Examples of com.sun.sgs.test.util.DummyTransaction

com.sun.sgs.test.util.DummyTransaction
Provides a simple implementation of Transaction, for testing. If using this class with DummyTransactionProxy, make sure to call DummyTransactionProxy.setCurrentTransaction with the DummyTransaction, so that the proxy's transaction is cleared when the transaction is terminated.
