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

while (rrl.hasNext()) {
     ResourceRelationship relationship = rrl.getNextResourceRelationship();
}
                

while (rrl.hasNext()) {
     ResourceRelationship[] relationships = rrl.getNextResourceRelationships(rrl.available());
}
