LayerCacheType Enumeration

In This Topic

Layer cache type. Use with Layer.SetCacheOptions to control layer caching options.

Syntax

C#
Visual Basic (Declaration)

public enum LayerCacheType : System.Enum, System.IComparable, System.IConvertible, System.IFormattable

Public Enum LayerCacheType 
   Inherits System.Enum
   Implements System.IComparable, System.IConvertible, System.IFormattable

Members

Member	Description
MaxAge	Cache will be kept between sessions and cleared every Layer.MaxDisplayCacheAge minutes. Use SetDisplayCacheMaxAge to set the cache age. Not supported for layers that support feature caching (i.e. feature service layers).
None	Don't cache the layer locally. If the layer supports feature caching (i.e. is a feature service layer), then any existing cache is also cleared.
Permanent	Cache will be kept between sessions and invalidated when the data is updated. Not supported for layers that support feature caching (i.e. feature service layers).
Session	Cache will be cleared when the session ends.

Example

Set the layer cache

var featureLayer = MapView.Active.Map.GetLayersAsFlattenedList().OfType<FeatureLayer>().FirstOrDefault();
ArcGIS.Desktop.Framework.Threading.Tasks.QueuedTask.Run(() =>
{
  // change the layer cache type to maximum age
  //At 2.x - featureLayer.SetDisplayCacheType(ArcGIS.Core.CIM.DisplayCacheType.MaxAge);
  featureLayer.SetCacheOptions(LayerCacheType.MaxAge);
  // change from the default 5 min to 2 min
  featureLayer.SetDisplayCacheMaxAge(TimeSpan.FromMinutes(2));
});
