**Intent:** Provide a way to access the elements of an aggregate object
|
|
sequentially without exposing its underlying representation.
|
|
|
|
|
|
|
|
**Applicability:** Use the Iterator pattern
|
|
|
|
* 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
|
|
|
|
**Real world examples:**
|
|
|
|
* [java.util.Iterator](http://docs.oracle.com/javase/8/docs/api/java/util/Iterator.html) |
