when I run the code snippet bellow, it raise a error
a.test undefined (type interface {} is interface with no methods)
It seem the type switch does not take effect.
package main
import (
"fmt"
)
type A struct {
a int
}
func(this *A) test(){
fmt.Println(this)
}
type B struct {
A
}
func main() {
var foo interface{}
foo = A{}
switch a := foo.(type){
case B, A:
a.test()
}
}
If I change it to
switch a := foo.(type){
case A:
a.test()
}
it's ok now.
