Automated Application of Design Patterns to Legacy Code

Research output: Contribution to conference (non-published works)Paperpeer-review


In reengineering legacy code it is frequently useful to introduce a design pattern in order to add clarity to the system and thus facilitate further program evolution. We show that this type of transformation can be automated in a pragmatic manner and propose a methodology for the development of design pattern transformations. We address the issues of the definition of a starting point for the transformation, the decomposition of a pattern into minipatterns and the development of corresponding minitransformations that can introduce these minipatterns to a program. The architecture of an existing software prototype is also discussed and the results of applying this methodology to develop a transformation for the Factory Method pattern are presented.
