Inheritance:: VectorTileGraphicOrigin→GraphicOrigin

Since: ArcGIS Maps SDK for JavaScript 4.34

Provides information about the VectorTileLayer from which a graphic originates. Origin information maybe available when a graphic is returned from methods such as MapView.hitTest() method. You can access the graphic's origin through the graphic's Graphic.origin property.

The origin information contains the style layer's id and layer index within the vector tile style. Spatial information about the actual feature represented in the style layer is returned only if the style layer is a symbol layer. Otherwise, the graphic's geometry is null.

Example

// get screen point from view's click event
view.on("click", (event) => {
  // Search for all features only on included layers at the clicked location
  view.hitTest(event, {include: vectorTileLayer}).then((response) => {
    // if graphics are returned from vector tile layer, do something with results
    if (response.results.length){
      response.results.forEach((result, i) => {
        const layerId = result.graphic?.origin?.layerId;
        const styleLayer = vectorTileLayer.getStyleLayer(layerId);
        // update vector tile layer's style
      });
    }
  })
