GeographicTransformation.withSteps constructor

GeographicTransformation.withSteps(
  1. List<GeographicTransformationStep> steps
)

Create a multi-step transformation from one or more GeographicTransformationStep instances.

Use this when the multi-step transformation is known in advance. The output of each step should match the input of the following step. Then, you can use the new multi-step transformation where you would use a single-step transformation.

Parameters:

Implementation

factory GeographicTransformation.withSteps(
    List<GeographicTransformationStep> steps) {
  _initializeArcGISEnvironmentIfNeeded();
  final coreSteps =
      steps.toArray(valueType: _ElementType.geographicTransformationStep);
  final handle = _withThrowingErrorHandler((errorHandler) {
    return runtimecore.RT_GeographicTransformation_createWithSteps(
        coreSteps._handle, errorHandler);
  });
  final GeographicTransformation object =
      GeographicTransformation._withHandle(handle);
  object._steps.value.setCache(steps);
  return object;
}
