actualListeners:Array [read-only]

Language Version:

ActionScript 3.0

Product Version:

Flex 4.5

Runtime Versions:

Flash Player 10.1, AIR 2.5

Contains an Array of listener objects, if any, or the source object. Used to determine which object to notify about the validation result.

Implementation
protected function get actualListeners():Array

actualTrigger

property

actualTrigger:IEventDispatcher [read-only]

Language Version:

ActionScript 3.0

Product Version:

Flex 4.5

Runtime Versions:

Flash Player 10.1, AIR 2.5

Contains the trigger object, if any, or the source object. Used to determine the listener object for the triggerEvent.

Implementation
protected function get actualTrigger():IEventDispatcher

enabled

property

enabled:Boolean

Language Version:

ActionScript 3.0

Product Version:

Flex 4.5

Runtime Versions:

Flash Player 10.1, AIR 2.5

Setting this value to false will stop the validator from performing validation. When a validator is disabled, it dispatches no events, and the validate() method returns null.

The default value is true.

Implementation
public function get enabled():Boolean
public function set enabled(value:Boolean):void

listener

property

listener:Object

Language Version:

ActionScript 3.0

Product Version:

Flex 4.5

Runtime Versions:

Flash Player 10.1, AIR 2.5

Specifies the validation listener.

If you do not specify a listener, Flex uses the value of the source property. After Flex determines the source component, it changes the border color of the component, displays an error message for a failure, or hides any existing error message for a successful validation.

Implementation
public function get listener():Object
public function set listener(value:Object):void

property

property:String

Language Version:

ActionScript 3.0

Product Version:

Flex 4.5

Runtime Versions:

Flash Player 10.1, AIR 2.5

A String specifying the name of the property of the source object that contains the value to validate. The property is optional, but if you specify source, you should set a value for this property as well.

The default value is null.

Implementation
public function get property():String
public function set property(value:String):void

required

property

public var required:Boolean = true

Language Version:

ActionScript 3.0

Product Version:

Flex 4.5

Runtime Versions:

Flash Player 10.1, AIR 2.5

If true, specifies that a missing or empty value causes a validation error.

The default value is true.

requiredFieldError

property

requiredFieldError:String

Language Version:

ActionScript 3.0

Product Version:

Flex 4.5

Runtime Versions:

Flash Player 10.1, AIR 2.5

Error message when a value is missing and the required property is true.

The default value is "This field is required.".

Implementation
public function get requiredFieldError():String
public function set requiredFieldError(value:String):void

resourceManager

property

resourceManager:IResourceManager [read-only]

Language Version:

ActionScript 3.0

Product Version:

Flex 4.5

Runtime Versions:

Flash Player 10.1, AIR 2.5

A reference to the object which manages all of the application's localized resources. This is a singleton instance which implements the IResourceManager interface.

This property can be used as the source for data binding. When this property is modified, it dispatches the unused event.

Implementation
protected function get resourceManager():IResourceManager

source

property

source:Object

Language Version:

ActionScript 3.0

Product Version:

Flex 4.5

Runtime Versions:

Flash Player 10.1, AIR 2.5

Specifies the object containing the property to validate. Set this to an instance of a component or a data model. You use data binding syntax in MXML to specify the value. This property supports dot-delimited Strings for specifying nested properties. If you specify a value to the source property, then you should specify a value to the property property as well. The source property is optional.

The default value is null.

Implementation
public function get source():Object
public function set source(value:Object):void

subFields

property

protected var subFields:Array

Language Version:

ActionScript 3.0

Product Version:

Flex 4.5

Runtime Versions:

Flash Player 10.1, AIR 2.5

An Array of Strings containing the names for the properties contained in the value Object passed to the validate() method. For example, CreditCardValidator sets this property to [ "cardNumber", "cardType" ]. This value means that the value Object passed to the validate() method should contain a cardNumber and a cardType property.

trigger

property

trigger:IEventDispatcher

Language Version:

ActionScript 3.0

Product Version:

Flex 4.5

Runtime Versions:

Flash Player 10.1, AIR 2.5

Specifies the component generating the event that triggers the validator. If omitted, by default Flex uses the value of the source property. When the trigger dispatches a triggerEvent, validation executes.

Implementation
public function get trigger():IEventDispatcher
public function set trigger(value:IEventDispatcher):void

triggerEvent

property

triggerEvent:String

Language Version:

ActionScript 3.0

Product Version:

Flex 4.5

Runtime Versions:

Flash Player 10.1, AIR 2.5

Specifies the event that triggers the validation. If omitted, Flex uses the valueCommit event. Flex dispatches the valueCommit event when a user completes data entry into a control. Usually this is when the user removes focus from the component, or when a property value is changed programmatically. If you want a validator to ignore all events, set triggerEvent to the empty string ("").

Implementation
public function get triggerEvent():String
public function set triggerEvent(value:String):void

Method Detail

addListenerHandler

()

method

protected function addListenerHandler():void

Language Version:

ActionScript 3.0

Product Version:

Flex 4.5

Runtime Versions:

Flash Player 10.1, AIR 2.5

Sets up all of the listeners for the valid and invalid events dispatched from the validator. Subclasses of the GlobalizationValidatorBase class should first call the removeListenerHandler() method, and then the addListenerHandler() method if the value of one of their listeners or sources changes. The CreditCardValidator and DateValidator classes use this function internally.

doValidation

()

method

protected function doValidation(value:Object):Array

Language Version:

ActionScript 3.0

Product Version:

Flex 4.5

Runtime Versions:

Flash Player 10.1, AIR 2.5

Executes the validation logic of this validator, including validating that a missing or empty value causes a validation error as defined by the value of the required property.

If you create a subclass of a validator class, you must override this method.

Parameters

value:Object — Value to validate.

Returns

Array — For an invalid result, an Array of ValidationResult objects, with one ValidationResult object for each field examined by the validator that failed validation.

getValueFromSource

()

method

protected function getValueFromSource():Object

Language Version:

ActionScript 3.0

Product Version:

Flex 4.5

Runtime Versions:

Flash Player 10.1, AIR 2.5

Returns the Object to validate.

Returns

Object — The Object to validate.

handleResults

()

method

protected function handleResults(errorResults:Array):ValidationResultEvent

Language Version:

ActionScript 3.0

Product Version:

Flex 4.5

Runtime Versions:

Flash Player 10.1, AIR 2.5

Returns a ValidationResultEvent from the Array of error results. Internally, this function takes the results from the doValidation() method and puts it into a ValidationResultEvent object. You never call this function directly, and you should rarely override it.

Parameters

errorResults:Array — Array of ValidationResult objects.

Returns

ValidationResultEvent — The ValidationResultEvent returned by the validate() method.

isRealValue

()

method

protected function isRealValue(value:Object):Boolean

Language Version:

ActionScript 3.0

Product Version:

Flex 4.5

Runtime Versions:

Flash Player 10.1, AIR 2.5

Returns true if value is not null.

Parameters

value:Object — The value to test.

Returns

Boolean — true if value is not null.

removeListenerHandler

()

method

protected function removeListenerHandler():void

Language Version:

ActionScript 3.0

Product Version:

Flex 4.5

Runtime Versions:

Flash Player 10.1, AIR 2.5

Disconnects all of the listeners for the valid and invalid events dispatched from the validator. Subclasses should first call the removeListenerHandler() method and then the addListenerHandler method if the value of one of their listeners or sources changes. The CreditCardValidator and DateValidator classes use this function internally.

resourcesChanged

()

method

protected function resourcesChanged():void

Language Version:

ActionScript 3.0

Product Version:

Flex 4.5

Runtime Versions:

Flash Player 10.1, AIR 2.5

This method is called when a GlobalizationValidatorBase is constructed, and again whenever the ResourceManager dispatches a "change" Event to indicate that the localized resources have changed in some way.

This event will be dispatched when you set the ResourceManager's localeChain property, when a resource module has finished loading, and when you call the ResourceManager's update() method.

Subclasses should override this method and, after calling super.resourcesChanged(), do whatever is appropriate in response to having new resource values.

validate

()

method

public function validate(value:Object = null, suppressEvents:Boolean = false):ValidationResultEvent

Language Version:

ActionScript 3.0

Product Version:

Flex 4.5

Runtime Versions:

Flash Player 10.1, AIR 2.5

Performs validation and optionally notifies the listeners of the result.

Parameters

	`value:Object` (default = `null`) — Optional value to validate. If null, then the validator uses the `source` and `property` properties to determine the value. If you specify this argument, you should also set the `listener` property to specify the target component for any validation error messages.

	`suppressEvents:Boolean` (default = `false`) — If `false`, then after validation, the validator will notify the listener of the result.

Returns

ValidationResultEvent — A ValidationResultEvent object containing the results of the validation. For a successful validation, the ValidationResultEvent.results Array property is empty. For a validation failure, the ValidationResultEvent.results Array property contains one ValidationResult object for each field checked by the validator, both for fields that failed the validation and for fields that passed. Examine the ValidationResult.isError property to determine if the field passed or failed the validation.

validateAll

()

method

public static function validateAll(validators:Array):Array

Language Version:

ActionScript 3.0

Product Version:

Flex 4.5

Runtime Versions:

Flash Player 10.1, AIR 2.5

Invokes all the validators in the validators Array. Returns an Array containing one ValidationResultEvent object for each validator that failed. Returns an empty Array if all validators succeed.

Parameters

validators:Array — An Array containing the GlobalizationValidatorBase objects to execute.

Returns

Array — Array of ValidationResultEvent objects, where the Array contains one ValidationResultEvent object for each validator that failed. The Array is empty if all validators succeed.

Event Detail

invalid

Dispatched when validation fails.

The ValidationResultEvent.INVALID constant defines the value of the type property of the event object for an invalid event. The value of this constant is "invalid".

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`.
`field`	The name of the field that failed validation.
`message`	A single string that contains every error message from all of the ValidationResult objects in the results Array.
`results`	An array of ValidationResult objects, one per validated field.
