com.adobe.fiber.styles.StyleValidator - Adobe® Flex® 4 Language Reference (Flex 4)

Package	com.adobe.fiber.styles
Class	public class StyleValidator
Inheritance	StyleValidator Validator EventDispatcher Object

Language Version:

ActionScript 3.0

Product Version:

LiveCycle Data Services 3

Runtime Versions:

Flash Player 9, AIR 1.1

A wrapper around mx.validators.Validator that enables runtime customization of the function used for validation, doValidation. The wrapper also sets the required flag on the wrapped validator to false as generated value objects perform required validation outside of the validators. Validators are used by styles to calculate validation expressions and for exposing built-in validators such as social security number, credit card number, email, etc...

		toLocaleString():String Returns the string representation of this object, formatted according to locale-specific conventions.	Object
		toString():String Returns the string representation of the specified object.	Object
		validate(value:Object = null, suppressEvents:Boolean = false):ValidationResultEvent Performs validation and optionally notifies the listeners of the result.	Validator
		validateAll(validators:Array):Array [static] Invokes all the validators in the validators Array.	Validator
