}

M is the map type.

func New

func (r *Registry) Add(v, meta interface{}) *Value

Add adds the given interface and returns a new and unique box that identifies it.

func (*Registry) Each

func (r *Registry) Each(f func(interface{}, interface{}))

Each iterates over the map.

func (*Registry) EachValue

func (r *Registry) EachValue(f func(*Value, interface{}))

EachValue iterates over the map and gives the raw Value.

func (*Registry) IsEmpty

func (r *Registry) IsEmpty() bool
