Description	Like all `OsidLists` , `QueueProcessorList` provides a means for accessing `QueueProcessor` elements sequentially either one at a time or many at a time. Examples: while (qpl.hasNext()) { QueueProcessor processor = qpl.getNextQueueProcessor(); } or while (qpl.hasNext()) { QueueProcessor[] processors = qpl.getNextQueueProcessors(qpl.available()); }
Method	getNextQueueProcessor
Description	Gets the next `QueueProcessor` in this list.
Return	`osid.tracking.rules.QueueProcessor`		the next `QueueProcessor` in this list. The `hasNext()` method should be used to test that a next `QueueProcessor` is available before calling this method.

Errors	OPERATION_FAILED		unable to complete request
Compliance	`mandatory`		This method must be implemented.
Method	getNextQueueProcessors
Description	Gets the next set of `QueueProcessor` elements in this list. The specified amount must be less than or equal to the return from `available()` .
Parameters	`cardinal`	`n`	the number of `QueueProcessor` elements requested which must be less than or equal to `available()`
Return	`osid.tracking.rules.QueueProcessor[]`		an array of `QueueProcessor` 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
