How to cast reflect.Value to its type?

type Cat struct {      Age int }  cat := reflect.ValueOf(obj) fmt.Println(cat.Type()) // Cat  fmt.Println(Cat(cat).Age) // doesn't compile fmt.Println((cat.(Cat)).Age) // same 

Thanks!

Answer 1

concreteCat,_ := reflect.ValueOf(cat).Interface().(Cat) 

see http://golang.org/doc/articles/laws_of_reflection.html fox example

type MyInt int var x MyInt = 7 v := reflect.ValueOf(x) y := v.Interface().(float64) // y will have type float64. fmt.Println(y) 

Answer 2

Ok, I found it

reflect.Value has a function Interface() that converts it to interface{}
