Method and apparatus for efficient representation of variable lenght identifiers in a distributed object system

摘要

In a CORBA distributed object system, potential object name ambiguities in the Portable Object Adapter are resolved without using variable-length object identifiers by translating the variable length identifiers into a fixed length compact identifier, such as a integer. The mapping for persistent objects is maintained on an ID server with persistent state and the mappings are ultimately written to a file. A server IDL interface is defined to the ID server which interface includes a method that accepts a variable length fully qualified name and returns the compact identifier. The method assigns an identifier if one does not exist. Another method accepts the identifier and returns the name.
