AbstractCDOLockState
public interface CDOLockState extends CDOIDAndBranch
A client-side representation of all the locks on a single CDOObject.

As an individual lock is always owned by view, which in turn is owned by a session, the methods on this interface return instances of CDOLockOwner which carry that information.
