The Mediator design pattern is one of the twenty-three well-known design patterns that describe how to solve recurring design problems to design flexible and reusable object-oriented software, that is, objects that are easier to implement, change, test, and reuse.. What problems can the Mediator design pattern solve? The mediator pattern falls under the behavioral pattern category. It's difficult to answer this question. Purpose¶. Intent¶. Automatically and dynamically allocated objects are initialized only if an initial value is explicitly specified; otherwise they initially have indeterminate values (typically, whatever,Another issue is that heap memory allocation has to be synchronized with its actual usage in any program in order for it to be reused as much as possible. According to the Gang of Four, the Mediator is a way to “define an object that encapsulates how a set of objects interact. Mediator promotes loose coupling by keeping objects from referring to each other explicitly, and it lets you vary their interaction independently” (Design Patterns: Elements of Reusable Object-Oriented Software, 2013, p. 273). Mediator pattern is used to reduce communication complexity between multiple objects or classes. 二十四种设计模式：中介者模式(Mediator Pattern) 中介者模式(Mediator Pattern) 介绍用一个中介对象来封装一系列的对象交互.中介者使各对象不需要显式地相互引用,从而使其耦合松散,而且可以独立地改变它们之间的交互. This interaction can be direct (point-to-point) as long as the number of objects referring to each other directly is very low. 3.4.1.
