Examples of OptimisticTransactionContext

org.jboss.cache.transaction.OptimisticTransactionContext
Subclasses the {@link PessimisticTransactionContext} class to add a {@link TransactionWorkspace}. Used with optimistic locking where each call is assigned a trasnaction and a transaction workspace. @author Manik Surtani (manik AT jboss DOT org) @author Steve Woodcock (stevew@jofti.com) @deprecated will be removed along with optimistic and pessimistic locking.
