Annex B: Design Patterns
The design patterns used in CBR*Tools are introduced in the memorandum below. The objective thus is not to describe each pattern used in an exhaustive way, but only to facilitate the reading of the document by pointing out the fundamental characteristics of these patterns. One will be able to refer to works specialiced for more complete descriptions (Gamma et al, 1995; Pree, 1994; Bushmann et al, 1996). Each pattern is introduced according to a card which comprises six parts:
- name: the name of the pattern in English as it is defined in (Gamma and Al, 1995),
- description: describes very briefly the context, the problem, and the solution approached by this pattern,
- structure and components: list of the typical elements occuring in the pattern with graphical illustrations (class diagram and if necessary object diagram),
- collaborations: defines the principal interactions between the components by, if needed, the graphical representation of a sequence diagram,
- strengths and weaknesses: presents the principal forces (advantages) and weaknesses (disadvantages) of the pattern, either in its implementation, or in its operation,
- use in CBR*Tools: references principal uses of the pattern in CBR*Tools.
The cards are classified in alphabetical order:
