Types

type Cond

type Cond struct {
	L sync.Locker
	// contains filtered or unexported fields
}

Cond 条件变量不保证顺序性，即signal只是通知wait去获取数据，wait拿到的数据是不是 signal当时给的数据，不能保证

func NewCond

func NewCond(l sync.Locker) *Cond

func (*Cond) Broadcast

func (c *Cond) Broadcast()

func (*Cond) BroadcastDo

func (c *Cond) BroadcastDo(do func() error)

func (*Cond) Signal

func (c *Cond) Signal()

func (*Cond) SignalDo

func (*Cond) WaitForDo
