  nl.gx.webmanager.handler.forms.validation.ElfCheckFormPartValidator

All Implemented Interfaces:

FormComponent, Validator

public class ElfCheckFormPartValidator
extends java.lang.Object
implements Validator

Performs an 'elfproef' ('eleven check') on the formpart to check if it could be a valid Dutch bank account number. This check also prevents acceptance of bank account numbers where two digits are switched, which is a common typing mistake. Note: For Dutch postal bank account (Postbank) numbers there is no check. All numbers below 100.000.000 could be postal bank account numbers.

Variable	Type	Mode	Default	Description
wmformpart	Parameter	Required	-	The formpart to validate (a bank account number).
invalid	Message	-	-	If the formpart value did not pass the 'Elfproef'.

Example usage:

• Check if number could be a Dutch bank account number.
