OSID - osid.mapping.MapNodeList Service Interface Definition

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