```
public ReverseNodeArrayIterator(Item[] items,
                                int start,
                                int end)
```
    Create a reverse iterator over a slice of an array
    
    Parameters:
    
    items - The array of items
    
    start - The first item in the array to be be used (this will be the last one in the resulting iteration). Zero-based.
    
    end - The item after the last one in the array to be used (this will be the first one to be returned by the iterator). Zero-based.
- Method Detail
  - moveNext
```
public boolean moveNext()
```
    Move to the next node, without returning it. Returns true if there is a next node, false if the end of the sequence has been reached. After calling this method, the current node may be retrieved using the current() function.
    
    Specified by:
    
    moveNext in interface AxisIterator
  - iterateAxis
```
public AxisIterator iterateAxis(byte axis,
                                NodeTest test)
```
    Return an iterator over an axis, starting at the current node.
    
    Specified by:
    
    iterateAxis in interface AxisIterator
    
    Parameters:
    
    axis - the axis to iterate over, using a constant such as Axis.CHILD
    
    test - a predicate to apply to the nodes before returning them.
    
    Throws:
    
    java.lang.NullPointerException - if there is no current node
  - atomize
```
public Value atomize()
              throws XPathException
```
    Return the atomized value of the current node.
    
    Specified by:
    
    atomize in interface AxisIterator
    
    Returns:
    
    the atomized value.
    
    Throws:
    
    java.lang.NullPointerException - if there is no current node
    
    XPathException
  - getStringValue
```
public java.lang.CharSequence getStringValue()
```
    Return the string value of the current node.
    
    Specified by:
    
    getStringValue in interface AxisIterator
    
    Returns:
    
    the string value, as an instance of CharSequence.
    
    Throws:
    
    java.lang.NullPointerException - if there is no current node
  - getAnother
```
public SequenceIterator getAnother()
```
    Get another iterator over the same items
    
    Specified by:
    
    getAnother in interface SequenceIterator
    
    Specified by:
    
    getAnother in interface UnfailingIterator
    
    Overrides:
    
    getAnother in class ReverseArrayIterator
    
    Returns:
    
    another iterator over the same items, positioned at the start of the sequence
  - getReverseIterator
```
public SequenceIterator getReverseIterator()
```
    Get an iterator that processes the same items in reverse order. Since this iterator is processing the items backwards, this method returns an ArrayIterator that processes them forwards.
    
    Specified by:
    
    getReverseIterator in interface ReversibleIterator
    
    Overrides:
    
    getReverseIterator in class ReverseArrayIterator
    
    Returns:
    
    a new ArrayIterator
