The TopLink optimistic locking policies that "Working with Optimistic Locking" describes implement the OptimisticLockingPolicy interface, referenced throughout the TopLink code. You can create more policies by implementing this interface and implementing the methods defined.
Use the Locking tab (see Figure 4-16) to specify locking policies for the TopLink Mapping editor, or refer to the book OracleAS TopLink Application Developer's Guide for more information.
