Lock

Lock()函数用于创建线程锁对象。

Lock()函数返回一个线程锁对象。

ThreadLock对象

Lock()

function consumer(productionQuantity, dict, lock) {
    for (var i = 0; i < productionQuantity; i++) {
        lock.acquire()
        var count = dict.get("count")        
        Log("consumer:", count)
        Sleep(1000)
        lock.release()
    }
}

function producer(productionQuantity, dict, lock) {
    for (var i = 0; i < productionQuantity; i++) {
        lock.acquire()
        dict.set("count", i)
        Log("producer:", i)
        Sleep(1000)
        lock.release()
    }
}

function main() {
    var dict = threading.Dict()
    dict.set("count", -1)
    var lock = threading.Lock()
    var productionQuantity = 10
    var producerThread = threading.Thread(producer, productionQuantity, dict, lock)
    var consumerThread = threading.Thread(consumer, productionQuantity, dict, lock)

    consumerThread.join()
    producerThread.join()
}

两个并发线程访问公共资源。

支持回测系统、实盘环境。
