Class: WKcSignaler

Methods

addObserver(p_type, p_observer) → {WKcSignaler}

Adds an observer for events of type p_type.

Parameters:

Name	Type	Description
p_type	String | int	The type of the event signaled. Usually a property value of the object $wk$.$E$. The pseudo type "*" denotes that all events are signaled to the observer.
p_observer	function	A callback function. The parameter list of that function depends on the signaler that dispatches events of type p_type

Type

WKcSignaler

addObservers(p_observers) → {WKcSignaler}

Simultaniously adds observers for several events.

Parameters:

Name	Type	Description
p_observers	Object	A hash map. Each key denotes an event type. The values must contain the observer functions to be called.

removeObserver(p_type, p_observer) → {WKcSignaler}

Removes an observer for events of type p_type.

Parameters:

Name	Type	Description
p_type	String | int	The type of the event signaled. Usually a property value of the object $wk$.$E$. The pseudo type "*" denotes that all events are signaled to the observer.

removeObservers(p_observers) → {WKcSignaler}

Parameters:

Name	Type	Description
p_observers	Object	A hash map. Each key denotes an event type. The values must contain the observer functions to be called.

Type

WKcSignaler

signal(p_event, arguments) → {WKcSignaler}

Signals to all current observers that an event has occured. Signals an event of type p_event or p_event.type to all observers that are currently listening on events of this type. As signaler object that dispatches this event acts either p_event.signaler (if that property exists) or this.

Parameters:

Name	Type	Description
p_event	String | int | Object	The event to be signaled. Usually a property value of the object $wk$.$E$, which denotes an event type. If p_event is an object, p_event.type is used as the type of the event to be signaled.
arguments	Array	Arbitrary further arguments that are passed to the observer functions (together with p_event).
