Method UpdateObject

stack.go:234–241

UpdateObject is a helper function for Update that accepts any value type, which is then encoded into a byte slice using encoding/gob. Objects containing pointers with zero values will decode to nil when using this function. This is due to how the encoding/gob package works. Because of this, you sho

(id uint64, newValue interface{})

// package works. Because of this, you should only use this function
// to encode simple types.
func (s *Stack) UpdateObject(id uint64, newValue interface{}) (*Item, error) {
	var buffer bytes.Buffer
	enc := gob.NewEncoder(&buffer)
	if err := enc.Encode(newValue); err != nil {
		return nil, err
	}
	return s.Update(id, buffer.Bytes())
}
