IExtensibleObject<T> Interface


Enable an object to participate in custom behavior, such as registering for events, or watching state transitions.

generic <typename T>
 where T : IExtensibleObject<T>public interface class IExtensibleObject
public interface IExtensibleObject<T> where T : IExtensibleObject<T>
type IExtensibleObject<'T (requires 'T :> IExtensibleObject<'T>)> = interface
Public Interface IExtensibleObject(Of T)

Type Parameters


The type of the extension class.



Implement IExtensibleObject<T> to enable aggregation of extensions.

For example, if you are implementing a TreeNode class and want to allow external code to add annotations and methods to some instances of TreeNode, you can have TreeNode implement IExtensibleObject<TreeNode>. This enables code that uses TreeNode to add objects that implement IExtensibleObject<TreeNode> to the Extensions collection.

There are four extensible objects in Windows Communication Foundation (WCF):

For a discussion about how to create extension to work with these objects, see Extensible Objects.



Gets a collection of extension objects for this extensible object.
