Object | getKey() - Gets the current key, which is the key returned by the last call
to
next() .
|
protected MapIterator | getMapIterator() - Gets the iterator being decorated.
|
Object | 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.
|
Object | next() - Gets the next key from the
Map .
|
void | remove() - Removes the last returned key from the underlying
Map (optional operation).
|
Object | setValue(Object obj) - Sets the value associated with the current key (optional operation).

iterator
protected final MapIterator iterator
The iterator being decorated
AbstractMapIteratorDecorator
public AbstractMapIteratorDecorator(MapIterator iterator)
Constructor that decorates the specified iterator.
iterator
- the iterator to decorate, must not be null
getKey
public Object getKey()
Gets the current key, which is the key returned by the last call
to next()
.
- getKey in interface MapIterator
getMapIterator
protected MapIterator getMapIterator()
Gets the iterator being decorated.
getValue
public Object getValue()
Gets the current value, which is the value associated with the last key
returned by next()
.
- getValue in interface MapIterator
hasNext
public boolean hasNext()
Checks to see if there are more entries still to be iterated.
- hasNext in interface MapIterator
true
if the iterator has more elements
next
public Object next()
Gets the next key from the Map
.
- next in interface MapIterator
- the next key in the iteration
remove
public void remove()
Removes the last returned key from the underlying
Map
(optional operation).
This method can be called once per call to
next()
.
- remove in interface MapIterator
setValue
public Object setValue(Object obj)
Sets the value associated with the current key (optional operation).
- setValue in interface MapIterator
