Sets up all of the listeners for the
valid and invalid
events dispatched from the validator. | Validator | |
[override]
Override of the base class doValidation() method
to validate an e-mail address. | EmailValidator | ||
|
Returns the Object to validate. | Validator | |
|
Returns a ValidationResultEvent from the Array of error results. | Validator | |
|
Returns true if value is not null. | Validator | |
|
Disconnects all of the listeners for the
valid and invalid
events dispatched from the validator. | Validator | |

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

Descrizione dei metodi
doValidation | () | metodo |
override protected function doValidation(value:Object):Array| Versione linguaggio: | ActionScript 3.0 |
| Versione prodotto: | Flex 3 |
| Versioni runtime: | Flash Player 9, AIR 1.1 |
Override of the base class doValidation() method
to validate an e-mail address.
You do not call this method directly; Flex calls it as part of performing a validation. If you create a custom Validator class, you must implement this method.
Parametri
value:Object — Either a String or an Object to validate.
|
Array — An Array of ValidationResult objects, with one ValidationResult
object for each field examined by the validator.
|
validateEmail | () | metodo |
public static function validateEmail(validator:EmailValidator, value:Object, baseField:String):Array| Versione linguaggio: | ActionScript 3.0 |
| Versione prodotto: | Flex 3 |
| Versioni runtime: | Flash Player 9, AIR 1.1 |
Convenience method for calling a validator from within a custom validation function. Each of the standard Flex validators has a similar convenience method.
Parametri
validator:EmailValidator — The EmailValidator instance.
| |
value:Object — A field to validate.
| |
baseField:String — Text representation of the subfield
specified in the value parameter.
For example, if the value parameter specifies value.email,
the baseField value is "email".
|
Array — An Array of ValidationResult objects, with one
ValidationResult object for each field examined by the validator.
