CDA Pattern Classification (Overview)

Sunday, July 20th, 2008

Thinking for a while I realized that it is not possible to create one classification scheme because one pattern can belong to several categories. Therefore I came up with the following draft list of them:

- Space / Mode
- Memory dump type
- Dynamical (Activity) / Structural (State)
- Architecture / Design / Implementation
- Entity-dependence
- System / Subsystem / Component / Object
- Cosmogony (How?)
- Management (Why?)
- Error class
- Observable behaviour

Next two posts will present classification based on Space/Mode and Memory dump type.

DebugWare Patterns (Part 2)

Next pattern is called

Tool Façade (or Tool Facade)

It is used when there is a tool with a cumbersome interface like command line with many options and there is a need for a better and easier to use interface, for example, GUI. This can be illustrated on the following UML component diagram:

Excellent example of this pattern is:

StressPrinters

designed as a GUI wrapper around command line tool AddPrinter. Adding the powerful GUI interface allowed to extend its functionality and even find new domains, like testing, where the tool can be used. Excellent information about this tool can be found in the article:
