[jira] [Commented] (PYLUCENE-53) JCC Default implementations from Interfaces not exposed

["Petrus Hyvönen (Jira)" <ji...@apache.org>]

Petrus Hyvönen commented on PYLUCENE-53:
----------------------------------------

Hi Andi,

Hope all well. Just wanted to check with you if you did spend any more thinking on this.. I almost understand what you write but way too complex for me to enter. I guess a generic way to solve this would be the best. Otherwise would there be a way basically to check the interfaces for default implementations and then refer on the "Cat" class up to "Being"? But it is likely some caveats on that..

I guess this is also related to the need of sometimes casting objects to "visualize" the right interface?

Regards

/P

> Hi,
> This may be related to PYLUCENE-27 but not sure.
> Default implementations of methods in an interface does not seem to be exposed currently.
> For example:
> The interface:
> interface Being {
>  public void printName();
>  default int getFeets()
>  {
>  return 4;
>  }
> }
> Implemented in the class:
> public class Cat extends Feline implements Being {
>  public void printName() {
>  System.out.println("Cat");
>  }
>  public int getJavaFeets()
>  {
>  return this.getFeets();
>  }
> }
> When wrapped in Python, the getJavaFeets is exposed to the Python side, but not the getFeets method.
