NAME
MooseX::Event::Role - A Node style event Role for Moose
VERSION
version v0.2.0
DESCRIPTION
This is the role that MooseX::Event extends your class with. All classes using MooseX::Event will have these methods, attributes and events.
EVENTS
new_listener( Str $event, CodeRef $listener )
Called when a listener is added. $event is the name of the event being listened to, and $listener is the listener being installed.
ATTRIBUTES
our Str $.current_event is rw
This is the name of the current event being triggered, or undef if no event is being triggered.
METHODS
our method event_exists( Str $event ) returns Bool
Returns true if $event is a valid event name for this class.
our method on( Str $event, CodeRef $listener ) returns CodeRef
Registers $listener as a listener on $event. When $event is emitted ALL registered listeners are executed.
Returns the listener coderef.
our method once( Str $event, CodeRef $listener ) returns CodeRef
Registers $listener as a listener on $event. Event listeners registered via once will emit only once.
Returns the listener coderef.
our method emit( Str $event, Array[Any] *@args )
Normally called within the class using the MooseX::Event role. This calls all of the registered listeners on $event with @args.
If you're using coroutines then each listener will get its own thread and emit will cede before returning.
our method remove_all_listeners( Str $event )
Removes all listeners for $event
our method remove_listener( Str $event, CodeRef $listener )
Removes $listener from $event
