velosurf.validation
Class Range

java.lang.Object
  velosurf.validation.FieldConstraint
      velosurf.validation.Range

public class Range
extends FieldConstraint

A type and range constraint on numbers. Syntax is:

    <column [type="integer"] [min="min"] [max="max"]/>
  

where you donnot need to specify both min and max.

Or:

     <integer|number [min="min-value"] [max="max-value"] [message="error-message"] />
 

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