OSID - osid.control.DeviceList Service Interface Definition

Interface	osid.control.DeviceList
Implements	`osid.OsidList`
Used By	`osid.control.DeviceLookupSession`
	`osid.control.DeviceQuerySession`
	`osid.control.DeviceSearchResults`
	`osid.control.DeviceSystemSession`
	`osid.control.rules.DeviceEnablerRuleLookupSession`
Description	Like all `OsidLists`, `DeviceList` provides a means for accessing `Device` elements sequentially either one at a time or many at a time. Examples: while (dl.hasNext()) { Device device = dl.getNextDevice(); } or while (dl.hasNext()) { Device[] devices = dl.getNextDevices(dl.available()); }
Method	getNextDevice
Description	Gets the next `Device` in this list.
Return	`osid.control.Device`		the next `Device` in this list. The `hasNext()` method should be used to test that a next `Device` 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	getNextDevices
Description	Gets the next set of `Device` elements in this list. The specified amount must be less than or equal to the return from `available()`.
Parameters	`cardinal`	`n`	the number of `Device` elements requested which must be less than or equal to `available()`
Return	`osid.control.Device[]`		an array of `Device` 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.
