What are iterator patterns in software design?
Iterator patterns are design patterns that provide a way to access elements of a collection sequentially without exposing its underlying representation.
Can you give me an example of how to implement an iterator pattern?
Sure! In Python, you can create an iterator by defining a class with __iter__()
and __next__()
methods.
What are the benefits of using iterator patterns?
Iterator patterns promote loose coupling, allow for easy traversal of complex data structures, and enhance code readability.
Are there any drawbacks to using iterator patterns?
One drawback is that they can introduce additional complexity, especially if the collection is large or requires multiple iterators.
