public class Regex
extends FieldConstraint

A regular expression pattern constraint. Syntax is:

    <column regex="regex-pattern"/>
  

Or:

     <column>
       <regex pattern="regex-pattern" [message="error-message"] >
     </column>
   

Note: this constraint is not meant to replace an internal SQL constraint clause in the database, since it cannot be made sure that complex updates will respect this constraint.
