Class Length

java.lang.Object
  velosurf.validation.FieldConstraint
      velosurf.validation.Length

public class Length
extends FieldConstraint

A string length constraint. Syntax is:

    <column min-len="min" max-len="max"/>
  

where you donnot need to specify both min-len and max-len.

Or:

   <column>
     <min-len value="min-value" [message="error-message"]>
     <max-len value="max-value" [message="error-message"]>
   </column>
 

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.
