public interface StepConstrainerList extends OsidList
Like all OsidLists,
StepConstrainerList
provides a means for accessing StepConstrainer
elements
sequentially either one at a time or many at a time. Examples:
while (scl.hasNext()) { StepConstrainer constrainer = scl.getNextStepConstrainer(); }or
while (scl.hasNext()) { StepConstrainer[] constrainers = scl.getNextStepConstrainers(scl.available()); }
