Overview

Package gmutex inherits and extends sync.Mutex and sync.RWMutex with more futures.

Note that, it is refracted using stdlib mutex of package sync from GoXrc version v2.5.2.

Types

type Mutex

type Mutex struct {
	sync.Mutex
}

Mutex is a high level Mutex, which implements more rich features for mutex.

func (*Mutex) LockFunc

func (m *Mutex) LockFunc(f func())

LockFunc locks the mutex for writing with given callback function `f`. If there's a write/reading lock the mutex, it will block until the lock is released.

It releases the lock after `f` is executed.

func (*Mutex) TryLockFunc

func (m *Mutex) TryLockFunc(f func()) (result bool)

TryLockFunc tries locking the mutex for writing with given callback function `f`. it returns true immediately if success, or if there's a write/reading lock on the mutex, it returns false immediately.

It releases the lock after `f` is executed.

type RWMutex

type RWMutex struct {
	sync.RWMutex
}

RWMutex is a high level RWMutex, which implements more rich features for mutex.

func New

func New() *RWMutex

New creates and returns a new mutex. Deprecated: use Mutex or RWMutex instead.

func (*RWMutex) LockFunc

func (m *RWMutex) LockFunc(f func())

LockFunc locks the mutex for writing with given callback function `f`. If there's a write/reading lock the mutex, it will block until the lock is released.

It releases the lock after `f` is executed.

func (*RWMutex) RLockFunc

func (m *RWMutex) RLockFunc(f func())

RLockFunc locks the mutex for reading with given callback function `f`. If there's a writing lock the mutex, it will block until the lock is released.

It releases the lock after `f` is executed.

func (*RWMutex) TryLockFunc

func (m *RWMutex) TryLockFunc(f func()) (result bool)

TryLockFunc tries locking the mutex for writing with given callback function `f`. it returns true immediately if success, or if there's a write/reading lock on the mutex, it returns false immediately.

It releases the lock after `f` is executed.

func (*RWMutex) TryRLockFunc

func (m *RWMutex) TryRLockFunc(f func()) (result bool)

TryRLockFunc tries locking the mutex for reading with given callback function `f`. It returns true immediately if success, or if there's a writing lock on the mutex, it returns false immediately.

It releases the lock after `f` is executed.
