ABSTRACT:
FIELD OF THE INVENTION
The present invention is directed to computer software programs. More particularly, the present invention is directed to an interface between an object-oriented software program and a non-object-oriented software program.
BACKGROUND OF THE INVENTION
Object-oriented programming has become an increasingly popular model for writing computer software. An “object” contains both code (sequences of instructions) and data (information which the instructions operate on). The use of objects can improve the maintenance, reusability, and modifiability of software. Examples of object-oriented programming languages include C++, Smalltalk, and Java.
However, many older software programs are written in non-object-oriented languages. These programs can be referred to as “legacy” programs, and can be written in languages such as Fortran, Basic, and C. Many of these legacy programs include data structures and code structures that need to be used with newer object-oriented languages. Recreating these data structures so that they are compatible with an object-oriented language is time consuming and expensive. Therefore, it is desirable to have a way to interface these legacy data structures with newer object-oriented code.
Based on the foregoing, there is a need for a method and system for interfacing legacy software applications with object-oriented software applications.
SUMMARY OF THE INVENTION
One embodiment of the present invention is a method of wrapping legacy data structures so that an object-oriented program can manipulate their field as if they were properties. In one embodiment, an interface class is defined for each pseudo property to be manipulated. A C++ wrapper is built around each legacy data structure that implements the interface that was defined in the abstract pseudo property class.
