Like all OsidLists, GradebookNodeList provides a means for accessing GradebookNode elements sequentially either one at a time or many at a time. Examples:

                     
                     
                     while (gnl.hasNext()) {
                          GradebookNode node = gnl.getNextGradebookNode();
                     }
                     
                                 
                     
                

                     
                     
                     while (gnl.hasNext()) {
                          GradebookNode[] nodes = gnl.getNextGradebookNodes(gnl.available());
                     }
