OSID - osid.ontology.OntologyNodeList Service Interface Definition

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