Yeah thats what I thought, so I tried it...but it
doesn't work that way for more than one level, its a
little more complex.
For example: ClassifierFacadeLogic handles the getting
and creation of attributes and association ends
facades, EntityFacadeLogic extends this, so that means
you have the instance of ClassifierFacadeLogic within
EntityFacadeLogic as "super_" doing the calls for
getting attributes and getting association ends so
when the EntityFacadeLogic creates the instance of
ClassifierLogic for the "super_" variable we're able
to pass the context down in the createFacadeImpl
method like you talked about below which is then
passed to the ClassifierFacadeLogic so everything is
fine. But when you have an EJBEntityFacadeLogic which
extends EntityFacadeLogic the ClassifierFacadeLogic
still handles the calls to get attributes and
association ends so even if we pass the context down
to the EntityFacadeLogic during the createFacadeImpl
method the ClassifierFacadeLogic isn't being set by
the EJBEntityFacadeLogic context because we don't have
access to it (the EntityFacadeLogic class is the the
one that has access to it...so the context is always
set to "EntityFacade"). To fix this, I've changed
MetafacadeLogic.vsl to use a super${velocityCount} for
each superclass that the facade has....this way we're
able to pass the context (or whatever, to all the
subclasses...since inheritance doesn't work).
The performance is really bad with these new
metafacades (even before I added the change to
MetafacadeLogic.vsl)...its more noticable when you
have a class that has multiple super classes (i.e. the
EJB cartridge) I don't know if you've tried building
the cartridges with the new stuff....but the process
is much slower...and its REALLY noticable on the car
rental sample...what used to take 30 - 32 seconds on
my pc now takes 80! Maybe we need to see if we can
fix this?
