Extension: OSGi Focus Service

[jpasski]

ModelFocal

OSGi producer:

interface ModelFocal {
  EObject getFocus();
  void setFocus(EObject);
}

Use cases for model addition:

• Focus gotten when at the beginning of adding objects, to know where to add objects
• Focus set when at the end of adding objects, to inform others of where the new focus should be

  ModelFocalUpdateHandler

OSGi consumer:

interface ModelFocalUpdateHandler {
  void onUpdate(EObject);
}

Use cases for handler:

• Consumers onUpdates are called by ModelFocal.setFocus
