__construct ( Container $container )	Public constructor
attach ( Observer $observer ) : Dispatcher	Attaches an observer to the object
chainHandle ( string $event, array $args = [] ) : mixed	Asks each observer to handle an event based on the provided arguments. The first observer to return a non-null result wins. This is a very simplistic implementation of the Chain of Command pattern.
detach ( Observer $observer ) : Dispatcher	Detaches an observer from the object
getContainer ( ) : Container	Returns the container this event dispatcher is attached to
getObserverByClass ( string $className ) : null \| Observer	Returns an observer attached to this behaviours dispatcher by its class name
hasObserver ( Observer $observer ) : boolean	Is an observer object already registered with this dispatcher?
hasObserverClass ( string $className ) : boolean	Is there an observer of the specified class already registered with this dispatcher?
trigger ( string $event, array $args = [] ) : array	Triggers an event in the attached observers
