  <mx:SocialSecurityValidator
    allowedFormatChars=" -"
    invalidCharError="You entered invalid characters in your Social Security number."

    zeroStartError="Invalid Social Security number; the number cannot start with 000."

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 Social Security number.

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.

Parameters

value:Object — Object to validate.

Returns

Array — An Array of ValidationResult objects, with one ValidationResult object for each field examined by the validator.

validateSocialSecurity

()

method

public static function validateSocialSecurity(validator:SocialSecurityValidator, 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. Each of the standard Flex validators has a similar convenience method.

Parameters

	`validator:SocialSecurityValidator` — The SocialSecurityValidator 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.social, the `baseField` value is `social`.

Returns

Array — An Array of ValidationResult objects, with one ValidationResult object for each field examined by the validator.
