org.grails.validation.routines.RegexValidator

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);

Validate true or false:

boolean valid = validator.isValid(value);

Validate returning an aggregated String of the matched groups:

String result = validator.validate(value);

Validate returning the matched groups:

String[] result = validator.match(value);

Cached instances pre-compile and re-use {@link Pattern}(s) - which according to the {@link Pattern} API are safe to use in a multi-threaded environment. @since Validator 1.4
