Future<int> queryFeatureCount(
  1. {required QueryParameters queryParameters}
)

Determines the count of features that satisfy the provided query parameters.

Parameters:

  • queryParameters — The parameters of the query.

Return Value: A task that represents the asynchronous query of feature count. The value of the task result contains a uint64_t.

Implementation

Future<int> queryFeatureCount({required QueryParameters queryParameters}) {
  final taskHandle = _withThrowingErrorHandler((errorHandler) {
    return runtimecore.RT_FeatureTable_queryFeatureCount(
        _handle, queryParameters._handle, errorHandler);
  });
  return taskHandle.toFuture((element) => element.getValueAsInt()!);
}
