public interface ObjectiveList extends OsidList
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()); }

Objective |
getNextObjective()
Gets the next
Objective in this list. |
Objective[] |
getNextObjectives(long n)
Gets the next set of

which must be less than or equal to the number returned from
available(). |
