In below code, in order to show the expected type, I have to create a new object and call reflect.TypeOf
on it.
package main
import (
"fmt"
"reflect"
)
type X struct {
name string
}
func check(something interface{}) {
if _, ok := something.(*X); !ok {
fmt.Printf("Expecting type %v, got %v\n",
reflect.TypeOf(X{}), reflect.TypeOf(something))
}
}
func main()
check(struct{}{})
}
Perhaps that object creation is not an overhead, but I still curious to know a better way. Are there something like X.getName()
or X.getSimpleName()
in java?
