com.adobe.fiber.styles.StyleValidator - ActionScript® 3.0 Reference for the Adobe® Flash® Platform

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

Language Version:

ActionScript 3.0

Product Version:

Adobe Digital Enterprise Platform Data Services for Java EE 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, and so forth.
