Interface OrderedMapIterator<K,V>

Type Parameters:

K - the type of the keys in the map

V - the type of the values in the map

All Superinterfaces:

Iterator<K>, MapIterator<K,V>, OrderedIterator<K>

All Known Implementing Classes:

AbstractLinkedMap.LinkMapIterator, AbstractOrderedMapIteratorDecorator, AbstractSortedMapDecorator.SortedMapIterator, DualTreeBidiMap.BidiOrderedMapIterator, EmptyOrderedMapIterator, UnmodifiableOrderedMapIterator
```
public interface OrderedMapIterator<K,V>
extends MapIterator<K,V>, OrderedIterator<K>
```
Defines an iterator that operates over an ordered Map.
This iterator allows both forward and reverse iteration through the map.
