Interface GradebookColumnCalculationList

All Superinterfaces:

java.lang.AutoCloseable, java.io.Closeable, OsidList

public interface GradebookColumnCalculationList
extends OsidList

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();
       }
       
                   
       
  

or

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

Method Detail

getNextGradebookColumnCalculation

GradebookColumnCalculation getNextGradebookColumnCalculation()
                                                             throws OperationFailedException

Gets the next GradebookColumnCalculation in this list.

Returns:

the next GradebookColumnCalculation in this list. The hasNext() method should be used to test that a next GradebookColumnCalculation is available before calling this method.

Throws:

IllegalStateException - no more elements available in this list

OperationFailedException - unable to complete request

Compliance:

mandatory - This method must be implemented.

getNextGradebookColumnCalculations

GradebookColumnCalculation[] getNextGradebookColumnCalculations(long n)
                                                                throws OperationFailedException

Gets the next set of GradebookColumnCalculation elements in this list which must be less than or equal to the return from available().

Parameters:

n - the number of GradebookColumnCalculation elements requested which must be less than or equal to available()

Returns:

an array of GradebookColumnCalculation elements. The length of the array is less than or equal to the number specified.
