java.lang.Objectorg.apache.commons.collections15.iterators.EntrySetMapIterator<K,V>
public class EntrySetMapIterator<K,V>
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);
}

| Method Summary | |
|---|---|
K |
getKey()
Gets the current key, which is the key returned by the last call to next(). |
V |
getValue()
Gets the current value, which is the value associated with the last key returned by next(). |
boolean |
hasNext()
Checks to see if there are more entries still to be iterated. |
K |
next()
Gets the next key from the Map. |
void |
remove()
Removes the last returned key from the underlying Map. |
void |
