[webbeans-dev] Re: CreationalContext.destroyDependents()

[Gavin King]

Oh no, I guess you can have the container handle this by wrapping Contextual:

  class ContextualWrapper<X> implements Contextual<X> {
	
	Contextual<X> contextual;
	DependentObjects dependentObjects;
	
	ContextualWrapper(DependentObjects dependentObjects) {
		this.dependentObjects = dependentObjects;
	}
	
	public X create(CreationalContext<X> cc) {
		return contextual.create(cc);
	}
	
	public void destroy(X instance) {
		contextual.destroy(instance);
		dependentObjects.destroy();
	}
		
  }

That works, right?
