Interface AvailabilityPeerList

All Superinterfaces:

AutoCloseable, Closeable, OsidList, OsidList

public interface AvailabilityPeerList
extends OsidList

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

while (apl.hasNext()) {
     AvailabilityPeer peer = apl.getNextAvailabilityPeer();
}            
  

or

while (apl.hasNext()) {
     AvailabilityPeer[] peers = apl.getNextAvailabilityPeers(apl.available());
}
