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

while (gcbfl.hasNext()) {
     GradebookColumnBatchForm form = gcbfl.getNextGradebookColumnBatchForm();
}
                

while (gcbfl.hasNext()) {
     GradebookColumnBatchForm[] forms = gcbfl.getNextGradebookColumnBatchForms(gcbfl.available());
}
