Method Detail
-
hasNext
public boolean hasNext()
- Specified by:
hasNext
in interfacejava.util.Iterator<INode>
-
hasPrevious
public boolean hasPrevious()
Description copied from interface:BidiIterator
Returns true if this bidi iterator has more elements when traversing in the reverse direction. (In other words, returns true if previous would return an element rather than throwing an exception.)- Specified by:
hasPrevious
in interfaceBidiIterator<INode>
- Returns:
- true if the bidi iterator has more elements when traversing in the reverse direction.
-
previous
public INode previous()
Description copied from interface:BidiIterator
Returns the previous element. This method may be called repeatedly to iterate backwards, or intermixed with calls to next to go back and forth. (Note that alternating calls to next and previous will return the same element repeatedly.)- Specified by:
previous
in interfaceBidiIterator<INode>
- Returns:
- the previous element.
