public interface ResourceNodeList extends OsidList
Like all OsidLists,
ResourceNodeList
provides a means for accessing ResourceNode
elements
sequentially either one at a time or many at a time. Examples:
while (rnl.hasNext()) { ResourceNode node = rnl.getNextResourceNode(); }or
while rnl.hasNext()) { ResourceNode[] nodes = rnl.getNextResourceNodes(rnl.available()); }

getNextResourceNode()
Gets the next
