An Adjunct to Existing Methods ¶
다른 디자인 방법들의 보조.
DesignPatterns are an important piece that's been missing from object-oriented design methods. (primitive techniques, applicability, consequences, implementations ...)
A Target for Refactoring ¶
리펙토링을 위한 목표.
DesignPatterns capture many of the structures that result from refactoring. Using these patterns early in the life of a design prevents later refactorings. But even if you don't see how to apply a pattern until after you've built your system, the pattern can still show you how to change it. Design patterns thus provide targets for your refactorings.
