ABSTRACT:
A mechanism is provided that transforms a class hierarchy of an object-oriented program to a new class hierarchy based upon a set of rules. The new class hierarchy is constructed by transforming a class hierarchy based upon a set of transformation rules which perform one of the following operations: i) merging of two classes; ii) removing a virtual inheritance relation; and iii) replacing a virtual inheritance relation with a non-virtual inheritance relation. The transformation is preferably generated on either a specialized class hierarchy or a class hierarchy obtained by class hierarchy slicing. Thus, the new class hierarchy is a simplification of the inheritance structure, which may result in a reduction in the number of compiler-generated fields in objects, and hence in a reduction of object size of the program.
