RE: PersistenceBroker State Question

[Lance Eason]

It all depends on the cache you use (specified in OJB.properties).  
ObjectCacheDefaultImpl will never get flushed automatically (which can be problematic 
for transactional isolation).  ObjectCachePerBrokerImpl will get flushed on 
broker.close().

Subject: PersistenceBroker State Question


Pertaining to caching and speed of the PersistenceBroker, am I on the right
track for structuring calls like so:

// Method OjbUserDao.insertUser()
public void insertUser(User user) throws Exception
{
        // calls PersistenceBrokerFactory.defaultPersistenceBroker()
        PersistenceBroker broker =
OjbDaoFactory.getInstance().createBroker();
        try
        {
                broker.beginTransaction();
                broker.store(user, ObjectModificationDefaultImpl.INSERT);
                broker.commitTransaction();
        }
        finally
        {
                        broker.close();
        }
}

Does the cache in general get flushed when I call broker.close()? I'm just
using the Broker in Single-VM mode.
