  53  * @can_poll_for_media: Returns %TRUE if the #GDrive is capable of manually polling for media change.
  54  * @can_eject: Returns %TRUE if the #GDrive can eject media.
  55  * @eject: Ejects a #GDrive.
  56  * @eject_finish: Finishes an eject operation.
  57  * @poll_for_media: Poll for media insertion/removal on a #GDrive.
  58  * @poll_for_media_finish: Finishes a media poll operation.
  59  * @get_identifier: Returns the identifier of the given kind, or %NULL if
  60  *    the #GDrive doesn't have one.
  61  * @enumerate_identifiers: Returns an array strings listing the kinds
  62  *    of identifiers which the #GDrive has.
  63  * @get_start_stop_type: Gets a #GDriveStartStopType with details about starting/stopping the drive. Since 2.22.
  64  * @can_stop: Returns %TRUE if a #GDrive can be stopped. Since 2.22.
