Management of persistent objects in the Nexus distributed system

The Nexus distributed operating system is designed to provide support for persistent objects in a local area network independent of any specific high-level language. The paper describes the generic object management facility of Nexus which can be used to implement different object-oriented programming languages or application systems above Nexus. An object manager serves two functions: first it acts as the class-object, and second it acts as the manager for the instances of its class. The generic object manager is linked to a user-specified type definition to build an object manager for that type. If needed, system developers can tailor the object manager to implement specific policies.<
