Class CachedNodeListIterator

java.lang.Object
org.apache.xml.dtm.ref.DTMAxisIteratorBase
org.apache.xalan.xsltc.dom.CachedNodeListIterator
All Implemented Interfaces:
Cloneable, DTMAxisIterator

public final class CachedNodeListIterator extends DTMAxisIteratorBase
CachedNodeListIterator is used for select expressions in a variable or parameter. This iterator caches all nodes in an IntegerArray. Its cloneIterator() method is overridden to return an object of ClonedNodeListIterator.

      public CachedNodeListIterator(DTMAxisIterator source)
  • Method Details

    • 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
    • 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 interface DTMAxisIterator
      Overrides:
      getPosition in class DTMAxisIteratorBase
      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 interface DTMAxisIterator
      Overrides:
      getNodeByPosition in class DTMAxisIteratorBase
      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 interface DTMAxisIterator
      Overrides:
      cloneIterator in class DTMAxisIteratorBase
      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 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.
    • 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().
