IsControllerDatasetSupported Method

In This Topic

Gets a value indicating whether this Table supports the concept of controller datasets. This method must be called on the MCT. Use QueuedTask.Run.

Syntax

Visual Basic (Declaration)
C#

Public Function IsControllerDatasetSupported() As Boolean

public bool IsControllerDatasetSupported()

Return Value

true if this table supports controller datasets; otherwise, false. Supporting controller datasets does not necessarily mean that a controller dataset exists, just that the GetControllerDatasets method can be called without fear that it will throw an exception.

Example

Get parcel fabric from table

{
  var parcelFabricDataset = await QueuedTask.Run(() =>
  {
    ParcelFabric myParcelFabricDataset = null;
    if (table.IsControllerDatasetSupported())
    {
      // Tables can belong to multiple controller datasets, but at most one of them will be a parcel fabric

      IReadOnlyList<Dataset> controllerDatasets = table.GetControllerDatasets();
      foreach (Dataset controllerDataset in controllerDatasets)
      {
        if (controllerDataset is ParcelFabric)
        {
          myParcelFabricDataset = controllerDataset as ParcelFabric;
        }
        else
        {
          controllerDataset.Dispose();
        }
      }
    }
    return myParcelFabricDataset;
  });
}

Get a Utility Network from a Table

{
  static UtilityNetwork GetUtilityNetworkFromTable()
  {
    UtilityNetwork utilityNetwork = null;

    Table table = MapView.Active.Map.GetStandaloneTablesAsFlattenedList().First().GetTable();

    // This routine obtains a utility network from a table
    if (table.IsControllerDatasetSupported())
    {
      // Tables can belong to multiple controller datasets, but at most one of them will be a UtilityNetwork
      IReadOnlyList<Dataset> controllerDatasets = table.GetControllerDatasets();

      foreach (Dataset controllerDataset in controllerDatasets)
      {
        if (controllerDataset is UtilityNetwork)
        {
          utilityNetwork = controllerDataset as UtilityNetwork;
        }
        else
        {
          controllerDataset.Dispose();
        }
      }
    }
    return utilityNetwork;
  }
}

Get a Utility Network from a Layer

{
  static UtilityNetwork GetUtilityNetworkFromLayer(Layer unLayer)
  {
    UtilityNetwork utilityNetwork = null;

    Layer layer = MapView.Active.Map.GetLayersAsFlattenedList().First();

    // This routine obtains a utility network from a FeatureLayer, SubtypeGroupLayer, or UtilityNetworkLayer
    if (layer is UtilityNetworkLayer)
    {
      UtilityNetworkLayer utilityNetworkLayer = layer as UtilityNetworkLayer;
      utilityNetwork = utilityNetworkLayer.GetUtilityNetwork();
    }

    else if (layer is SubtypeGroupLayer)
    {
      CompositeLayer compositeLayer = layer as CompositeLayer;
      utilityNetwork = GetUtilityNetworkFromLayer(compositeLayer.Layers.First());
    }

    else if (layer is FeatureLayer)
    {
      FeatureLayer featureLayer = layer as FeatureLayer;
      using (FeatureClass featureClass = featureLayer.GetFeatureClass())
      {
        if (featureClass.IsControllerDatasetSupported())
        {
          IReadOnlyList<Dataset> controllerDatasets = new List<Dataset>();
          controllerDatasets = featureClass.GetControllerDatasets();
          foreach (Dataset controllerDataset in controllerDatasets)
          {
            if (controllerDataset is UtilityNetwork)
            {
              utilityNetwork = controllerDataset as UtilityNetwork;
            }
            else
            {
              controllerDataset.Dispose();
            }
          }
        }
      }
    }
    return utilityNetwork;
  }
}
