Interface IterableMap

All Superinterfaces:

java.util.Map

All Known Implementing Classes:

AbstractHashedMap, AbstractReferenceMap, ReferenceMap

public interface IterableMap
extends java.util.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");
 }
