   *     metadata will be returned.
   * @param maxResults The maximum number of queue results to retrieve.
   * @param continuationToken A {@link ResultContinuation} object that represents a continuation
   *     token returned by a previous listing operation.
   * @param options A {@link QueueRequestOptions} object that specifies any additional options for
   *     the request. Specifying <code>null</code> will use the default request options from the

   *     iterable collection of {@link CloudQueue} objects that represent the requested queues in
   *     the storage service.
   * @throws StorageException If a storage service error occurred during the operation.
