Towards A Catalog of Design Patterns Variants
Ghulam Rasool, Hassan Akhtar · 2019
With increasing applications of design patterns for the development of quality software applications, the accurate recovery of patterns from software applications remained active research area in the last one and half decade. The implementation variations for standard patterns hamper the accuracy of existing pattern recovery techniques and tools. There is no standard catalog on all variants of Gang of Four(GoF) design patterns in the literature. We present the first catalog on variations of GoF design patterns that are discussed in different publications, blogs and discussion forums at different levels of abstraction. A catalog with 107 variants of standard patterns might serve as a knowledge base for the design pattern research community and it might be helpful to specify GoF patterns and their variants. The critical analysis and observations on GoF design patterns and their variants are presented based on the whole study and our experience.
