Examples of org.prevayler.Prevayler

org.prevayler.Prevayler
Implementations of this interface can provide transparent persistence and replication to all Business Objects in a Prevalent System. ALL operations that alter the observable state of the Prevalent System must be implemented as Transaction or TransactionWithQuery objects and must be executed using the Prevayler.execute(...) methods. See the demo applications in org.prevayler.demos for examples. @param < P> The type of object you intend to persist as a Prevalent System.
@see org.prevayler.PrevaylerFactory
