Abstract objEntities
--------------------
Key: CAY-794
URL: https://issues.apache.org/cayenne/browse/CAY-794
Project: Cayenne
Issue Type: New Feature
Affects Versions: 3.0
Reporter: Ari Maniatis
Assignee: Ari Maniatis
Fix For: 3.0
Implement the possibility for an objEntity to be abstract. These means that the
entity class generated by the template will be abstract.
1. Add atttribute isAbstract within <obj-entity ...> in the Cayenne data map.
2. Add checkbox to the modeler "[ ] abstract class"
3. void setIsAbstract(boolean) and boolean getIsAbstract() added to ObjEntity.
3. change template generation to add 'abstract' keyword
Other changes (such as throwing runtime exception when querying abstract entity
with no concrete subclasses) could probably wait until later since they need to
be implemented as part of inheritance.
