java.lang.Objectorg.apache.commons.collections.iterators.EntrySetMapIterator
public class EntrySetMapIterator
Implements a MapIterator using a Map entrySet.
Reverse iteration is not supported.
MapIterator it = map.mapIterator();
while (it.hasNext()) {
Object key = it.next();
Object value = it.getValue();
it.setValue(newValue);
}
