Here is a little snippet of code:
class Foo[A] {
def foo[B](param: SomeClass[B]) {
//
}
}
Now, inside foo, how do I:
1) verify if B is the same type as A?
2) verify if B is a subtype of A?
You need implicit type evidences,
<:<for subtype check and=:=for same type check. See the answers for this question.
