Improve the daoImplementationRequired implementation in EJB3Entity metafacade
-----------------------------------------------------------------------------
Key: EJB-106
URL: http://jira.andromda.org/browse/EJB-106
Project: EJB Cartridge
Type: Improvement
Environment: AndroMDA 3.3-SNAPSHOT + EJB3 cartridge
Reporter: Olivier THIERRY
Assigned to: Vance Karimi
Priority: Minor
Working on the patch to separate DAO and Transformer
(http://galaxy.andromda.org/jira/browse/EJB-105), I asked myself a question
about the way we decide if DAO implementation class has to be generated in
core/src/main/java or core/target/src. I have many DAO implementation classes
generated in core/src/main/java, but with no method to complete !
This choice is based upon daoImplementationRequired property of entity. In the
metafacade class, I saw this property is true in one of the the three following
cases :
1 - Entity has value objects references
2 - Entity has business operations, i.e. static methods
3 - Entity has query operations (methods checked as a query or having
<<FinderMethod>> stereotype).
I agree with the first two cases, but I don't understand the third one. For
what I understood, if a method is checked as a query or has the
<<FinderMethod>> stereotype, the query itself will be totally generated in
DAOBase class, so no need for the developer to implement it in a DAOImpl class.
So the first two methods should be enough to decide whether the developer will
have to write the DAO implementation.
After applying the patch about Transformer / DAO separations, it means there's
only one case when you need to generate DAO implementation class : when the
entity has business operations.
