Sharing data structures between processes by semi-invasive hybrid approach

Abstract

Techniques herein are for sharing data structures between processes. A method involves obtaining a current memory segment that begins at a current base address within a current address space. The current memory segment comprises a directed object graph and a base pointer. The graph comprises object pointers and objects. For each particular object, determine whether a different memory segment contains an equivalent object that is equivalent to the particular object. If the equivalent object exists, for each object pointer having the particular object as its target object, replace the memory address of the object pointer with a memory address of the equivalent object that does not reside in the current memory segment. Otherwise, for each object pointer having the particular object as its target object, increment the memory address of the object pointer by an amount that is a difference between the current base address and the original base address.
