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

                     
                     
                     while (cl.hasNext()) {
                          Catalog catalog = cl.getNextCatalog();
                     }
                     
                                 
                     
                

                     
                     
                     while (cl.hasNext()) {
                          Catalog[] catalogs = cl.getNextCatalogs(cl.available());
                     }
