    java.lang.Object
      org.apache.xml.dtm.ref.DTMAxisIteratorBase
          org.apache.xalan.xsltc.dom.SimpleResultTreeImpl.SimpleIterator

All Implemented Interfaces:
  java.lang.Cloneable, DTMAxisIterator

Enclosing class:
  SimpleResultTreeImpl

    public final class SimpleResultTreeImpl.SimpleIterator

extends DTMAxisIteratorBase

The SimpleIterator is designed to support the nodeset() extension function. It has a traversal direction parameter. The DOWN direction is used for child and descendant axes, while the UP direction is used for parent and ancestor axes. This iterator only handles two nodes (RTF_ROOT and RTF_TEXT). If the type is set, it will also match the node type with the given type.

Constructor Summary
`SimpleResultTreeImpl.SimpleIterator()`
`SimpleResultTreeImpl.SimpleIterator(int direction)`
`SimpleResultTreeImpl.SimpleIterator(int direction, int type)`

Method Summary
`void` `gotoMark()` Restores the current node remembered by setMark().
`int` `next()` Get the next node in the iteration.
`void` `setMark()` Remembers the current node for the next call to gotoMark().
`DTMAxisIterator` `setStartNode(int nodeHandle)` Set start to END should 'close' the iterator, i.e. subsequent call to next() should return END.

Method Detail

### 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.

### setStartNode

    public DTMAxisIterator setStartNode(int nodeHandle)

  Description copied from interface: `DTMAxisIterator`
  Set start to END should 'close' the iterator, i.e. subsequent call to next() should return END.

  Parameters:
    `nodeHandle` - Sets the root of the iteration.
  Returns:
    A DTMAxisIterator set to the start of the iteration.

### 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().
