Template method in template class definition outside class

I want to have a template class with a template method inside and also define that method outside the class. I tried looking around for an answer, but couldn't find one.

For example:

template<typename A> class Type {
private:
    A value;
public:
    template<typename B> A Method(B value) {
        // some code here, it's not important for the sake of this example
    }
}

How would I move the definition of method Method to be outside the class body? Thanks in advance.
