Abstract
A method and apparatus for providing selective object locking is provided. First, a lock object is designated. The identity of the lock object is then made available to objects in an object calling hierarchy. The first object invoked by the calling thread obtains a lock on the lock object to protect data associated with the first invoked object. Other objects in the object calling hierarchy can relock the lock object to protect their data. The invention also provides for selective object locking by providing the capability for a calling thread to specify that no object locking is to be preformed, which causes objects invoked by the calling thread to not perform object locking.
