| Versione prodotto: | Flex 4.5 |
| Versioni runtime: | 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.
Il valore predefinito è true.

listener:Object| Versione linguaggio: | ActionScript 3.0 |
| Versione prodotto: | Flex 4.5 |
| Versioni runtime: | 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.

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.
Il valore predefinito è null.

| Versioni runtime: | 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.
Questa proprietà può essere utilizzata come origine per l’associazione di dati. Quando questa proprietà viene modificata, invia l’evento unused .

source:Object| Versione linguaggio: | ActionScript 3.0 |
| Versione prodotto: | Flex 4.5 |
| Versioni runtime: | 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.
Il valore predefinito è null.

| Versioni runtime: | 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 | proprietà |
trigger:IEventDispatcher| Versione linguaggio: | ActionScript 3.0 |
| Versione prodotto: | Flex 4.5 |
| Versioni runtime: | 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.

public function get trigger():IEventDispatcher public function set trigger(value:IEventDispatcher):voidtriggerEvent | proprietà |
triggerEvent:String| Versione linguaggio: | ActionScript 3.0 |
| Versione prodotto: | Flex 4.5 |
| Versioni runtime: | 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 ("").

Constructor.
addListenerHandler | () | metodo |
protected function addListenerHandler():void| Versione linguaggio: | ActionScript 3.0 |
| Versione prodotto: | Flex 4.5 |
| Versioni runtime: | 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 | () | metodo |
protected function doValidation(value:Object):Array| Versione linguaggio: | ActionScript 3.0 |
| Versione prodotto: | Flex 4.5 |
| Versioni runtime: | 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.
Parametri
value:Object — Value to validate.
|
Array — For an invalid result, an Array of ValidationResult objects,
with one ValidationResult object for each field examined
by the validator that failed validation.

protected function handleResults(errorResults:Array):ValidationResultEvent| Versione linguaggio: | ActionScript 3.0 |
| Versione prodotto: | Flex 4.5 |
| Versioni runtime: | 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.
Parametri
errorResults:Array — Array of ValidationResult objects.

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

protected function removeListenerHandler():void| Versione linguaggio: | ActionScript 3.0 |
| Versione prodotto: | Flex 4.5 |
| Versioni runtime: | 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 | () | metodo |
protected function resourcesChanged():void| Versione linguaggio: | ActionScript 3.0 |
| Versione prodotto: | Flex 4.5 |
| Versioni runtime: | 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 | () | metodo |
public function validate(value:Object = null, suppressEvents:Boolean = false):ValidationResultEvent| Versione linguaggio: | ActionScript 3.0 |
| Versione prodotto: | Flex 4.5 |
| Versioni runtime: | Flash Player 10.1, AIR 2.5 |
Performs validation and optionally notifies the listeners of the result.
Parametri
value:Object (default = null)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)false, then after validation,
the validator will notify the listener of the result.
|
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.

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.
Parametri
validators:Array — An Array containing the GlobalizationValidatorBase
