public final class DupFilterIterator extends DTMAxisIteratorBase
Removes duplicates and sorts a source iterator. The nodes from the source are collected in an array upon calling setStartNode(). This array is later sorted and duplicates are ignored in next().- Author:

Method Detail
-
setStartNode
public DTMAxisIterator setStartNode(int node)
Set the start node for this iterator- Parameters:
node
- The start node- Returns:
- A reference to this node iterator
-
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.
-
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.
-
setRestartable
public void setRestartable(boolean isRestartable)
Description copied from interface:DTMAxisIterator
Set if restartable.- Specified by:
setRestartable
in interfaceDTMAxisIterator
- Overrides:
setRestartable
in classDTMAxisIteratorBase
-
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().
-
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.
