LineEventSourceOptions Constructor
Initializes a new instance of the LineEventSourceOptions class.
Syntax
public LineEventSourceOptions()
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);
        }
