Applying object oriented programming to developing programs on CTRON interfaces

One of the objectives of the CTRON interface specifications is to promote software-reutilization for real-time applications by standardizing operating system interfaces. Although this approach does improve reusability by improving portability, means for gaining better composability has to be taken into consideration to achieve more advanced reutilization. Object oriented programming (OOP) which supports encapsulation, polymorphism and inheritance is an appropriate programming paradigm for improving composability of software-modules. The authors describe how they apply OOP to systems based on the CTRON specifications and describe the C++ class libraries they have been designing. They describe how they evaluate the performance, reusability and portability of programs that use the base class libraries
