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.

        if (ptr.getNode() != null) {
            // There are some nodes to load from


            JXPathContext repeaterContext = jctx.getRelativeContext(ptr);
            // build a jxpath iterator for pointers
            Iterator rowPointers = repeaterContext.iteratePointers(this.rowPath);


            //iterate through it
            int rowNum = 0;
            while (rowPointers.hasNext()) {
                // Get a row. It is created if needed (depends on clearOnLoad)
