Functions ¶
func Lock ¶
func Lock(key string)
Lock locks the <key> with writing lock. If there's a write/reading lock the <key>, it will blocks until the lock is released.
func LockFunc ¶
func LockFunc(key string, f func())
LockFunc locks the <key> with writing lock and callback function <f>. If there's a write/reading lock the <key>, it will blocks until the lock is released.
It releases the lock after <f> is executed.
func RLock ¶
func RLock(key string)
RLock locks the <key> with reading lock. If there's a writing lock on <key>, it will blocks until the writing lock is released.
func RLockFunc ¶
func RLockFunc(key string, f func())
RLockFunc locks the <key> with reading lock and callback function <f>. If there's a writing lock the <key>, it will blocks until the lock is released.
It releases the lock after <f> is executed.
func TryLock ¶
TryLock tries locking the <key> with writing lock, it returns true if success, or if there's a write/reading lock the <key>, it returns false.
func TryLockFunc ¶
TryLockFunc locks the <key> with writing lock and callback function <f>. It returns true if success, or else if there's a write/reading lock the <key>, it return false.
It releases the lock after <f> is executed.
func TryRLock ¶
TryRLock tries locking the <key> with reading lock. It returns true if success, or if there's a writing lock on <key>, it returns false.
func TryRLockFunc ¶
TryRLockFunc locks the <key> with reading lock and callback function <f>. It returns true if success, or else if there's a writing lock the <key>, it returns false.
It releases the lock after <f> is executed.
Types ¶
type Locker ¶
type Locker struct {
// contains filtered or unexported fields
}
Locker is a memory based locker. Note that there's no cache expire mechanism for mutex in locker. You need remove certain mutex manually when you do not want use it anymore.
func New ¶
func New() *Locker
New creates and returns a new memory locker. A memory locker can lock/unlock with dynamic string key.
func (*Locker) Lock ¶
Lock locks the <key> with writing lock. If there's a write/reading lock the <key>, it will block until the lock is released.
func (*Locker) LockFunc ¶
LockFunc locks the <key> with writing lock and callback function <f>. If there's a write/reading lock the <key>, it will block until the lock is released.
It releases the lock after <f> is executed.
func (*Locker) RLock ¶
RLock locks the <key> with reading lock. If there's a writing lock on <key>, it will blocks until the writing lock is released.
func (*Locker) RLockFunc ¶
RLockFunc locks the <key> with reading lock and callback function <f>. If there's a writing lock the <key>, it will block until the lock is released.
It releases the lock after <f> is executed.
func (*Locker) TryLock ¶
TryLock tries locking the <key> with writing lock, it returns true if success, or it returns false if there's a writing/reading lock the <key>.
func (*Locker) TryLockFunc ¶
TryLockFunc locks the <key> with writing lock and callback function <f>. It returns true if success, or else if there's a write/reading lock the <key>, it return false.
It releases the lock after <f> is executed.
func (*Locker) TryRLock ¶
TryRLock tries locking the <key> with reading lock. It returns true if success, or if there's a writing lock on <key>, it returns false.
func (*Locker) TryRLockFunc ¶
TryRLockFunc locks the <key> with reading lock and callback function <f>. It returns true if success, or else if there's a writing lock the <key>, it returns false.
It releases the lock after <f> is executed.
