OSID - osid.learning.ObjectiveBankNodeList Service Interface Definition

Interface	osid.learning.ObjectiveBankNodeList
Implements	`osid.OsidList`
Used By	`osid.learning.ObjectiveBankNode`
Description	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()); }
Method	getNextObjectiveBankNode
Description	Gets the next `ObjectiveBankNode` in this list.
Return	`osid.learning.ObjectiveBankNode`		the next `ObjectiveBankNode` in this list. The `hasNext()` method should be used to test that a next `ObjectiveBankNode` is available before calling this method.
Errors	ILLEGAL_STATE		no more elements available in this list
Errors	OPERATION_FAILED		unable to complete request
Compliance	`mandatory`		This method must be implemented.
Method	getNextObjectiveBankNodes
Description	Gets the next set of `ObjectiveBankNode` elements in this list which must be less than or equal to the return from `available()`.
Parameters	`cardinal`	`n`	the number of `ObjectiveBankNode` elements requested which must be less than or equal to `available()`
Return	`osid.learning.ObjectiveBankNode[]`		an array of `ObjectiveBankNode` elements. The length of the array is less than or equal to the number specified.
Errors	ILLEGAL_STATE		no more elements available in this list
Errors	OPERATION_FAILED		unable to complete request
Compliance	`mandatory`		This method must be implemented.
