        public StampedLockExecutor()
        构造函数

      • StampedLockExecutor

        public StampedLockExecutor​(StampedLock stampedLock)
        自定义锁
        Parameters:

    • Method Detail

      • lock

        public void lock​(Runnable action)
        Description copied from interface: LockExecutor
        执行带锁的操作（使用默认锁，对于读写锁而言是写锁）
        Specified by:
        lock in interface LockExecutor
        Parameters:
        action - 范围内进行锁操作

      • lock

        public <V> V lock​(Supplier<V> action)
        Description copied from interface: LockExecutor
        执行带锁的操作并返回结果（使用默认锁，对于读写锁而言是写锁）
        Specified by:
        lock in interface LockExecutor
        Type Parameters:
        V - 返回值类型
        Parameters:
        action - 范围内进行锁操作
        Returns:
        V 执行结果

      • readLock

        public void readLock​(Runnable action)
        Description copied from interface: LockExecutor
        读写锁特有方法，默认抛出 UnsupportedOperationException
        Specified by:
        readLock in interface LockExecutor
        Parameters:
        action - 范围内进行锁操作

      • readLock

        public <V> V readLock​(Supplier<V> action)
        Description copied from interface: LockExecutor
        读写锁特有方法，默认抛出 UnsupportedOperationException
        可自定义返回值
        避免在循环中使用拉姆达表达式在用此锁会降低效率
