setRestartable
public void setRestartable(boolean isRestartable)
Description copied from interface:DTMAxisIterator
Set if restartable.- Specified by:
setRestartable
in interfaceDTMAxisIterator
- Overrides:
setRestartable
in classDTMAxisIteratorBase
-
setStartNode
public DTMAxisIterator setStartNode(int node)
Description copied from interface:DTMAxisIterator
Set start to END should 'close' the iterator, i.e. subsequent call to next() should return END.- Parameters:
node
- Sets the root of the iteration.- Returns:
- A DTMAxisIterator set to the start of the iteration.
-
next
public int next()
Description copied from interface:DTMAxisIterator
Get the next node in the iteration.- Returns:
- The next node handle in the iteration, or END.
-
getPosition
public int getPosition()
- Specified by:
getPosition
in interfaceDTMAxisIterator
- Overrides:
getPosition
in classDTMAxisIteratorBase
- Returns:
- The position of the current node within the set, as defined by XPath. Note that this is one-based, not zero-based.
-
getNodeByPosition
public int getNodeByPosition(int pos)
Description copied from class:DTMAxisIteratorBase
Return the node at the given position.- Specified by:
getNodeByPosition
in interfaceDTMAxisIterator
- Overrides:
getNodeByPosition
in classDTMAxisIteratorBase
- Parameters:
pos
- The position- Returns:
- The node at the given position.
-
getNode
public int getNode(int index)
-
cloneIterator
public DTMAxisIterator cloneIterator()
Description copied from class:DTMAxisIteratorBase
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 interfaceDTMAxisIterator
- Overrides:
cloneIterator
in classDTMAxisIteratorBase
- Returns:
- a deep copy of this iterator.
-
reset
public DTMAxisIterator reset()
Description copied from interface:DTMAxisIterator
Resets the iterator to the last start node.- Specified by:
reset
in interfaceDTMAxisIterator
- Overrides:
reset
in classDTMAxisIteratorBase
- Returns:
- A DTMAxisIterator which has been reset to the start node, which may or may not be the same as this iterator.
-
setMark
public void setMark()
Description copied from interface:DTMAxisIterator
Remembers the current node for the next call to gotoMark().
-
gotoMark
public void gotoMark()
Description copied from interface:DTMAxisIterator
Restores the current node remembered by setMark().
