DTMAxisIterator | cloneIterator() - Clone a
SortingIterator by cloning its source
iterator and then sharing the factory and the array of
NodeSortRecords .
|
int | getLast() - Returns the position of the last node within the iteration, as
defined by XPath.
|
int | getPosition()
|
void | gotoMark() - Restores the current node remembered by setMark().
|
int | next() - Get the next node in the iteration.
|
void | setMark() - Remembers the current node for the next call to gotoMark().
|
DTMAxisIterator | setStartNode(int node) - Set start to END should 'close' the iterator,
i.e. subsequent call to next() should return END.

getLast
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.
- getLast in interface DTMAxisIterator
- getLast in interface DTMAxisIteratorBase
- The number of nodes in this iterator (forward) or 1 (reverse).
gotoMark
public void gotoMark()
Restores the current node remembered by setMark().
- gotoMark in interface DTMAxisIterator
next
public int next()
Get the next node in the iteration.
- next in interface DTMAxisIterator
- The next node handle in the iteration, or END.
setMark
public void setMark()
Remembers the current node for the next call to gotoMark().
- setMark in interface DTMAxisIterator
setStartNode
public DTMAxisIterator setStartNode(int node)
Set start to END should 'close' the iterator,
i.e. subsequent call to next() should return END.
- setStartNode in interface DTMAxisIterator
node
- Sets the root of the iteration.
- A DTMAxisIterator set to the start of the iteration.
