    ReturnValues Property
    In This Topic
    Gets or sets the list of return values.
    Syntax
    public List<PointCloudReturnType> ReturnValues {get; set;}
    Public Property ReturnValues As List(Of PointCloudReturnType)
    Example
    Set a Filter for PointCloudSceneLayer
    //Must be called on the MCT
    //var pcsl = ...;
    //Retrieve the available classification codes
    //At 2.x - var dict = pcsl.QueryAvailableClassCodesAndLabels();
    var dict = pcsl.GetAvailableClassCodesAndLabels();
    
    //Filter out low noise and unclassified (7 and 1 respectively)
    //consult https://pro.arcgis.com/en/pro-app/help/data/las-dataset/storing-lidar-data.htm
    var filterDef = new PointCloudFilterDefinition()
    {
      ClassCodes = dict.Keys.Where(c => c != 7 && c != 1).ToList(),
      ReturnValues = new List<PointCloudReturnType> { 
                             PointCloudReturnType.FirstOfMany }
    };
    //apply the filter
    pcsl.SetFilters(filterDef.ToCIM());
    
    Get the filters for PointCloudSceneLayer
    //Must be called on the MCT
    //var pcsl = ...;
    IReadOnlyList<CIMPointCloudFilter> updatedFilter = pcsl.GetFilters();
    foreach (var filter in updatedFilter)
    {
      //There is either 0 or 1 of each
      if (filter is CIMPointCloudReturnFilter returnFilter)
      {
        PointCloudFilterDefinition pcfl = PointCloudFilterDefinition.FromCIM(updatedFilter);
        List<PointCloudReturnType> updatedReturnValues = pcfl.ReturnValues;
    
      }
      if (filter is CIMPointCloudValueFilter classCodesFilter)
      {
        // do something
      }
    
      if (filter is CIMPointCloudBitFieldFilter classFlagsFilter)
      {
        // do something
      }
    }
