    public interface RestCollectionDeleteMissingView<P extends RestResource,​C extends RestResource,​I>
    extends RestCollectionView<P,​C,​I>
    RestView that supports accepting input and deleting a resource that is missing.

    The RestDeleteMissingView solely exists to support a special case for creating a change edit by deleting a path in the non-existing change edit. This interface should not be used for new REST API's.

    The input must be supplied as JSON as the body of the HTTP request. Delete views can be invoked by the HTTP method DELETE.

    The RestDeleteMissingView is only invoked when the parse method of the RestCollection throws ResourceNotFoundException, and hence the resource doesn't exist yet.

    • Method Detail

      • apply

        Response<?> apply​(P parentResource,
                          IdString id,
                          I input)
                   throws Exception
        Process the view operation by deleting the resource.

        The returned response defines the status code that is returned to the client. For RestCollectionDeleteMissingViews this is usually 204 No Content because a resource is deleted, but other 2XX or 3XX status codes are also possible (e.g. 200 OK, 302 Found for a redirect).

        The returned response usually does not have any value (status code 204 No Content). If a value in the returned response is set it is automatically converted to JSON unless it is a BinaryResult.

        Throwing a subclass of RestApiException results in a 4XX response to the client. For any other exception the client will get a 500 Internal Server Error response.

        Parameters:
        parentResource - parent resource of the resource that should be deleted
        id - the ID of the child resource that should be deleted
        input - input after parsing from request
        Returns:
        response to return to the client
        Throws:
        RestApiException - if the resource creation is rejected
        Exception - the implementation of the view failed. The exception will be logged and HTTP 500 Internal Server Error will be returned to the client.
