OSID - osid.course.TermNodeList Service Interface Definition

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