Including internal interface

Ruby JRuby
1

Supposing I have a java class and internally has an interface:

package test;

public class Foo
{
public interface Bar
{
double f (double x);
}
}

In JRuby, if I have the following:

class Impl
include Java::test.Foo.Bar

def f (x)
x*x
end
end

Does not find internal interface Bar. Trying with the correct java
mangling:

include Java::test.Foo$Bar

does not work either.

I would prefer not to require that the interface be at the toplevel
(i.e. not internal). How do I include it?

Thanks

Try include Java::test.Foo::Bar. Inner classes are treated like
module/class-scoped constants, which are accessed using ::.
