public interface ActivityNodeList extends OsidList
Like all OsidLists,
ActivityNodeList
provides a means for accessing ActivityNode
elements
sequentially either one at a time or many at a time. Examples:
while (anl.hasNext()) { ActivityNode node = anl.getNextActivityNode(); }or
while (anl.hasNext()) { ActivityNode[] nodes = anl.getNextActivityNodes(anl.available()); }
