public interface LogNodeList extends OsidList
Like all OsidLists,
LogNodeList
provides
a means for accessing LogNode
elements sequentially either
one at a time or many at a time. Examples:
while (lnl.hasNext()) { LogNode node = lnl.getNextLogNode(); }or
while (lnl.hasNext()) { LogNode[] nodes = lnl.getNextLogNodes(lnl.available()); }

LogNode[] |
getNextLogNodes(long n)
Gets the next set of
LogNode elements in this list. |
