Get pointer to value using reflection

Question

I have a function that iterates through all fields of an interface passed as parameter. In order to achieve this is I am using reflection. The issue is that I do not know ho

Answer 1

Passing reflect.Value instead of interface{} seems to fix the problem, however I don't know why valueField.Interface() doesn't work.

Working example : http://play.golang.org/p/nleA2YWMj8

func InspectStructV(val reflect.Value) {
    if val.Kind() == reflect.Interface && !val.IsNil() {
        elm := val.Elem()
        if elm.Kind() == reflect.Ptr && !elm.IsNil() && elm.Elem().Kind() == reflect.Ptr {
            val = elm
        }
    }
    if val.Kind() == reflect.Ptr {
        val = val.Elem()
    }

    for i := 0; i < val.NumField(); i++ {
        valueField := val.Field(i)
        typeField := val.Type().Field(i)
        address := "not-addressable"

        if valueField.Kind() == reflect.Interface && !valueField.IsNil() {
            elm := valueField.Elem()
            if elm.Kind() == reflect.Ptr && !elm.IsNil() && elm.Elem().Kind() == reflect.Ptr {
                valueField = elm
            }
        }

        if valueField.Kind() == reflect.Ptr {
            valueField = valueField.Elem()

        }
        if valueField.CanAddr() {
            address = fmt.Sprintf("0x%X", valueField.Addr().Pointer())
        }

        fmt.Printf("Field Name: %s,\t Field Value: %v,\t Address: %v\t, Field type: %v\t, Field kind: %v\n", typeField.Name,
            valueField.Interface(), address, typeField.Type, valueField.Kind())

        if valueField.Kind() == reflect.Struct {
            InspectStructV(valueField)
        }
    }
}

func InspectStruct(v interface{}) {
    InspectStructV(reflect.ValueOf(v))
}
