Re: [hibernate-dev] overriding target through annotations
this would help on a related issue
http://opensource.atlassian.com/projects/hibernate/browse/HHH-2268 which
is about the problem of redundant methods in jdk5 when you have covariant
methods (e.g. Object clone() in Object and Customer clone() in Customer)
With respect to HHH-2268 we could also filter out the bridge methods (by
checking if they are volatile or not), but wouldn't that prevent users
from being able to annotate the covariant methods ?...or is the
annotations available on both methods...i guess it needs testing.

I'm looking at ANN-422
In HA, the target is usually inferred from the API (generics), and can
be overridden in all associations through targetEntity (
@ManyToOne(targetEntity...) )
currently, you cannot override the target for a component, nor you can
override it for a <map-key-many-to-many/>
Two solutions
1.
Define a @Target annotation that will work like the targetEntity for
association and also handle components (@Embedded)
Define a @MapKeyTarget to override the <map-key-many-to-many/> or
<map-key/> (composite-element) target
2.
Define a @Target annotation that will work like the targetEntity for
association and also handle components (@Embedded)
add a targetElement to @MapKey and @MapKeyManyToMany annotations
I don't like much 2 because it mixes physical concerns and logical ones,
but it reduce the amount of needed annotations
Note that I hope the future spec will hopefully handle all cases nicely
(ie add a targetElement in @Embedded), @MapKey should go to back the
drawing board from a spec POV so we can think of something clean from
the begining.
Any preference, or alternative solution?
