SimpleResultTreeImpl.SimpleIterator (Xalan-Java 2.7.2)

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.

Method Summary

All Methods Instance Methods Concrete Methods
Modifier and Type	Method	Description
`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.

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

    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().
