How does the "mixin" code handle defining the target for the
AnnotationInstances it creates?
AFAIK it needs to look at two things, the ‘access’ attribute of the persistence unit and
the ‘access' attribute
of the entity node. Based on that it should create an AnnotationInstance with the
appropriate AnnotationTarget.
Once these pseudo annotation are created the processing of the mapping information is the
same as with actual
annotation defined on the entities (metadata-complete needs to be handled here as well in
a sense that if
a xml mapped entity is metadata-complete, existing AnnotationInstances based on actual
annotations must be removed).
That’s how it should work. However, this was Strong’s baby. Maybe he could shed some more
light on this.
Seems to me this code would have really no idea whether to choose the
field
or the getter as the target. Which is potentially problematic as we are
validating the "placement" of these annotations.
It does, based on the ‘access’ attribute (see above)
