public interface StepProcessorList extends OsidList
Like all OsidLists,
StepProcessorList
provides a means for accessing StepProcessor
elements
sequentially either one at a time or many at a time. Examples:
while (spl.hasNext()) { StepProcessor processor = spl.getNextStepProcessor(); }or
while (spl.hasNext()) { StepProcessor[] processors = spl.getNextStepProcessors(spl.available()); }
