public interface ObjectiveNodeList extends OsidList
Like all OsidLists,
ObjectiveNodeList
provides a means for accessing ObjectiveNode
elements
sequentially either one at a time or many at a time. Examples:
while (onl.hasNext()) { ObjectiveNode node = onl.getNextObjectiveNode(); }or
while (onl.hasNext()) { ObjectiveNode[] nodes = onl.getNextObjectiveNodes(onl.available()); }
Modifier and Type | Method and Description |

ObjectiveNode |
getNextObjectiveNode()
Gets the next
ObjectiveNode in this list. |
ObjectiveNode[] |
getNextObjectiveNodes(long n)
Gets the next set of
ObjectiveNode elements in this
list which must be less than or equal to the number returned from
available(). |
ObjectiveNode getNextObjectiveNode() throws OperationFailedException
