## 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) |
