Traversing Complex Collections

Explore how the Iterator design pattern enables you to handle complex collections without exposing their internal algorithms or structures. Learn to create simplified, sequential access for clients, ensuring your data structures remain flexible and maintainable.

Problem statement

Let’s suppose that we have a really complex data structure due to various constraints that we have to overcome. Perhaps, we need to arrange the data into a binary search tree to enable an efficient search algorithm. Or perhaps it’s a linked list where each item in the collection needs to know about the next item.

In any ...
