I think I'd need to see more of what you are trying to do - if you're
really mapping T's to H's then there has to be some place that the
mapping is maintained. You could create a custom module that registers
a Provider of HX for TX for all available T/Hs. But it would have to
scan (presumably) for T/s and H/s and that can be performance affecting.
The more automatic your discovery is, the more issues you can
potentially have with things sort of getting a bit inobvious, and
possibly negative for performance. Just be balanced and consider the
trade-offs.

yes multibinding is a way to go, is there a way to automatically
configure
it so I dont need to add all H* classes by hand?
thanks anyway.

You might want to look at MapBinder.

<http://stackoverflow.com/questions/13670060/guice-return-set-of-instances-with-custom-annotation#>
I have very simple scenario where class A registers instances for
types.
A.register(T1.class, new H1());
A.register(T2.class, new H2());
this is fairly simple configuration when done by hand but guice
injection
doesn't work when I create instances outside the guice framework.
I try to figure out how to create and configure A with all instance
with
custom annotation using guice. is guice even prepared for that?
I know that in java it is possible to use
javax.enterprise.inject.Instance to get all instances of type (and
optionally annotated with custom annotation) but I dont want to use
this if
possible.
thanks for any help
