我们先来看这个函数修饰器的代码: modifier onlyByLocker() { address locker = Lockers.getCurrentLocker(); if (msg.sender...//需在这个回调函数里完成所有事情,包括支付等操作 result = ILockCallback(msg.sender).lockAcquired(data); if (Lockers.length...() == 1) {//只有一个locker的情况下,做清理操作 if (Lockers.nonzeroDeltaCount() !...= 0) revert CurrencyNotSettled(); Lockers.clear(); } else {//不止一个locker的情况下,移出顶部的locker...Lockers.pop(); } } 其中,Lockers 是封装了锁定操作的库合约,push() 函数会把当前调用者添加到锁定者队列里,具体实现用到了 EIP-1153 所引入的 tstore

变量存储当前锁对计数,Java实现如下: public class RedisWithReentrantLock { private ThreadLocal> lockers...jedis.del(key); } private Map currentLockers() { Map refs = lockers.get...= null) { return refs; } lockers.set(new HashMap()); return lockers.get(); }

2.PIN Lockers 另一种创新的勒索方式叫PIN Locker,这是一种可以更改设备PIN lock的勒索软件,解锁需要高达$500。
但是,使用驼峰形式命名测试方法的名字不太明显,一般建议用下划线_的形式:should_return_ticket_when_robot_save_bag_given_1_lockers_with_2_free_space
lockb i_cilock; /* tas to synchronize i_flag changes */ ushort i_rdlocks; /* count of non-exclusive lockers
Rights Lockers概念是一个实际的authenticatedauthorized playback system(经过身份验证的授权播放系统)。
