of the source object that contains
the value to validate. | Validator | |
| prototype : Object [static]
A reference to the prototype object of a class or function object. | Object | |
| required : Boolean = true
If true, specifies that a missing or empty
value causes a validation error. | Validator | |

Public Methods
| Method | Defined By | ||
|---|---|---|---|
Constructor. | PhoneNumberValidator | ||
| addEventListener(type:String, listener:Function, useCapture:Boolean = false, priority:int = 0, useWeakReference:Boolean = false):void
Registers an event listener object with an EventDispatcher object so that the listener
receives notification of an event. | EventDispatcher | |
|
Dispatches an event into the event flow. | EventDispatcher | |
|
Checks whether the EventDispatcher object has any listeners registered for a specific type
of event. | EventDispatcher | |
|
Indicates whether an object has a specified property defined. | Object | |
|
Called automatically by the MXML compiler when the Validator
is created using an MXML tag. | Validator | |
|
Indicates whether an instance of the Object class is in the prototype chain of the object specified
as the parameter. | Object | |
|
Indicates whether the specified property exists and is enumerable. | Object | |
|
Removes a listener from the EventDispatcher object. | EventDispatcher | |
|
Sets the availability of a dynamic property for loop operations. | Object | |
|
Returns the string representation of this object, formatted according to locale-specific conventions. | Object | |
|
Returns the string representation of the specified object. | Object | |
|
Performs validation and optionally notifies
the listeners of the result. | Validator | |
| [static]
Invokes all the validators in the validators Array. | Validator | |
[static]
Convenience method for calling a validator
from within a custom validation function. | PhoneNumberValidator | ||
|
Returns the primitive value of the specified object. | Object | |
|
Checks whether an event listener is registered with this EventDispatcher object or any of
its ancestors for the specified event type. | EventDispatcher | |
Protected Methods
| Method | Defined By | ||
|---|---|---|---|
|
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 a phone number. | PhoneNumberValidator | ||
|
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 | |

Method Detail
doValidation | () | method |
override protected function doValidation(value:Object):Array| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
Override of the base class doValidation() method
to validate a phone number.
You do not typically 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.
Parameters
value:Object — Object to validate.
|
Array — An Array of ValidationResult objects, with one ValidationResult
object for each field examined by the validator.
|
validatePhoneNumber | () | method |
public static function validatePhoneNumber(validator:PhoneNumberValidator, value:Object, baseField:String):Array| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | 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.
Parameters
validator:PhoneNumberValidator — The PhoneNumberValidator 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.phone,
the baseField value is "phone".
|
Array — An Array of ValidationResult objects, with one ValidationResult
object for each field examined by the validator.
