watchSingle method

  1. @override
Stream<DeviceResourceAuditData> watchSingle({
  1. bool distinct = true,
})
inherited

Creates an auto-updating stream of this statement, similar to watch. However, it is assumed that the query will only emit one result, so instead of returning a Stream<List<D>>, this returns a Stream<D>. If, at any point, the query emits no or more than one rows, an error will be added to the stream instead.

The distinct parameter (enabled by default) controls whether to generate a SELECT DISTINCT query, removing duplicates from the result.

Implementation

@override
Stream<$ActiveDataclass> watchSingle({bool distinct = true}) =>
    watch(distinct: distinct).transform(singleElements());
