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

                     
                     
                     while (cnl.hasNext()) {
                          CatalogNode node = cnl.getNextCatalogNode();
                     }
                     
                                 
                     
                

                     
                     
                     while (cnl.hasNext()) {
                          CatalogNode[] nodes = cnl.getNextCatalogNodes(cnl.available());
                     }
