golang setting pointer slice with reflect
package main
import (
type X struct {
Name string
Values *[]Y
type Y struct {
Name string
func main() {
x := X{}
//t := reflect.TypeOf(x)
val := reflect.ValueOf(x)
vals := val.FieldByName("Values")
tY := vals.Type().Elem()//get non pointer - []Y
point := reflect.New(tY)
fmt.Printf("point: %#v\n", point)
elem := point.Elem()
elem.Set(reflect.MakeSlice(tY, 0, 0))
fmt.Printf("point: %#v\n", point)
newSlice := reflect.New(tY.Elem())//get Y
elem.Set(reflect.Append(elem, newSlice.Elem()))
fmt.Printf("Hello, playground %#v\n%#v\n", tY, point)
