GetType returns a registered reflect.Type specified by name or an error.

func (*Registry) GetValue

func (r *Registry) GetValue(name string) (reflect.Value, error)

GetValue returns a new reflect.Value of reflect.Type registered under specified name or an error.

func (*Registry) Register

func (r *Registry) Register(v interface{}) error

Register registers a reflect.Type of value specified by v under its' reflect.Type name or returns an error.

func (*Registry) RegisterNamed

func (r *Registry) RegisterNamed(name string, v interface{}) error
