ChangeInterceptorAttribute Class

Definition

The ChangeInterceptorAttribute on a method is used to process updates on the specified entity set name.

public ref class ChangeInterceptorAttribute sealed : Attribute
[System.AttributeUsage(System.AttributeTargets.Method, AllowMultiple=true, Inherited=true)]
public sealed class ChangeInterceptorAttribute : Attribute
[<System.AttributeUsage(System.AttributeTargets.Method, AllowMultiple=true, Inherited=true)>]
type ChangeInterceptorAttribute = class
    inherit Attribute
Public NotInheritable Class ChangeInterceptorAttribute

Examples

For more information, see the example in the QueryInterceptorAttribute topic.

Remarks

Resource-level change authorization and validation is implemented by methods annotated on the ChangeInterceptorAttribute. WCF Data Services provides the infrastructure required for service developers to write per-entity change processing rules and validation.

Entity-level access control and validation can be enforced through query interceptors. For more information, see QueryInterceptorAttribute.
