4.7 Summary

This chapter completes the introduction of UML-F tags. It has introduced the five framework construction principles: Unification, Separation and those with a recursive flavor that have the same name as in the GoF catalog: Composite, Decorator, and Chain of Responsibility. We have presented the UML-F tags for the Unification, Separation and Composite construction principles. In addition, we chose the Factory Method and Strategy patterns from the GoF catalog and a domain-specific pattern called Calculation to illustrate the UML-F tag introduction mechanism. Instead of listing the UML-F tags for each of the construction principles and patterns, the chapter explains and exemplifies how to derive the UML-F tags in a straightforward manner from their static structure. Thus, understanding the tag definition mechanism is a key goal of this chapter. Appendix B complements it and introduces the UML-F tags for the other GoF framework patterns.
