门面模式( Facade Pattern) 也叫做外观模式, 是一种比较常用的封装模式, Provide a unified interface to a set of interfaces in a subsystem.Facade defines a higher-level interface that makes the subsystem easier to use.( 要求一个子系统的外部与其内部的通信必须通过一个统一的对象进行。 门面模式提供一...

This pattern involves one wrapper class which contains a set of methods available for the client. This pattern is particularly used when a system is very complex or difficult to understand and when the system has multiple subsystems. Let’s see the below UML diagram, Image source:Wikipedia Here...

外观模式主要是为了为一组接口提供一个一致的界面。从而使得复杂的子系统与用户端分离解耦。 有点类似家庭常用的一键开关,只要按一个键,台灯卧室客厅的灯都亮了。虽然他们各有各自的开关,但是对外用一个来控制。 应用场景 1 为复杂系统 提供简单的接口。
The biggest assumption in Facade pattern is that objects are often Singletons because only one Facade object is required. Facade defines a new interface Both, Adapter and Facade are both wrappers. But they are different kinds of wrappers. The intent of Facade is to produce a simpler interfac...
