NAME

       Padre::Role::PubSub - A simple event publish/subscriber role

DESCRIPTION

       This class allows the addition of simple publish/subscribe behaviour to an arbitrary class.

METHODS

   subscribe
         $publisher->subscriber( $object, {
             my_event_one => 'my_handler_method',
             my_event_two => 'my_handler_method',
         } );

       The <subscriber> method lets you register an object for callbacks to a particular set of method for
       various named events.

       Returns true, or throws an exception if any of the parameters are invalid.

   unsubscribe
         $publisher->unsubscribe($subscriber);

       The "unsubscribe" method removes all event registrations for a particular object.

       Returns true.

   publish
         $publisher->publish("my_event_one", "param1", "param2");

       The "publish" method is called on the published to emit a particular named event.

       It calls any registered event handlers in sequence, ignoring exceptions.

       Returns true, or throws an exception if the event name is invalid.
