Method and system for maintaining consistency of shared objects based upon instance variable locking

摘要

The invention comprises a method and system for maintaining the integrity of shared objects based upon instance variable locking. In accordance with the method of the invention, a locking tag is attached to an instance variable, indicating that the instance variable was read by a first process. Reads of the instance variable by a second process are allowed while the first locking tag is present. A second locking tag is attached to the instance variable, indicating that the instance variable was read by the second process.
