Display a subtype feature layer

Display a composite layer of all the subtype values in a feature class.

Use case

This is useful for controlling labeling, visibility, and symbology of a given subtype as though they are distinct layers on the map.

How to use the sample

The sample loads with the sublayer visible on the map. Toggle its visibility by clicking the "Show sublayer " checkbox. Toggle between the sublayer's original renderer and an alternate renderer using the radio buttons. Click the "Set sublayer minimum scale" button to set the sublayer's minimum scale to the current map scale.

How it works

  1. Create a SubtypeFeatureLayer from a ServiceFeatureTable that defines a subtype, and add it to the ArcGISMap.
  2. Get a SubtypeSublayer from the subtype feature layer using its name.
  3. Enable the sublayer's labels and define them with getLabelDefinitions().
  4. Set the sublayer's visibility with setVisible().
  5. Change the sublayer's renderer/symbology with setRenderer().
  6. Update the sublayer's minimum scale value with setMinScale().
