IExtension Interface (ArcObjects .NET 10.6 SDK)
|
This document is archived and information here might be outdated. Recommended version. |
Provides access to members that define an extension.
IExtension is implemented by developers of custom extensions. You do not normally use this interface from client code, other than to get the name of the extension.
Any extension that is registered with an application is automatically loaded and unloaded by the application; the end user does nothing to load or unload. For example, an extension that has been added to the ESRI Mx Extensions category will be started when ArcMap is started and will be shutdown when ArcMap is shutdown.
Use the IExtension interface to query the properties of an extension or to create your own extension.
When you are creating a new extension, you need to implement the IExtension interface in your class code. This interface allows you to set the name of the extension and specify what action takes place when the extension is started or shutdown.
| Name | Description | |

Name | The name of the extension. |
 |
Shutdown | Shuts down the extension. |
