接口隔离原理 - 编程到接口 [英] Interface Segregation Principle- Program to an interface

问题描述

我正在阅读有关SOLID和其他设计原则。我认为ISP与程序到接口而不是实现相同。但是看起来这些是不同的原则？

有没有区别？

解决方案>

ISP主要关注每个接口代表一个离散和内聚行为的想法。

也就是说，对象应该做的每一个逻辑组的事情都将映射到一个单一的特定界面。类可能需要做几件事情，但每一件事情都会映射到表示该行为的特定接口。这个想法是每个界面都非常关注。

I was reading about SOLID and other design principles. I thought ISP was the same as "Program to an interface, not an implementation". But it looks like these are different principles?

Is there a difference?

解决方案

ISP is focused on the idea of each interface representing one discrete and cohesive behavior.

That is, each logical group of things an object should do would map to a single specific interface. A class might want to do several things, but each thing would map to a specific interface representing that behavior. The idea is each interface is very focused.
