Constructing generic objects [message #777098]

I used the sample editor to create some generic classes (after enabling "show generics") such Foo<T>. When I use the generated EMF editor to create a Foo object, I don't see any way to specify what T is. Is there any way to do that (or does type erasure render this moot)?

Thanks,

Mike

Mike,

No, there's no way to do this. There's no information available at
runtime that would represent it. The same is the case for Java, i.e,
you can call getClass, and perhaps determine it's java.util.List, but
not that it's java.util.List<java.lang.Integer>.
