- Method Detail
  - apply
```
Response<?> apply(P parentResource,
                  I input)
           throws Exception
```
    Process the modification on the collection resource.
    The value of the returned response is automatically converted to JSON unless it is a BinaryResult.
    The returned response defines the status code that is returned to the client. For RestCollectionModifyViews this is usually 200 OK, but other 2XX or 3XX status codes are also possible (e.g. 201 Created if a resource was created, 202 Accepted if a background task was scheduled, 204 No Content if no content is returned, 302 Found for a redirect).
    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 - the collection resource on which the modification is done
    
    Returns:
    
    response to return to the client
    
    Throws:
    
    Exception - the implementation of the view failed. The exception will be logged and HTTP 500 Internal Server Error will be returned to the client.
