Abstract

A system, method and article of manufacture for automatically inserting concurrency object services into binary classes in an information handling system employing object oriented technology, includes the steps of recognizing a constraint indicating that an object does not support concurrency and generating a concurrent version of the object. One alternative for generating a version of an object supporting concurrency is automatic transactional locking. The approach includes the steps of inheriting from the Lockable class which adds state to a class to allow object-level locking, inheriting from the Serialised metaclass which adds before and after methods to all methods of the non-concurrent version, and the object must be a RecoverableObject. Another alternative for generating a version of an object supporting concurrency is automatic per method locking. The approach includes the steps of inheriting from the Lockable class which adds state to a class, and inheriting from the Serialised metaclass which adds before and after methods to all methods of the non-concurrent version. Another alternative for generating a version of an object supporting concurrency is explicit locking. The approach for RecoverableObjects includes the step of inheriting from a ConcurrentObject (which is derived from the Lockable class). The approach for non-RecoverableObjects also includes the step of inheriting from a ConcurrentObject.
