OSID - osid.cataloging.CatalogNodeList Service Interface Definition

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