Examples of javax.jdo.PersistenceManager.makeTransactional()

javax.jdo.PersistenceManager.makeTransactional()

Make an instance subject to transactional boundaries.

Transient instances normally do not observe transaction boundaries. This method makes transient instances sensitive to transaction completion. If an instance is modified in a transaction, and the transaction rolls back, the state of the instance is restored to the state before the first change in the transaction.

For persistent instances read in optimistic transactions, this method allows the application to make the state of the instance part of the transactional state. At transaction commit, the state of the instance in the cache is compared to the state of the instance in the data store. If they are not the same, then an exception is thrown. @param pc the instance to make transactional.

  assertNull("Object ID should be null", 
       JDOHelper.getObjectId(pc));
  assertNotNull("PersistenceManager should not be null",
       JDOHelper.getPersistenceManager(pc));
