门面设计模式 [英] Facade Design Pattern

问题描述

系统应该只有一个外观设计模式？

解决方案

没有。没有这样的限制，没有一个原因。为什么？

一个明显的情况是系统中包含一些子系统及其各自的外观，但即使是相同的系统也可以有多个外观，为什么不呢？

A system should have one and only one facade design pattern?

解决方案

No. There is no such limitation, there is no a single reason for that. Why?
One obvious situation is when a system contains some subsystems in it, with their respective facades, but even the same very system can have more then one facade, why not?
