Generic Cayenne POJO enhancer
-----------------------------
Key: CAY-682
URL: http://issues.apache.org/cayenne/browse/CAY-682
Project: Cayenne
Type: Task
Components: Cayenne Core Library
Versions: 3.0
Reporter: Andrus Adamchik
Assigned to: Andrus Adamchik
Fix For: 3.0
JPA implies POJO persistence, so to hook up pojos to Cayenne we need an
enhancer.
However it looks like the enhancer itself doesn't have to know anything about
JPA - it can be built on top of Cayenne. I prototyped an ASM-based enhancer [1]
that turns a POJO into a Persistent instance and also does property
interception. It is much cleaner and intuitive than our current CGLIB JPA
enhancer, and (again) - it does not depend on anything JPA.
The next steps I am going to take:
* move it to Cayenne core,
* create more tests
* switch JPA to the new enhancer
* add support for relationships interception
So we will support POJO's without JPA! (and without spending any extra time in
addition to what was planned for JPA work).
