Interface IListIterator

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.

Method Detail

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 .
