Types

type Locker

type Locker struct {
	// contains filtered or unexported fields
}

Locker 写锁对象

func NewLocker

func NewLocker(logger glog.ILogger) *Locker

NewLocker 创建新的锁对象

func (*Locker) Lock

func (l *Locker) Lock(timeout int) (successful bool, prevStack string, currStack string)

Lock 尝试加锁，如果在指定的时间内失败，则会返回失败；否则返回成功 timeout:指定的毫秒数,timeout<=0则将会死等 返回值： 成功或失败 如果失败，返回上一次成功加锁时的堆栈信息 如果失败，返回当前的堆栈信息

func (*Locker) Unlock

func (l *Locker) Unlock()

Unlock 解锁

func (*Locker) WaitLock

func (l *Locker) WaitLock()

WaitLock 锁定（死等方式）

type RWLocker

type RWLocker struct {
	// contains filtered or unexported fields
}
