java.lang.Objectorg.apache.commons.collections15.iterators.AbstractMapIteratorDecorator<K,V>
public class AbstractMapIteratorDecorator<K,V>
Provides basic behaviour for decorating a map iterator with extra functionality.
All methods are forwarded to the decorated map iterator.
| Field Summary | |
|---|---|
protected MapIterator<K,V> |
iterator
The iterator being decorated |
| Constructor Summary | |
|---|---|
AbstractMapIteratorDecorator(MapIterator<K,V> iterator)
Constructor that decorates the specified iterator. |
|
| Method Summary | |
|---|---|
K |
getKey()
Gets the current key, which is the key returned by the last call to next(). |
protected MapIterator<K,V> |
getMapIterator()
Gets the iterator being decorated. |
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()
