This class implements an optimized iterator for "key()" patterns. It uses a KeyIterator to walk the source tree and incrementally build a list of nodes that match a given key name, match pattern and value.
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.

addNode(int node)
Add a node matching this ref to the cached nodes for this iterator |
java.lang.Object |
clone()
Get a cloned LocPathIterator that holds the same position as this iterator. |
void |
detach()
Detaches the iterator from the set which it iterated over, releasing any computational resources and placing the iterator in the INVALID state. |
