public class RegExpValidator
extends Object
implements javax.faces.component.StateHolder, javax.faces.validator.Validator

RegExpValidator is a Validator that checks the value of the corresponding component against specified pattern using Java regular expression syntax. The regular expression syntax accepted by the RegExpValidator class is same as mentioned in class Pattern in package java.util.regex. The following algorithm is implemented:
