Method Detail
-
setStartNode
public DTMAxisIterator setStartNode(int node)
Set context node for the iterator. This will cause the iterator to reset itself, reevaluate arguments to the function, look up nodes in the input and reinitialize its internal heap.- Specified by:
setStartNode
in interfaceDTMAxisIterator
- Overrides:
setStartNode
in classMultiValuedNodeHeapIterator
- Parameters:
node
- the context node- Returns:
- A
DTMAxisIterator
set to the start of the iteration.
-
next
public int next()
Get the next node in the iteration.- Specified by:
next
in interfaceDTMAxisIterator
- Overrides:
next
in classMultiValuedNodeHeapIterator
- Returns:
- The next node handle in the iteration, or END.
-
reset
public DTMAxisIterator reset()
Resets the iterator to the last start node.- Specified by:
reset
in interfaceDTMAxisIterator
- Overrides:
reset
in classMultiValuedNodeHeapIterator
- Returns:
- A DTMAxisIterator, which may or may not be the same as this iterator.
-
getLast
public int getLast()
Returns the number of nodes in this iterator.- Specified by:
getLast
in interfaceDTMAxisIterator
- Overrides:
getLast
in classDTMAxisIteratorBase
- Returns:
- the number of nodes
-
getNodeByPosition
public int getNodeByPosition(int position)
Return the node at the given position.- Specified by:
getNodeByPosition
in interfaceDTMAxisIterator
- Overrides:
getNodeByPosition
in classDTMAxisIteratorBase
- Parameters:
position
- The position- Returns:
- The node at the given position.
