Method Summary

All Methods Instance Methods Concrete Methods
Modifier and Type	Method	Description
`int`	`asNode(XPathContext xctxt)`	Return the first node out of the nodeset, if this expression is a nodeset expression.
`int`	`getAxis()`	Returns the axis being iterated, if it is known.
`int`	`nextNode()`	Returns the next node in the set and advances the position of the iterator in the set.

- Method Detail
  - asNode
```
public int asNode(XPathContext xctxt)
           throws javax.xml.transform.TransformerException
```
    Return the first node out of the nodeset, if this expression is a nodeset expression. This is the default implementation for nodesets.
    WARNING: Do not mutate this class from this function!
    
    Overrides:
    
    asNode in class LocPathIterator
    
    Parameters:
    
    xctxt - The XPath runtime context.
    
    Returns:
    
    the first node out of the nodeset, or DTM.NULL.
    
    Throws:
    
    javax.xml.transform.TransformerException
  - nextNode
```
public int nextNode()
```
    Returns the next node in the set and advances the position of the iterator in the set. After a NodeIterator is created, the first call to nextNode() returns the first node in the set.
    
    Specified by:
    
    nextNode in interface DTMIterator
    
    Specified by:
    
    nextNode in class LocPathIterator
    
    Returns:
    
    The next Node in the set being iterated over, or null if there are no more members in that set.
  - getAxis
```
public int getAxis()
```
    Returns the axis being iterated, if it is known.
    
    Specified by:
    
    getAxis in interface DTMIterator
    
    Overrides:
    
    getAxis in class LocPathIterator
    
    Returns:
    
    Axis.CHILD, etc., or -1 if the axis is not known or is of multiple types.
