Incremental Language Conversion Method to Convert C++ into Ada95

摘要

This thesis develops a methodology to incrementally convert a legacy objectoriented C++ application into Ada95. Using the experience of converting a graphic application, called Remote Debriefing Tool (RDT), in the Graphics Lab of the Air Force Institute of Technology (AFIT), this effort defined a process to convert a C++ application into Ada95. The methodology consists of five phases: (1) reorganizing the software application, (2) breaking mutual dependencies, (3) creating package specifications to interface the existing C++ classes, (4) converting C++ code into Ada programs, and (5) embellishing. This methodology used the GNAT's C++ low level interface capabilities to support the incremental conversion. The goal of this methodology is not only to correctly convert C++ code into Ada95, but also to take advantage of Ada's features which support good software engineering principles.
