customFilter | 속성 |
customFilter:mx.effects:EffectTargetFilter
언어 버전: | ActionScript 3.0 |
제품 버전: | Flex 3 |
런타임 버전: | Flash Player 9, AIR 1.1 |
Specifies a custom filter object, of type EffectTargetFilter, used by the effect to determine the targets on which to play the effect.
Target filtering is only performed if you call the
captureStartValues()
method before playing the effect.
Flex automatically calls the captureStartValues()
method
when the effect is part of a transition.
Use the filter
property for simple filtering.
If the customFilter
property is non-null,
the filter
property is ignored.

duration | 속성 |
duration:Number
언어 버전: | ActionScript 3.0 |
제품 버전: | Flex 3 |
런타임 버전: | Flash Player 9, AIR 1.1 |
Duration of the effect in milliseconds.
In a Parallel or Sequence effect, the duration
property sets the duration of each effect.
For example, if a Sequence effect has its duration
property set to 3000, each effect in the Sequence takes 3000 ms
to play.
For a repeated effect, the duration
property
specifies the duration of a single instance of the effect.
Therefore, if an effect has a duration
property
set to 2000, and a repeatCount
property set to 3,
the effect takes a total of 6000 ms (6 seconds) to play.

A flag containing true
if the end values
of an effect have already been determined,
or false
if they should be acquired from the
current properties of the effect targets when the effect runs.
This property is required by data effects because the sequence
of setting up the data effects, such as DefaultListEffect
and DefaultTileListEffect, is more complicated than for
normal effects.

Specifies an algorithm for filtering targets for an effect.
A value of null
specifies no filtering.
Target filtering is only performed if you call the
captureStartValues()
method before playing the effect.
Flex automatically calls the captureStartValues()
method
when the effect is part of a transition, or part of a data effect
for a list-based control.
Use this property for simple filtering.
Use the customFilter
property for more complex filtering.
If the customFilter
property has a non-null value,
this property is ignored.
You can use the following values for the filter
property:
- A value of
"add"
plays the effect on any targets that are added as a child to a container. - A value of
"addItem"

applyValueToTarget | () | 메서드 |
protected function applyValueToTarget(target:Object, property:String, value:*, props:Object):void
언어 버전: | ActionScript 3.0 |
제품 버전: | Flex 3 |
런타임 버전: | Flash Player 9, AIR 1.1 |
Used internally by the Effect infrastructure.
If captureStartValues()
has been called,
then when Flex calls the play()
method, it uses this function
to set the targets back to the starting state.
The default behavior is to take the value captured
using the getValueFromTarget()
method
and set it directly on the target's property. For example:
target[property] = value;
Only override this method if you need to apply
the captured values in a different way.
Note that style properties of a target are set
using a different mechanism.
Use the relevantStyles
property to specify
which style properties to capture and apply.
매개 변수
target:Object — The effect target.
| |
property:String — The target property.
| |
value:* — The value of the property.

public function captureStartValues():void
언어 버전: | ActionScript 3.0 |
제품 버전: | Flex 3 |
런타임 버전: | Flash Player 9, AIR 1.1 |
Captures the current values of the relevant properties
on the effect's targets.
Flex automatically calls the captureStartValues()
method when the effect is part of a transition.
Use this function when you want the effect to figure out the start and end values of the effect. The proper usage of this function is to use it in the following steps:
- Call the
captureStartValues()
method. The effect captures the starting effect values. - Make changes to your effect targets, such as adding/removing children, altering properties, changing location, or changing dimensions.
- Call the
play()
method. The effect captures the end values. This function populates theEffectInstance.propertyChanges
property for each effect instance created by this effect. Effect developers can use thepropertyChanges
property to retrieve the start and end values for their effect.
createInstance | () | 메서드 |
public function createInstance(target:Object = null):IEffectInstance
언어 버전: | ActionScript 3.0 |
제품 버전: | Flex 3 |
런타임 버전: | Flash Player 9, AIR 1.1 |
Creates a single effect instance and initializes it.
Use this method instead of the play()
method
to manipulate the effect instance properties
before the effect instance plays.
The effect instance is created with the type
specified in the instanceClass
property.
It is then initialized using the initInstance()
method.
If the instance was created by the EffectManager
(when the effect is triggered by an effect trigger),
the effect is further initialized by a call to the
EffectInstance.initEffect()
method.
Calling the createInstance()
method
does not play the effect.
Call the startEffect()
method
on the returned effect instance.
This function is automatically called by the
Effect.play()
method.

Every subclass of Effect must implement this method. The EffectManager uses this method to ensure that no two effects are trying to animate the same property of the same object at the same time.
반환값Array — An Array of Strings specifying the names of the
properties modified by this effect.

getValueFromTarget | () | 메서드 |
protected function getValueFromTarget(target:Object, property:String):*
언어 버전: | ActionScript 3.0 |
제품 버전: | Flex 3 |
런타임 버전: | Flash Player 9, AIR 1.1 |
Called by the captureStartValues()
method to get the value
of a property from the target.
This function should only be called internally
by the effects framework.
The default behavior is to simply return target[property]
.
Effect developers can override this function
if you need a different behavior.
매개 변수
target:Object — The effect target.
| |
property:String — The target property.
|
* — The value of the target property.
|
initInstance | () | 메서드 |
protected function initInstance(instance:IEffectInstance):void
언어 버전: | ActionScript 3.0 |
제품 버전: | Flex 3 |
런타임 버전: | Flash Player 9, AIR 1.1 |
Copies properties of the effect to the effect instance.
Flex calls this method from the Effect.createInstance()
method; you do not have to call it yourself.
When you create a custom effect, override this method to
copy properties from the Effect class to the effect instance class.
In your override, call super.initInstance()
.
매개 변수
instance:IEffectInstance — The effect instance to initialize.

기타 예제
pause | () | 메서드 |
public function pause():void
언어 버전: | ActionScript 3.0 |
제품 버전: | Flex 3 |
런타임 버전: | Flash Player 9, AIR 1.1 |
Pauses the effect until you call the resume()
method.
play | () | 메서드 |
public function play(targets:Array = null, playReversedFromEnd:Boolean = false):Array
언어 버전: | ActionScript 3.0 |
제품 버전: | Flex 3 |
런타임 버전: | Flash Player 9, AIR 1.1 |
Begins playing the effect.
You typically call the end()
method
before you call the play()
method
to ensure that any previous instance of the effect
has ended before you start a new one.
All subclasses must implement this method.
매개 변수
targets:Array (default = null ) — Array of target objects on which to play this effect.
If this parameter is specified, then the effect's targets
property is not used.
| |
playReversedFromEnd:Boolean (default = false ) — If true ,
play the effect backwards.
|
Array — Array of EffectInstance objects, one per target,
for the effect.
|
resume | () | 메서드 |
public function resume():void
언어 버전: | ActionScript 3.0 |
제품 버전: | Flex 3 |
런타임 버전: | Flash Player 9, AIR 1.1 |
Resumes the effect after it has been paused
by a call to the pause()
method.
reverse | () | 메서드 |
public function reverse():void
언어 버전: | ActionScript 3.0 |
제품 버전: | Flex 3 |
런타임 버전: | Flash Player 9, AIR 1.1 |
Plays the effect in reverse, if the effect is currently playing, starting from the current position of the effect.
stop | () | 메서드 |
public function stop():void
언어 버전: | ActionScript 3.0 |
제품 버전: | Flex 3 |
런타임 버전: | Flash Player 9, AIR 1.1 |
Stops the effect, leaving the effect targets in their current state.
Unlike a call to the pause()
method,
you cannot call the resume()
method after calling
the stop()
method.
However, you can call the play()
method to restart the effect.
The effect instance dispatches an effectEnd
event
when you call this method as part of ending the effect.
For mask effects, the mask is not removed automatically when the effect is stopped. Running further mask effects on the same target(s) without first removing the mask can produce unexpected results.
effectEnd | 이벤트 |
mx.events.EffectEvent
속성 EffectEvent.type =
mx.events.EffectEvent.EFFECT_END
언어 버전: | ActionScript 3.0 |
제품 버전: | Flex 3 |
런타임 버전: | Flash Player 9, AIR 1.1 |
Dispatched when one of the effect's instances finishes playing,
either when the instance finishes playing or when the effect
is interrupted by a call to the end()
method.
EffectEvent.EFFECT_END
constant defines the value of the
type
property of the event object for an
effectEnd
event.
The properties of the event object have the following values:
Property | Value |
---|---|
bubbles | false |
cancelable | false |
currentTarget | The Object that defines the
event listener that handles the event. For example, if you use
myButton.addEventListener() to register an event listener,
myButton is the value of the currentTarget . |
effectInstance | The effect instance object for the event. |
target | The Object that dispatched the event;
it is not always the Object listening for the event.
Use the currentTarget property to always access the
Object listening for the event. |
effectStart | 이벤트 |
mx.events.EffectEvent
속성 EffectEvent.type =
mx.events.EffectEvent.EFFECT_START
언어 버전: | ActionScript 3.0 |
제품 버전: | Flex 3 |
런타임 버전: | Flash Player 9, AIR 1.1 |
Dispatched when the effect starts playing.
TheEffectEvent.EFFECT_START
constant defines the value of the
type
property of the event object for an
effectStart
event.
The properties of the event object have the following values:
Property | Value |
---|---|
bubbles | false |
cancelable | false |
currentTarget | The Object that defines the
event listener that handles the event. For example, if you use
myButton.addEventListener() to register an event listener,
myButton is the value of the currentTarget . |
effectInstance | The effect instance object for the event. |
target | The Object that dispatched the event;
it is not always the Object listening for the event.
Use the currentTarget property to always access the
Object listening for the event. |
effectStop | 이벤트 |
mx.events.EffectEvent
속성 EffectEvent.type =
mx.events.EffectEvent.EFFECT_STOP
언어 버전: | ActionScript 3.0 |
제품 버전: | Flex 3 |
런타임 버전: | Flash Player 9, AIR 1.1 |
Dispatched when the effect has been stopped,
which only occurs when the effect is
interrupted by a call to the stop()
method.
The EFFECT_END event is also dispatched to indicate that
the effect has ended. This extra event is sent first, as an
indicator to listeners that the effect did not reach its
end state.
EffectEvent.EFFECT_STOP
constant defines the value of the
type
property of the event object for an
effectStop
event.
The properties of the event object have the following values:
Property | Value |
---|---|
bubbles | false |
cancelable | false |
currentTarget | The Object that defines the
event listener that handles the event. For example, if you use
myButton.addEventListener() to register an event listener,
myButton is the value of the currentTarget . |
effectInstance | The effect instance object for the event. |
target | The Object that dispatched the event;
it is not always the Object listening for the event.
Use the currentTarget property to always access the
Object listening for the event. |
