public DTMAxisIterator cloneIterator()
Returns a deep copy of this iterator. Cloned iterators may not be restartable. The iterator being cloned may or may not become non-restartable as a side effect of this operation.
- Specified by:
- cloneIterator in interface DTMAxisIterator
- Overrides:
- cloneIterator in interface DTMAxisIteratorBase
- Returns:
- a deep copy of this iterator.
public int getLast()
Returns the position of the last node within the iteration, as defined by XPath. In a forward iterator, I believe this equals the number of nodes which this iterator will yield. In a reverse iterator, I believe it should return 1 (since the "last" is the first produced.) This may be an expensive operation when called the first time, since it may have to iterate through a large part of the document to produce its answer.
- Specified by:
- getLast in interface DTMAxisIterator
- Overrides:
- getLast in interface DTMAxisIteratorBase
- Returns:
- The number of nodes in this iterator (forward) or 1 (reverse).
public int getPosition()
- Specified by:
- getPosition in interface DTMAxisIterator
- Overrides:
- getPosition in interface DTMAxisIteratorBase
- Returns:
- The position of the current node within the set, as defined by XPath. Note that this is one-based, not zero-based.
public DTMAxisIterator reset()
- Specified by:
- reset in interface DTMAxisIterator
- Overrides:
- reset in interface DTMAxisIteratorBase
- Returns:
- A DTMAxisIterator which has been reset to the start node, which may or may not be the same as this iterator.
public void setRestartable(boolean isRestartable)
- Specified by:
- setRestartable in interface DTMAxisIterator
- Overrides:
- setRestartable in interface DTMAxisIteratorBase
public DTMAxisIterator setStartNode(int node)
- Specified by:
- setStartNode in interface DTMAxisIterator
