    LineEventSourceOptions Constructor
    In This Topic
    Initializes a new instance of the LineEventSourceOptions class.
    Syntax
    public LineEventSourceOptions()
    Public Function New()
    Example
    Create a RouteEventSource via dynamic segmentation process for line events
    public void CreateLineEventSource(Geodatabase geodatabase, string routeFeatureClassName = "Roads", string eventTableName = "Accidents", string routeIdFieldName = "RID", string toMeasureFieldName = "toMeasure", string fromMeasureFieldName = "fromMeasure", string offsetFieldName = "Offset")
    {
        using (FeatureClass routesFeatureClass = geodatabase.OpenDataset<FeatureClass>(routeFeatureClassName))
        using (Table eventsTable = geodatabase.OpenDataset<Table>(eventTableName))
        {
            RouteInfo routeInfo = new RouteInfo(routesFeatureClass, routeIdFieldName);
            EventInfo eventInfo = new LineEventInfo(eventsTable, routeIdFieldName, fromMeasureFieldName, toMeasureFieldName, offsetFieldName);
            RouteEventSourceOptions routeEventSourceOptions = new LineEventSourceOptions() { IsPositiveOffsetOnRight = true };
    
            using (RouteEventSource routeEventSource = new RouteEventSource(routeInfo, eventInfo, routeEventSourceOptions))
            using (RouteEventSourceDefinition routeEventSourceDefinition = routeEventSource.GetDefinition())
            {
                // Locating errors 
                IReadOnlyList<RouteEventSourceError> errors = routeEventSource.GetErrors();
    
                // Route event source fields 
                IReadOnlyList<Field> routeEventSourceFields = routeEventSourceDefinition.GetFields();
    
                // Add RouteEventSource to the ArcGIS Pro map
                FeatureLayerCreationParams layerParams = new FeatureLayerCreationParams(routeEventSource)
                {
                    Name = "HighCrashAreas"
                };
    
                LayerFactory.Instance.CreateLayer<FeatureLayer>(layerParams, MapView.Active.Map);
            }
        }
    }
