func NewCMap

func NewCMap() CMap

Creates a new concurrent map.

func (CMap) Add

func (m CMap) Add(key string, value int64)

func (m CMap) Count() int

Returns the number of elements within the map.

func (CMap) Exists

func (m CMap) Exists(key string) bool

Retrieves an element from map under given key.
