Class ConcurrentUpdateDetector

java.lang.Object
  atg.commerce.util.ConcurrentUpdateDetector

public class ConcurrentUpdateDetector
extends java.lang.Object

This class is intended to detect concurrent update attemps by checking exceptions to see if they are, or contain, ConcurrentUpdateExceptions (CUE) or InvalidVersionExceptions (IVE). A form handler can use this class to determine whether the user can be prompted to resubmit the form.

Concurrent updates can happen when users are using more than one browser to update the same user data. The Repository and Order object structure check for concurrent update attempts to ensure the data integrity of the order data. If a concurrent update attempt is detected, the Repository or OrderManager will throw an exception to indicate this condition. This class can be used to catch this condition and alert the user that they should resubmit their changes for them to take effect.
