ReverseDescendantIterator (checkstyle 10.21.0 API)

java.lang.Object
- com.puppycrawl.tools.checkstyle.xpath.iterators.ReverseDescendantIterator

All Implemented Interfaces:

Closeable, AutoCloseable, net.sf.saxon.om.SequenceIterator, net.sf.saxon.tree.iter.AxisIterator
```
public class ReverseDescendantIterator
extends Object
implements net.sf.saxon.tree.iter.AxisIterator
```
Recursive-free implementation of the descendant axis iterator. Difference between this iterator and DescendantIterator in traversal order of the child nodes. In some cases it is useful to iterate from last child backwards to the first one, for example in PrecedingIterator.

public ReverseDescendantIterator(net.sf.saxon.om.NodeInfo start)
```
    Create an iterator over the "descendant" axis in reverse order.
    
    Parameters:
    
    start - the initial context node.
- Method Detail
  - pushToStack
```
private void pushToStack(net.sf.saxon.tree.iter.AxisIterator iterateAxis)
```
    Pushes all children to the stack.
    
    Parameters:
    
    iterateAxis - AxisInfo.CHILD axis iterator.
  - next
```
public net.sf.saxon.om.NodeInfo next()
```
    Get the next item in the sequence.
    
    Specified by:
    
    next in interface net.sf.saxon.tree.iter.AxisIterator
    
    Specified by:
    
    next in interface net.sf.saxon.om.SequenceIterator
    
    Returns:
    
    the next Item. If there are no more nodes, return null.
