Taalversie:

ActionScript 3.0

Productversie:

Flex 4.5

Runtimeversies:

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.

Deze eigenschap kan als de bron voor gegevensbinding worden gebruikt. Wanneer deze eigenschap wordt gewijzigd, wordt de gebeurtenis unused verzonden.

Implementatie
protected function get resourceManager():IResourceManager

source

eigenschap

source:Object

Taalversie:

ActionScript 3.0

Productversie:

Flex 4.5

Runtimeversies:

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.

De standaardwaarde is null.

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

subFields

eigenschap

protected var subFields:Array

Taalversie:

ActionScript 3.0

Productversie:

Flex 4.5

Runtimeversies:

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

eigenschap

trigger:IEventDispatcher

Taalversie:

ActionScript 3.0

Productversie:

Flex 4.5

Runtimeversies:

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.

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

triggerEvent

eigenschap

triggerEvent:String

Taalversie:

ActionScript 3.0

Productversie:

Flex 4.5

Runtimeversies:

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 ("").

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

addListenerHandler

()

methode

protected function addListenerHandler():void

Taalversie:

ActionScript 3.0

Productversie:

Flex 4.5

Runtimeversies:

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

()

methode

protected function doValidation(value:Object):Array

Taalversie:

ActionScript 3.0

Productversie:

Flex 4.5

Runtimeversies:

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.

Geretourneerde waarde

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

()

methode

protected function getValueFromSource():Object

Taalversie:

ActionScript 3.0

Productversie:

protected function handleResults(errorResults:Array):ValidationResultEvent

Taalversie:

ActionScript 3.0

Productversie:

Flex 4.5

Runtimeversies:

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.

Geretourneerde waarde

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

isRealValue

()

methode

protected function isRealValue(value:Object):Boolean

Taalversie:

ActionScript 3.0

Productversie:

Flex 4.5

Runtimeversies:

Flash Player 10.1, AIR 2.5

Returns true if value is not null.

Parameters

value:Object — The value to test.

Geretourneerde waarde

Boolean — true if value is not null.

removeListenerHandler

()

methode

protected function removeListenerHandler():void

Taalversie:

ActionScript 3.0

Productversie:

Flex 4.5

Runtimeversies:

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

()

methode

protected function resourcesChanged():void

Taalversie:

ActionScript 3.0

Productversie:

Flex 4.5

Runtimeversies:

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

()

methode

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

Taalversie:

ActionScript 3.0

Productversie:

Flex 4.5

Runtimeversies:

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.

Geretourneerde waarde

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.

methode

public static function validateAll(validators:Array):Array

Taalversie:

ActionScript 3.0

Productversie:

Flex 4.5

Runtimeversies:

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.

Geretourneerde waarde

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.
