sub abstract method

Future<HGrid> sub(
  1. List<HRef> ids, {
  2. bool checked = true,
})

Add a list of records to the subscription list and return their current representation.

If checked is true and any one of the ids cannot be resolved then raise UnknownRecException for first id not resolved. If checked is false, then each id not found has a row where every cell is null.

The HGrid that is returned must contain metadata entries for 'watchId' and 'lease'.

Implementation

Future<HGrid> sub(List<HRef> ids, {bool checked = true});
