Assume a public interface I with two methods NotInS and M whereas NotInS
is calling M. An implementation i of I which implements NotInS and M as
well as a specialization s of i which only implements M. Finally a
constructor whose return-type is I returns a pointer to an instance of
s. Calling on this return-value NotInS will execute i.M() as the
following test shows. I would like it to call s.M(). How would I do
this in a goish way? Thanks for any help!
package main
import (
"fmt"
)
type I interface {
NotInS()
M()
}
type i struct{}
func (_i *i) NotInS() {
_i.M()
}
func (_i *i) M() {
fmt.Println("i")
}
type s struct{ *i }
func (_s *s) M() {
fmt.Println("s")
}
func newI() I {
return &s{&i{}}
}
func main() {
_i := newI()
_i.NotInS() // prints i instead of s
}
