Description	Like all `OsidLists`, `SystemList` provides a means for accessing `System` elements sequentially either one at a time or many at a time. Examples: while (sl.hasNext()) { System system = sl.getNextSystem(); } or while (sl.hasNext()) { System[] systems = sl.getNextSystems(sl.available()); }
Method	getNextSystem
Description	Gets the next `System` in this list.
Return	`osid.control.System`		the next `System` in this list. The `hasNext()` method should be used to test that a next `System` 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	getNextSystems
Description	Gets the next set of `System` elements in this list. The specified amount must be less than or equal to the return from `available()`.
Parameters	`cardinal`	`n`	the number of `System` elements requested which must be less than or equal to `available()`
Return	`osid.control.System[]`		an array of `System` 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.
