Abstract
The preferred embodiment of the present invention facilitates the creation, storage and interaction of persistent objects using single level storage semantics on commodity systems. Specifically, the present invention defines several objects used to implement persistent objects in a shared address space. The preferred embodiment includes a Class Encapsulator class and the Object Encapsulator class that are preferably designed to encapsulate the class data and instance data, respectively. In particular, a Class Encapsulator object would preferably be created in a Persistent Container for each class of objects loaded into that Persistent Container. The Class Encapsulator object would include all of the specific data needed to implement its corresponding class. Likewise, an Object Encapsulator object would preferably be created to encapsulate each object to be stored persistently in the shared address space. A Persistent Handle class is preferably defined to store the shared address space address of the Class Encapsulator object and the Object Encapsulator object.
