public class RegexValidator extends java.lang.Object
Regular Expression validation (using JDK 1.4+ regex support).
Construct the validator either for a single regular expression or a set (array) of regular expressions. By default validation is case sensitive but constructors are provided to allow case in-sensitive validation. For example to create a validator which does case in-sensitive validation for a set of regular expressions:
String[] regexs = new String[] {...};
RegexValidator validator = new RegexValidator(regexs, false);
true or false:boolean valid = validator.isValid(value);String result = validator.validate(value);String[] result = validator.match(value);Cached instances pre-compile and re-use java.util.regex.Pattern(s) - which according to the java.util.regex.Pattern API are safe to use in a multi-threaded environment.
