public interface MapNodeList extends OsidList
Like all OsidLists,
MapNodeList
provides
a means for accessing MapNode
elements sequentially either
one at a time or many at a time. Examples:
while (mnl.hasNext()) { MapNode node = mnl.getNextMapNode(Node); }or
while (mnl.hasNext()) { MapNode[] nodes = ml.getNextMapNodes(mnl.available()); }

MapNode[] |
getNextMapNodes(long n)
