Interface IListIterator
[contained in: com.sap.km.cm.repository.service.base.par - km.shared.repository.service.statemanagement_api.jar]
- All Known Subinterfaces:
- IResourceTransitionIterator
- public interface IListIterator
The IListIterator is used together with the IList . It is planned to extend it to
implement a type-safe iterator over a type-safe list of elements. All methods of the java.util.Iterator
which are not type-dependent are defined in this interface.
- See Also:
- java.util.Iterator

Method Summary |
boolean |
hasNext()
Returns true if this list iterator has more elements when traversing the list in the forward direction.
|
boolean |
hasPrevious()
Returns true if this list iterator has more elements when traversing the list in the reverse direction.
|
int |
nextIndex()
Returns the index of the element that would be returned by a subsequent call to next . |
int |
previousIndex()
Returns the index of the element that would be returned by a subsequent call to previous . |
void |
remove()
Removes the last element that was returned by next or previous (optional
operation) from the list. |
hasNext
public boolean hasNext()
- Returns true if this list iterator has more elements when traversing the list in the forward direction.
(In other words, returns true if next would return an element rather than throwing an exception).
- Returns:
- true if the list iterator has more elements when traversing the list in the forward direction
hasPrevious
public boolean hasPrevious()
- Returns true if this list iterator has more elements when traversing the list in the reverse direction.
(In other words, returns true if previous would return an element rather than throwing an
exception).
- Returns:
- true if the list iterator has more elements when traversing the list in the reverse direction
nextIndex
public int nextIndex()
- Returns the index of the element that would be returned by a subsequent call to next . (Returns list size
if the list iterator is at the end of the list).
- Returns:
- the index of the element that would be returned by a subsequent call to next , or list size if
list iterator is at end of list
previousIndex
public int previousIndex()
- Returns the index of the element that would be returned by a subsequent call to previous . (Returns -1 if
the list iterator is at the beginning of the list).
- Returns:
- the index of the element that would be returned by a subsequent call to previous , or -1 if list
iterator is at beginning of list
remove
public void remove()
- Removes the last element that was returned by next or previous (optional
operation) from the list. This call can only be made once per call to next or previous . It can be made only if
ListIterator.add has not been called after the last call to next or previous .
