What is Iterator pattern?
- A design pattern that allows the client to traverse a collection of objects, without exposing the underlying representation of the collection
- A design pattern that converts a request into a standalone object, allowing the client to parametrize objects with different requests, queue a request, or log requests
- A design pattern that provides a simplified interface to a complex system, allowing the client to interact with the system through a single, unified interface
- A design pattern that uses shared objects to support large numbers of similar objects efficiently
Iterator pattern is a design pattern that allows the client to traverse a collection of objects, without exposing the underlying representation of the collection. The pattern involves creating an iterator class that implements the iterator interface, and provides a way for the client to access the elements of the collection one at a time, in a standardized manner. This pattern can be useful in situations where you want to provide a standard way for the client to access the elements of a collection, without exposing the internal representation of the collection.
