OSID - osid.personnel.RealmNodeList Service Interface Definition

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