Constructor. | SetAction | ||
| addEventListener(type:String, listener:Function, useCapture:Boolean = false, priority:int = 0, useWeakReference:Boolean = false):void
Registra un oggetto listener di eventi con un oggetto EventDispatcher, in modo che il listener riceva la notifica di un evento. | EventDispatcher | |
|
Captures the current values of the relevant properties
on the effect's targets and saves them as end values. | Effect | |
|
Captures the current values of the relevant properties
of an additional set of targets
Flex uses this function when a data change
effect is run.
| Effect | |
|
Captures the current values of the relevant properties
on the effect's targets. | Effect | |
|
Creates a single effect instance and initializes it. | Effect | |
|
Takes an Array of target objects and invokes the
createInstance() method on each target. | Effect | |
|
Removes event listeners from an instance
and removes it from the list of instances. | Effect | |
|
Invia un evento nel flusso di eventi. | EventDispatcher | |
|
Interrupts an effect that is currently playing,
and jumps immediately to the end of the effect. | Effect | |
|
Returns an Array of Strings, where each String is the name
of a property changed by this effect. | Effect | |
|
Verifica se per l'oggetto EventDispatcher sono presenti listener registrati per un tipo specifico di evento. | EventDispatcher | |
|
Indica se per un oggetto è definita una proprietà specifica. | Object | |
|
Indica se un'istanza della classe Object si trova nella catena di prototipi dell'oggetto specificato come parametro. | Object | |
|
Pauses the effect until you call the resume() method. | Effect | |
|
Begins playing the effect. | Effect | |
|
Indica se la proprietà specificata esiste ed è enumerabile. | Object | |
|
Rimuove un listener dall'oggetto EventDispatcher. | EventDispatcher | |
|
Resumes the effect after it has been paused
by a call to the pause() method. | Effect | |
|
Plays the effect in reverse, if the effect is currently playing,
starting from the current position of the effect. | Effect | |
|
Imposta la disponibilità di una proprietà dinamica per le operazioni cicliche. | Object | |
|
Stops the effect, leaving the effect targets in their current state. | Effect | |
|
Restituisce la rappresentazione in formato stringa di questo oggetto, formattato in base alle convenzioni specifiche per le versioni localizzate. | Object | |
|
Restituisce la rappresentazione in formato stringa dell'oggetto specificato. | Object | |
|
Restituisce il valore di base dell'oggetto specificato. | Object | |
