getStateLock

java.util.concurrent.locks.ReentrantLock getStateLock()

Each time CDORevision or CDOState of an CDOObject is modified, ensure that no concurrent access is modifying it at the same time. Uses getStateLock() to be thread safe.

In the case where CDOObject.cdoRevision() or CDOObject.cdoState() is called without using this lock, it is not guarantee that the state didn't change immediately after.

if (cdoObject.cdoState() != CDOState.PROXY) { // At this point could be a proxy! cdoObject.cdoRevision(); }

The reason were we didn't use CDOView.getLock() is to not allow the access of that lock to the users since it is very critical. Instead of giving this API to the end-users, a better API should be given in the CDOObject to give them want they need.
