Re: [emf-dev] EMF interface instance access pattern

Hello,

Hi,



In EMF runtime and generated code there is a "interface instance access" pattern like:

  public interface Registry
  {
    public static final Registry INSTANCE = new RegistryImpl();
  }

It is good and stable. It works perfect.
However, it may look "too static" for OSGi-based approach where interface should not reference its implementation.

How would you implement it today for OSGi-oriented architecture executed by 1.8+ Java?


You might be interested in this presentation [1] from Mikael Barbero (presented at EclipseCon 2012), which tried to imagine what a more modern/dynamic/OSGi-compatible version of EMF could look like if backward compatibility was not an issue (it is). It tackled this particular issue, among others.
