Interface DurationList

All Superinterfaces:
AutoCloseable, Closeable, OsidList, OsidList
public interface DurationList extends OsidList

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

while (dl.hasNext()) {
     Duration duration = dl.getNextDuration();
}
or 
while dl.hasNext()) {
     Duration[] durations = dl.getNextDurations(dl.available());
}
