Cool :)
We will add jType to the Bean Validation RI Alpha2 (one release after
the first).

Okay, I've created the project here:

The method you're after is TypeUtils.isAssignable. I'm interested in
fleshing out this library in future, keeping the focus on pure type
operations. I'd like to implement full type inference and type
capturing in line with the JLS as I've had a requirement for this in
the past. Do let me know if you have any comments or suggestions.

all good.

Extra hands would be appreciated so I can't see a problem with
giving
you commit access. Copyright isn't an issue as I work for my own
company :)
I'll post the URL once it's up there. Likely to be after the
weekend
if that's alright?

That's fine, you can go host it on google-code under the ASL 2.
That way
we
can use it as a source level or jar level dependency.
It would be nice to get commit access so we can participate in
enhancing
the
support coverage.
Jboss.org might have some benefits as a forge but the .org team
is very
busy
at the moment, so creating a new project would be a bit low in
priority.
Google code is quite nice and clean.
BTW before dropping the code, make sure you have the copyright
rights (if
you developed that for a company, you might have to ask them).
Thanks!

ASL 2.0 is fine with me. I was thinking about hosting it
somewhere
like Google Code since there's a few open-source projects that
I've
seen which could benefit from it. Let me know, I can create a
project
and you can give it a spin.

Cool, that's already a nice start.
Let me see if I find something.
Would you be OK to contribute it under the ASL 2.0 license to us?

I haven't gone into supporting type variables, hence I don't
perform
type capturing or inference yet, although I would be
interested in
adding this. For an example of what is currently implemented,
the
following are from the tests:
Number <: Integer
Object <: Integer
List <: List<Integer>
Collection<Integer> <: List<Integer>
Collection<Integer> <: ArrayList<Integer>
List<Integer> !<: Set<Integer>
List<Number> !<: List<Integer>
List<?> <: List<Integer>
List<? extends Number> <: List<Number>
List<? extends Number> <: List<Integer>
List<? extends Number> !<: List<Object>
List<? super Number> <: List<Number>
List<? super Number> <: List<Object>
List<? super Number> !<: List<Integer>
List<Integer> <: IntegerArrayList
Let me know if you find any existing libraries since I use
this in my
other projects. If there's nothing out there then open-
sourcing this
would stop people from having to reinvent the wheel.

If I can't find an other alternative that would surely be of
help yes
:)
Do you know how much of the subtype rules you have implemented?
The one that sounded non trivial to me were around detecting
that
generic
are supertypes of others:
- containment and equivalence
- capture conversion
- intersection types
- management of bounds
(using the language of the JSL)

I've written a small utility library that provides methods
to work
with Types, specifically it contains such a method
isAssignable(Type
supertype, Type type) that should satisfy your requirements.
I've been considering open-sourcing it so would be happy to
do so if
you were interested?

Specifically a routine like
boolean isSuperType(Type super, Type, sub);
note Type, not Class<?>

Subtyping
I am looking for an ASL 2 / BSD implementation of the
subtyping
resolution
algorithm in Java.
I am thinking Harmony might have one.
Anybody knows?
