Abstract
A new method for implementing hierarchical object oriented designs of hard real time systems in Ada 95 is described in the paper. The approach is based on the HRT-HOOD method, but it can be extended to other OOD methods as well. Ada child packages are used to implement object aggregation or inclusion hierarchies. Renaming in the body, a new Ada 95 feature, is used to provide efficient mapping of composite object operations to component operations. An example is given in order to illustrate the method.
HOOD is a trade mark of the HOOD User Group.
