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

while (ccl.hasNext()) {
     CourseCatalog catalog = ccl.getNextCourseCatalog();
}
                

while (ccl.hasNext()) {
     CourseCatalog[] catalogs = ccl.getNextCourseCatalogs(ccl.available());
}
