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.

Constructor Detail

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 -

Method Detail

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
