Functions

func Lock

func Lock(key string)

Lock 对key加锁，如果key已经存在锁，则会阻塞等待锁

func LockFunc

func LockFunc(key string, f func())

LockFunc 对key加锁，并且执行方法f，执行成功自动解锁

func RLock

func RLock(key string)

RLock 都key加读锁，如果key已存在写锁，则会阻塞等待

func RLockFunc

func RLockFunc(key string, f func())

RLockFunc 对key加读锁执行方法f，执行成功自动解锁

func RUnlock

func RUnlock(key string)

RUnlock 对key进行读解锁

func Remove

func Remove(key string)

Remove 移除在key身上的锁

func TryLock

func TryLock(key string) bool

TryLock 尝试对key加锁，如果加锁成功返回true，加锁失败返回false

func TryLockFunc

func TryLockFunc(key string, f func()) bool

TryLockFunc 尝试对key加锁，如果加锁成功则执行方法f，执行成功返回true，执行失败返回false

func TryRLock

func TryRLock(key string) bool

TryRLock 尝试对key加读锁，如果加锁成功返回true，失败返回false

func TryRLockFunc

func TryRLockFunc(key string, f func()) bool

TryRLockFunc 尝试对key加读锁，如果加锁成功则执行方法f，执行成功返回true，加锁失败或执行失败都返回false

func Unlock

func Unlock(key string)

Unlock 对key解锁

Types

type Locker

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

Locker 内存锁，底层使用map实现

func New

func New() *Locker

func (*Locker) Clear

func (that *Locker) Clear()

Clear 清空内存锁中的所有锁

func (*Locker) Lock

func (that *Locker) Lock(key string)

Lock 对该key增加写锁

func (*Locker) LockFunc

func (that *Locker) LockFunc(key string, f func())

LockFunc 对指定的key加锁，并执行方法

func (*Locker) RLock

func (that *Locker) RLock(key string)

RLock 对该key增加读锁

func (*Locker) RLockFunc

func (that *Locker) RLockFunc(key string, f func())

RLockFunc 对指定的key加读锁，并执行方法

func (*Locker) RUnlock

func (that *Locker) RUnlock(key string)

RUnlock 对指定的key解锁

func (*Locker) Remove

func (that *Locker) Remove(key string)

Remove 移除指定key的锁

func (*Locker) TryLock

func (that *Locker) TryLock(key string) bool

TryLock 尝试对该key增加写锁，加锁成功返回true，加锁失败返回false

func (*Locker) TryLockFunc

func (that *Locker) TryLockFunc(key string, f func()) bool

TryLockFunc 尝试对指定的key加锁，加锁成功则执行f方法，如果加锁并执行成功则返回true，否则返回false

func (*Locker) TryRLock

func (that *Locker) TryRLock(key string) bool
