OSID - osid.ontology.OntologyList Service Interface Definition

Interface	osid.ontology.OntologyList
Implements	`osid.OsidList`
Used By	`osid.ontology.OntologyHierarchySession`
	`osid.ontology.OntologyLookupSession`
	`osid.ontology.OntologyQuerySession`
	`osid.ontology.OntologySearchResults`

Description	Like all `OsidLists` , `OntologyList` provides a means for accessing `Ontology` elements sequentially either one at a time or many at a time. Examples: while (ol.hasNext()) { Ontology ontology = ol.getNextOntology(); } or while (ol.hasNext()) { Ontology[] ontologies = ol.getNextOntologies(ol.available()); }
Method	getNextOntology
Description	Gets the next `Ontology` in this list.
Return	`osid.ontology.Ontology`		the next `Ontology` in this list. The `hasNext()` method should be used to test that a next `Ontology` 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	getNextOntologies
Description	Gets the next set of `Ontology` elements in this list which must be less than or equal to the return from `available()` .
Parameters	`cardinal`	`n`	the number of `Ontology` elements requested which must be less than or equal to `available()`
Return	`osid.ontology.Ontology[]`		an array of `Ontology` 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.
