Examples of org.apache.commons.jxpath.JXPathContext.iteratePointers()

org.apache.commons.jxpath.JXPathContext.iteratePointers()
Traverses the xpath and returns an Iterator of Pointers. A Pointer provides easy access to a property. If the xpath matches no properties in the graph, the Iterator be empty, but not null.
