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

while (gccl.hasNext()) {
     GradebookColumnCalculation calculation = gccl.getNextGradebookColumnCalculation();
}
                

while (gccl.hasNext()) {
     GradebookColumnCalculation[] calculations = gccl.getNextGradebookColumnCalculations(gccl.available());
}
