OSID - osid.grading.GradebookNodeList Service Interface Definition

Interface	osid.grading.GradebookNodeList
Implements	`osid.OsidList`
Used By	`osid.grading.GradebookNode`
Description	Like all `OsidLists`, `GradebookNodeList` provides a means for accessing `GradebookNode` elements sequentially either one at a time or many at a time. Examples: while (gnl.hasNext()) { GradebookNode node = gnl.getNextGradebookNode(); } or while (gnl.hasNext()) { GradebookNode[] nodes = gnl.getNextGradebookNodes(gnl.available()); }
Method	getNextGradebookNode
Description	Gets the next `GradebookNode` in this list.
Return	`osid.grading.GradebookNode`		the next `GradebookNode` in this list. The `hasNext()` method should be used to test that a next `GradebookNode` 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	getNextGradebookNodes
Description	Gets the next set of `GradebookNode` elements in this list which must be less than or equal to the return from `available()`.
Parameters	`cardinal`	`n`	the number of `GradebookNode` elements requested which must be less than or equal to `available()`
Return	`osid.grading.GradebookNode[]`		an array of `GradebookNode` 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
