- public class ChildIterator
- extends LocPathIterator
This class implements an optimized iterator for
"node()" patterns, that is, any children of the
context node.
This class is based on an implementation from the Apache XML
Project. In future releases the XML parser, XSLT processor, and
associated classes will likely be updated to be based on a later
version of the Apache implementations. Since Apache does not guarantee
backwards compatibility between versions of their software, we cannot
guarantee backwards compatibility of any of the classes contained in
the weblogic.apache package or sub-packages.

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!
- Parameters:
xctxt
- The XPath runtime context.- Returns:
- the first node out of the nodeset, or DTM.NULL.
- Overrides:
- asNode in class LocPathIterator
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.
- Returns:
- The next
Node
in the set being iterated over, or
null
if there are no more members in that set. - Overrides:
- nextNode in class LocPathIterator
getAxis
public int getAxis()
- Returns the axis being iterated, if it is known.
- Returns:
- Axis.CHILD, etc., or -1 if the axis is not known or is of multiple
types.
- Overrides:
- getAxis in class LocPathIterator
