Would be correct the next way to implement the methods attached to an interface? (getKey, getData)

type reader interface {
    getKey(ver uint) string
    getData() string
}

type location struct {
    reader
    fileLocation string
    err os.Error
}

func (self *location) getKey(ver uint) string {...}

func (self *location) getData() string {...}

func NewReader(fileLocation string) *location {
    _location := new(location)
    _location.fileLocation = fileLocation
    return _location
}
