Iterator

Iterator pattern has behavioral purpose and applies to objects. The pattern provides a way to access the elements of an aggregate object sequentially without exposing its underlying representation.

When to use

to access an aggregate object's contents without exposing its internal representation
to support multiple traversals of aggregate objects
to provide a uniform interface for traversing different aggregate structures (to support polymorphic iteration)
