All Implemented Interfaces:

java.lang.Cloneable, DTMAxisIterator
```
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().

public DupFilterIterator(DTMAxisIterator source)
```
- 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 interface DTMAxisIterator
    
    Overrides:
    
    cloneIterator in class DTMAxisIteratorBase
    
    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 interface DTMAxisIterator
    
    Overrides:
    
    setRestartable in class DTMAxisIteratorBase
  - 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 interface DTMAxisIterator
    
    Overrides:
    
    reset in class DTMAxisIteratorBase
    
    Returns:
    
    A DTMAxisIterator which has been reset to the start node, which may or may not be the same as this iterator.
