- public interface IterableMap
- extends Map
Defines a map that can be iterated directly without needing to create an entry set.
A map iterator is an efficient way of iterating over maps.
There is no need to access the entry set or cast to Map Entry objects.
IterableMap map = new HashedMap();
MapIterator it = map.mapIterator();
while (it.hasNext()) {
Object key = it.next();
Object value = it.getValue();
it.setValue("newValue");
}
