Interfaces
| Interfaces | Description |
|---|---|
| IDocumentVersionSupportGEN (esriSystem) | Provides access to extend the IObjectStream interface with methods to hande saving objects that did not exist in previous versions of the software. |
| IEditInteraction | Provides access to methods declaring how graphic attributes interact with a representation tool. |
| IGraphicAttributes | Provides access to members that control the graphic attributes. |
| IGraphicAttributes2 | Provides access to members that control the graphic attributes. |
| IMarkerPlacement | Provides access to members that control the marker placement. |
| IPersist | Defines the single method GetClassID, which is designed to supply the CLSID of an object that can be stored persistently in the system. IPersist is the base interface for three other interfaces: IPersistStorage, IPersistStream, and IPersistFile. |
| IPersistStream (esriSystem) |
