    public final class ArcGISMapImageSublayer
extends ArcGISSublayer
    An ArcGIS map image sublayer.

    ArcGISMapImageLayer displays maps from an ArcGIS map server. Each layer in the underlying map service is represented by an ArcGISSublayer. You can control the visibility and symbols of sublayers and filter data with layer definition expressions.

    You can get a list of ArcGISMapImageSublayer objects from an ArcGISMapImageLayer by using ArcGISMapImageLayer.getSublayers(). You can also create a new sublayer from ArcGISMapImageSublayer(int).

    The code below shows how to get ArcGISMapImageSublayer objects from an ArcGISMapImageLayer and how to change a property of a sublayer after loading. 

     String mapServiceUSA = "http://sampleserver6.arcgisonline.com/arcgis/rest/services/USA/MapServer";
 final  ArcGISMapImageLayer mapImageLayer = new ArcGISMapImageLayer(mapServiceUSA);

 mapImageLayer.addDoneLoadingListener(() -> {
   if (mapImageLayer.getLoadStatus() == LoadStatus.LOADED) {
     ListenableList<ArcGISSublayer>  sublayerList = mapImageLayer.getSublayers();
     ArcGISMapImageSublayer mapImageSublayer = (ArcGISMapImageSublayer) sublayerList.get(0);
     mapImageSublayer.setName("New Name");
   }
 });
 mapImageLayer.loadAsync();
    Setting properties on a ArcGISMapImageSublayer before the ArcGISMapImageLayer is loaded will not overwrite those properties.

      • ArcGISMapImageSublayer

        public ArcGISMapImageSublayer​(int id)
        Creates a new ArcGISMapImageSublayer with the given ID. The ID should be zero or greater.
        Parameters:
        id - the ID of the new sub layer, should be zero or greater
        Throws:
        IllegalArgumentException - if id is less than zero

      • ArcGISMapImageSublayer

        public ArcGISMapImageSublayer​(int id,
                              SublayerSource sublayerSource)
        Creates a new ArcGISMapImageSublayer with the given ID and sublayer source. The ID should be zero or greater and the sublayer source cannot be null. For sublayer sources other than rasters, a Renderer must be set using setRenderer(Renderer).
        Parameters:
        id - the ID of the new sub layer, should be zero or greater
        sublayerSource - the source of the new sublayer
        Throws:
        IllegalArgumentException - if id is less than zero
        IllegalArgumentException - if sublayer source is null
