Look up callback methods on listener superclasses
-------------------------------------------------
Key: CAY-950
URL: https://issues.apache.org/cayenne/browse/CAY-950
Project: Cayenne
Issue Type: Improvement
Components: Cayenne Core Library
Affects Versions: 3.0
Reporter: Andrus Adamchik
Assignee: Andrus Adamchik
Fix For: 3.0
This is another feature that expands Cayenne listener implementation compared
to JPA (the first one was CAY-949). To facilitate code reuse it should be nice
to be able to define callback methods in a listener superclass, so that
subclasses could simply override some behavior without declaring all callback
methods. In fact JPA does not prohibit this behavior. It just doesn't mention
anything about the superclass methods of a listener class.
Currently Cayenne throws when a declared callback method is not found. I am
going to add lookup for the method in question up the hierarchy.
