Syntax
Exceptions
ExceptionDescription
This method or property must be called within the lambda passed to QueuedTask.Run.
Example
Check Whether A Graph Type has a Spatial Property
//Use GetDocumentEntityTypeName(KnowledgeGraphDataModel kg_dm) from
//the 'Get Whether KG Has a Document Type' snippet to
//get the documentNameType parameter
protected bool HasGeometry(KnowledgeGraphNamedObjectType kg_named_obj)
{
  var props = kg_named_obj.GetProperties();
  return props.Any(prop => prop.FieldType == FieldType.Geometry);
}
Get All KnowledgeGraph Graph Types
QueuedTask.Run(() =>
{
  //Create a connection properties
  var kg_props =
      new KnowledgeGraphConnectionProperties(new Uri(url));
  using (var kg = new KnowledgeGraph(kg_props))
  {
    //Get the KnowledgeGraph Data Model
    using (var kg_datamodel = kg.GetDataModel())
    {
      var entities = kg_datamodel.GetEntityTypes();
      var relationships = kg_datamodel.GetRelationshipTypes();
      var provenance = kg_datamodel.GetMetaEntityTypes();

      var all_graph_types = new List<KnowledgeGraphNamedObjectType>();
      all_graph_types.AddRange(entities.Values);
      all_graph_types.AddRange(relationships.Values);
      all_graph_types.AddRange(provenance.Values);

      System.Diagnostics.Debug.WriteLine("\r\nGraph Types");

      int c = 0;
      foreach (var graph_type in all_graph_types)
      {
        var type_name = graph_type.GetName();
        var role = graph_type.GetRole().ToString();

        //equivalent to:
        //var fields = featClassDef.GetFields().Select(f => f.Name).ToList();
        //var field_names = string.Join(",", fields);
        var props = graph_type.GetProperties().Select(p => p.Name).ToList();
        var prop_names = string.Join(",", props);

        System.Diagnostics.Debug.WriteLine($"[{c++}]: " +
            $"{type_name}, {role}, {prop_names}");
      }
    }
  }
});
