Class OneOf

  velosurf.validation.FieldConstraint
      velosurf.validation.OneOf

public class OneOf
extends FieldConstraint

An enumeration constraint. Syntax is:

    <column one-of="value1,value2,value3..."/>
  

Or:

     <column>
       <one-of [message="error-message"]>
         <value>value1</value>
         <value>value2</value>
         <value>value3</value>
         ...
       </one-of>
     </column>
   

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