mixin被认为是设计模式吗？ [英] Is mixin considered a design pattern?

问题描述

混合是否被认为是设计模式？结构？

解决方案

他们是一种语言功能。 模式与特征不同，它解决了一系列可能以矛盾的方式影响情境的力量。通过存在或不存在的特征往往会使模式解决的力量创建。许多设计模式（Double Dispatch是一个很好的例子）来解决语言限制（在这种情况下，在单个参数中调度方法）。

Are mixins considered a design pattern? Structural?

解决方案

They're a language feature. A "pattern" is different from a feature, in that it resolves a set of forces that may influence a situation in contradictory ways. Features, by their presence or absence, tend to create the forces that patterns resolve. Many design patterns (Double Dispatch is a good example) came about to work around language limitations (in this case method dispatching on a single argument).
