Class Detail
adobeDPS-Signal()
[inner] Custom event broadcaster
- inspired by Robert Penner's AS3 Signals.
Field Details
memorize : Boolean
If Signal should keep record of previously dispatched parameters and automatically execute listener during add()/addOnce() if Signal was already dispatched before.
Platforms:
iOS, Android, Windows
active : Boolean
If Signal is active and should broadcast events.

IMPORTANT: Setting this property during a dispatch will only affect the next dispatch, if you want to stop the propagation of a signal use halt() instead.

Platforms:
iOS, Android, Windows
Method Details
has(listener:Function, context:Object) : Boolean
Check if listener was attached to Signal.
Parameters
listener Function
context Object
Returns:
Boolean if Signal has the specified listener.
Platforms:
iOS, Android, Windows
add(listener:Function, listenerContext:Object, priority:Number) : adobeDPS-SignalBinding
Add a listener to the signal.
Parameters
listener Function Signal handler function.
listenerContext Object Context on which listener will be executed (object that should represent the this variable inside listener function).
priority Number The priority level of the event listener. Listeners with higher priority will be executed before listeners with lower priority. Listeners with same priority level will be executed at the same order as they were added. (default = 0)
Returns:
adobeDPS-SignalBinding An Object representing the binding between the Signal and listener.
Platforms:
iOS, Android, Windows
addOnce(listener:Function, listenerContext:Object, priority:Number) : adobeDPS-SignalBinding
Add listener to the signal that should be removed after first execution (will be executed only once).
Parameters
listener Function Signal handler function.
listenerContext Object Context on which listener will be executed (object that should represent the this variable inside listener function).
priority Number The priority level of the event listener. Listeners with higher priority will be executed before listeners with lower priority. Listeners with same priority level will be executed at the same order as they were added. (default = 0)
Returns:
adobeDPS-SignalBinding An Object representing the binding between the Signal and listener.
Platforms:
iOS, Android, Windows
remove(listener:Function, context:Object) : Function
Remove a single listener from the dispatch queue.
Parameters
listener Function Handler function that should be removed.
context Object Execution context (since you can add the same handler multiple times if executing in a different context).
Returns:
Function Listener handler function.
Platforms:
iOS, Android, Windows
removeAll()
Remove all listeners from the Signal.
Platforms:
iOS, Android, Windows
getNumListeners() : Number
Returns:
Number Number of listeners attached to the Signal.
Platforms:
iOS, Android, Windows
halt()
Stop propagation of the event, blocking the dispatch to next listeners on the queue.

IMPORTANT: should be called only during signal dispatch, calling it before/after dispatch won't affect signal broadcast.

See:
adobeDPS-Signal.prototype.disable
Platforms:
iOS, Android, Windows
dispatch(params:...*)
Dispatch/Broadcast Signal to all listeners added to the queue.
Parameters
params ...* Parameters that should be passed to each handler.
Platforms:
iOS, Android, Windows
forget()
Forget memorized arguments.
See:
adobeDPS-Signal.memorize
Platforms:
iOS, Android, Windows
dispose()
Remove all bindings from signal and destroy any reference to external objects (destroy Signal object).

IMPORTANT: calling any method on the signal instance after calling dispose will throw errors.

Platforms:
iOS, Android, Windows
toString() : String
Returns:
String String representation of the object.
Platforms:
iOS, Android, Windows
