public interface SystemNodeList extends OsidList
Like all OsidLists,
SystemNodeList
provides a means for accessing SystemNode
elements
sequentially either one at a time or many at a time. Examples:
while (snl.hasNext()) { SystemNode node = snl.getNextSystemNode(); }or
while (snl.hasNext()) { SystemNode[] nodes = snl.getNextSystemNodes(snl.available()); }

getNextSystemNode()
Gets the next
SystemNode in this list. |
SystemNode[] |
getNextSystemNodes(long n)
Gets the next set of
SystemNode elements in this list. |
