- 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.

ChildIterator
public ChildIterator(Compiler compiler,
int opPos,
int analysis)
throws javax.xml.transform.TransformerException
- Create a ChildIterator object.
- Parameters:
compiler
- A reference to the Compiler that contains the op map.opPos
- The position within the op map, which contains the
location path expression for this itterator.
NEEDSDOC @param analysis- Throws:
- javax.xml.transform.TransformerException -
nextNode
public org.w3c.dom.Node nextNode()
throws org.w3c.dom.DOMException
- 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. - Throws:
- org.w3c.dom.DOMException - INVALID_STATE_ERR: Raised if this method is called after the
detach
method was invoked. - Overrides:
- nextNode in class LocPathIterator
