queryExtent method

Future<Envelope> queryExtent(
  1. QueryParameters queryParameters
)

Determines the minimum bounding envelope that contains features satisfying the provided query parameters.

If no features meet the query criteria, an empty envelope is returned.

Parameters:

  • queryParameters — The parameters of the query.

Return Value: A task that represents the asynchronous query of feature extent. The value of the task result contains an Envelope object.

Implementation

Future<Envelope> queryExtent(
  QueryParameters queryParameters,
) {
  final taskHandle = _withThrowingErrorHandler((errorHandler) {
    return runtimecore.RT_FeatureTable_queryExtent(
      _handle,
      queryParameters._handle,
      errorHandler,
    );
  });
  return taskHandle.toFuture(
    (element) => element.getValueAsEnvelope()!,
  );
}
