Future<StatisticsQueryResult> queryStatistics(
  1. StatisticsQueryParameters statisticsQueryParameters
)

  • statisticsQueryParameters — The parameters that define the statistics, fields, and features to be used for the query.

Return Value: A task that represents the asynchronous query statistics operation. The value of the task result contains a StatisticsQueryResult object.

Implementation

Future<StatisticsQueryResult> queryStatistics(
  StatisticsQueryParameters statisticsQueryParameters,
) {
  final taskHandle = _withThrowingErrorHandler((errorHandler) {
    return runtimecore.RT_FeatureTable_queryStatistics(
      _handle,
      statisticsQueryParameters._handle,
      errorHandler,
    );
  });
  return taskHandle.toFuture(
    (element) => element.getValueAsStatisticsQueryResult()!,
  );
}
