public interface ObjectiveBankNodeList extends OsidList
Like all OsidLists,
ObjectiveBankNodeList
provides a means for accessing ObjectiveBankNode
elements
sequentially either one at a time or many at a time. Examples:
while (obnl.hasNext()) { ObjectiveBankNode node bank = obnl.getNextObjectiveBankNode(); }or
while (obnl.hasNext()) { ObjectiveBankNode[] nodes = obnl.getNextObjectiveBankNodes(obnl.available()); }
Modifier and Type | Method and Description |

ObjectiveBankNode |
getNextObjectiveBankNode()
Gets the next
ObjectiveBankNode in this list. |
ObjectiveBankNode[] |
getNextObjectiveBankNodes(long n)
Gets the next set of
ObjectiveBankNode elements in this
list which must be less than or equal to the return from
available(). |
ObjectiveBankNode getNextObjectiveBankNode() throws OperationFailedException

hasNext()
method should be used to test that a
