In object-oriented programming, the iterator pattern is a design pattern in which an iterator is used to traverse a container and access the container's elements. The iterator pattern decouples algorithms from containers; in some cases, algorithms are necessarily container-specific and thus cannot be...

第17章 迭代器模式(Iterator Pattern) 概述 在面向对象的软件设计中,我们经常会遇到一类集合对象,这类集合对象的内部结构可能有着各种各样的实现,但是归结起来,无非有两点是需要我们去关心的:一是集合内部的数据存储结构,二是遍历集合内部的数据。面向对象设计原则中有一条是类的单一职责原则,所以我们要尽可能的去...
迭代器模式,属于对象行为型模式。它的目的是将一个集合对象的迭代与其本身分离,使这个聚合对象更单纯,并且在遍历的同时不需要暴露该聚合对象的内部结构。 在《设计模式 - 可复用的面向对象软件》一书中将之描述为“ 提供一种方法顺序访问一个聚合对象中各个元素,而又不需暴露对象的内部表示 ”。
Iterator design pattern Take traversal-of-a-collection functionality out of the collection and promote it to "full object status". This simplifies the collection, allows many traversals to be active simultaneously, and decouples collection algorithms from collection data structures. ...

the collection, in a sequential manner. Behavioral design patterns are those that manage object collaboration and the delegation of responsibilities among objects.One of the advantages of the iterator pattern is that it allows you to modify the collection implementation without having to change the ...
