  • System for combining a global object identifier with a local object address in a single object pointer
    Patent number: 5581765
    Abstract: An object pointer data structure for efficiently combining an object identifier and an object address for use in object-oriented programming systems. An object address is a value that allows a client application or process to conduct high-performance operations on an object in the client's local virtual address space. An object identifier is a value that can be used to uniquely identify an object for the lifetime of that object across some defined domain, such as an entire universe of computer systems. The data structure of this invention defines an object pointer that is larger than the object address but smaller than the combination of the object identifier and object address. The truncated object pointer structure preserves all information from both object address and object identifier by forcing a portion of the local object address in each address space to be equal to a portion of the invariant object identifier.
