package encoding/gob
DecodeValue reads the next value from the input stream. If v(1st parameter) is the zero reflect.Value (v.Kind() == Invalid), DecodeValue discards the value. Otherwise, it stores the value into v. In that case, v must represent a non-nil pointer to data or be an assignable reflect.Value (v.CanSet()) If the input is at EOF, DecodeValue returns io.EOF and does not modify e.
Golang encoding/gob.Decoder.DecodeValue() function usage example
func (ed *encDec) decode(value reflect.Value) error {
ed.decLock.Lock()
err := ed.dec.DecodeValue(value) // <--- here
if err != nil {
return err
}
ed.decLock.Unlock()
return err
}
