Class ILayerExtensionsProxy

java.lang.Object
  com.esri.arcgis.interop.Dispatch
      com.esri.arcgis.carto.ILayerExtensionsProxy

All Implemented Interfaces:

ILayerExtensions, Externalizable, Serializable

public class ILayerExtensionsProxy
extends com.esri.arcgis.interop.Dispatch
implements ILayerExtensions, Serializable

Provides access to the extensions of a layer.

Remarks

Use this interface to manage a layer's extensions. Extensions extend a layer's behavior.

There are several ESRI layer extensions. One set implements ILayerExtensionDraw. These coclasses store information that is used to display linearly referenced data layers. Another set of ESRI layer extensions implement IDataLayerExtension. These coclasses store information that is used to display 3D data layers in ArcScene and ArcGlobe. Another set implements IFeatureLayerSourcePageExtension. These coclasses control special dialogs for setting a feature layer's data source. Layer extensions need to implement IPersistStream to be persisted in the layer/map.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.
