In object-oriented programming, the command pattern is a behavioral design pattern in which an object is used to encapsulate all information needed to perform an action or trigger an event at a later time. This

命令模式(Command Design Pattern) 命令模式将请求(命令)封装为一个对象,这样可以使用不同的请求参数化其他对象(将不同请求依赖注入到其他对象),并且能够支持请求(命令)的排队执行、记录日志、撤销等(附加控制)功能 命令模式的原理与实现 落实到编码实现,命令模式用的最核心的实现手段,是将函数封装成对象。我们知道,C...

Parts of the command design pattern The command pattern is divided into five parts: TheCommanddeclares an interface for the execution of an operation. TheConcreteCommanddefines a binding between aReceiverand an action. TheClientcreates a ConcreteCommand object and sets aReceiverfor the command. ...

设计模式(18)-Command Pattern 一、 命令(Command)模式 命令(Command)模式属于对象的行为模式【GOF95】。命令模式又称为行动(Action)模式或交易(Transaction)模式。命令模式把一个请求或者操作封装到一个对象中。命令模式允许系统使用不同的请求把客户端参数化,对请求排队或者记录请求日志,可以提供命令的撤销和恢复功能...
