它描述了在面向对象软件设计过程中针对特定问题的简洁而优雅的解决方案。设计模式捕获了随时间进化与发展的问题的求解方法，因此它们并不是人们从一开始就采用的设计方案。它们反映了不为人知的重新设计和重新编码的成果，而这些都来自软件开发者为了设计出灵活可复用的软件而长时间进行的艰苦努力。设计模式捕获了这些解决方案，并用简洁易用的方式表达出来。-It describes the object-oriented software design process-specific issues concise and elegant solution. Design patterns capture the evolution over time with the development of the solution, so they are not people from the very beginning the design. They reflected the arcana of the re-design and re-encode the results, which came from software developers to design flexible and reusable software for a long time of hard work. Design patterns capture these solutions, and with simple and user-friendly way out.
