java.lang.Objectorg.apache.commons.collections.iterators.AbstractOrderedMapIteratorDecorator
public class AbstractOrderedMapIteratorDecorator
Provides basic behaviour for decorating an ordered map iterator with extra functionality.
All methods are forwarded to the decorated map iterator.
| Field Summary | |
|---|---|
protected OrderedMapIterator |
iterator
The iterator being decorated |
| Constructor Summary | |
|---|---|
AbstractOrderedMapIteratorDecorator(OrderedMapIterator iterator)
Constructor that decorates the specified iterator. |
|
| Method Summary | |
|---|---|
java.lang.Object |
getKey()
Gets the current key, which is the key returned by the last call to next(). |
protected OrderedMapIterator |
getOrderedMapIterator()
Gets the iterator being decorated. |
java.lang.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. |
boolean |
hasPrevious()
Checks to see if there is a previous element that can be iterated to. |
java.lang.Object |
next()
