Interface AttributeAware

All Superinterfaces:

Serializable

public interface AttributeAware
extends Serializable

This interface is just for internal use. It should ensure that refactorings don't lead to different method-names for the same purpose. Furthermore, it allows to easily find all artifacts which allow generic attributes.
