Class DupFilterIterator

    java.lang.Object
      org.apache.xml.dtm.ref.DTMAxisIteratorBase

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().

Constructor Detail

### DupFilterIterator

    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.
