aggregate method

@override Future<FdcDataAggregateResult> aggregate(FdcDataAggregateRequest request)

Calculates adapter-side aggregates over the full effective adapter result set. Subclasses that support aggregate queries override this and expose capabilities.aggregates == true.

Implementation

@override
Future<FdcDataAggregateResult> aggregate(
  FdcDataAggregateRequest request,
) async {
  throw FdcDataAdapterException(
    operation: 'aggregate',
    code: 'unsupported_adapter_operation',
    message: '$runtimeType does not support aggregate queries.',
  );
}
