Interface SubjectNodeList

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

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

while (snl.hasNext()) {
     SubjectNode node = snl.getNextSubjectNode();
}
or 
while (snl.hasNext()) {
     SubjectNode[] nodes = snl.getNextSubjectNodes(snl.available());
}
