New returns a new MgoStorage

func (*MgoStorage) Delete

func (self *MgoStorage) Delete(key string)

func (*MgoStorage) Get

func (self *MgoStorage) Get(key string) (resp []byte, ok bool)

func (*MgoStorage) Indexes

func (self *MgoStorage) Indexes()

func (*MgoStorage) Set

func (self *MgoStorage) Set(key string, content []byte)
