver a result yet. Rather, it has interrupted it's execution with a ``yield None`` statement, thus preserving its current execution state. The dispatcher saves the returned generator object as a task. All tasks are reexamined (i.e. their :meth:`next()` method is invoked) when the pending events have been executed. This feature avoids an unnecessarily complicated chaining of event handlers. Imagine a handler A that needs the results from firing an event E in order to complete. Then without this feature, the final action of A would be to fire event E, and another handler for an event ``SuccessE`` would be required to complete handler A's operation, now having the result from invoking E available (actually it's even a bit more complicated). Using this "suspend" feature, the handler simply fires event E and then yields ``None`` until e.g. it finds a result in E's :attr:`value` attribute. For the simplest scenario, there even is a utility method :meth:`circuits.core.manager.Manager.callEvent` that combines firing and waiting. """
