InheritanceStyleValidator Inheritance Validator Inheritance EventDispatcher Inheritance 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...

()method
override protected function doValidation(value:Object):Array

Language Version: ActionScript 3.0
Product Version: LiveCycle Data Services 3
Runtime Versions: Flash Player 9, AIR 1.1
