Description

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

                     
                     
                     while (ol.hasNext()) {
                          Objective objective = ol.getNextObjective();
                     }
                     
                                 
                     
                
or
                     
                     
                     while (ol.hasNext()) {
                          Objective[] objectives = ol.getNextObjectives(ol.available());
                     }
                     
                                 
                     
                
MethodgetNextObjective
Description

Gets the next Objective in this list.

Returnosid.learning.Objectivethe next Objective in this list. The hasNext() method should be used to test that a next Objective is available before calling this method.
