Method Detail

runTransaction

void runTransaction()
             throws PersistitException,
                    RollbackException

Interface for application logic that is to be run within the scope of a Transaction. The Transaction.run(com.persistit.TransactionRunnable) method accepts a TransactionRunnable and runs it in a transactional context.

The implementation of this method generally should never invoke methods of the enclosing transaction, (which is not supplied). The implementation's application logic may throw a RollbackException if rollback is necessary due to conditions detected by the application itself. Persistit operations such as Exchange.fetch() and Exchange.store(com.persistit.Key, com.persistit.Value) may also throw RollbackExceptions when executed within a transaction; the application logic implementing this method should generally not catch PersistitException, including RollbackException . The the calling code in Transaction is designed to handle them.

Throws:

PersistitException

RollbackException
