Interface CourseEntryPeerList

All Superinterfaces:

AutoCloseable, Closeable, OsidList, OsidList

public interface CourseEntryPeerList
extends OsidList

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

while (cpl.hasNext()) {
     CourseEntryPeer peer = cpl.getNextCourseEntryPeer();
}            
  

or

while (cpl.hasNext()) {
     CourseEntryPeer[] peers = cpl.getNextCourseEntryPeers(cpl.available());
}
