Interface ParticipantList

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

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

while (pl.hasNext()) {
     Participant participant = pl.getNextParticipant();
}
or 
while (pl.hasNext()) {
     Participant[] participants = pl.getNextParticipants(pl.available());
}
