eventLoop

eventLoop()函数用于监听线程收到的事件。

eventLoop()函数返回当前线程收到的事件信息，查看事件信息结构。

object、空值

eventLoop() eventLoop(timeout)

参数timeout为超时设置，单位为毫秒。参数timeout如果设置为0则等待有事件发生才返回，如果大于0就是设置事件等待超时，小于0立即返回最近事件。

timeout false number

function main() {
    var t1 = threading.Thread(function() {
        while (true) {
            var eventMsg = threading.currentThread().eventLoop()     // 阻塞等待
            // 2024-11-14 10:14:18 thread1 eventMsg: {"Seq":1,"Event":"thread","ThreadId":0,"Index":1,"Queue":0,"Nano":1731550458699947000}
            Log(_D(), "thread1 eventMsg:", eventMsg)
        }
    })

    var t2 = threading.Thread(function() {
        while (true) {
            var eventMsg = threading.currentThread().eventLoop(-1)   // 立即返回
            Log(_D(), "thread2 eventMsg:", eventMsg)
            Sleep(5000)
        }
    })

    var t3 = threading.Thread(function() {
        while (true) {
            var eventMsg = threading.currentThread().eventLoop(3000) // 设置3秒超时
            Log(_D(), "thread3 eventMsg:", eventMsg)
        }
    })

    t1.postMessage("Hello ", t1.name())
    t2.postMessage("Hello ", t2.name())
    t3.postMessage("Hello ", t3.name())
    t1.join()
    t2.join()
    t3.join()
}

并发执行3个线程，输出接收到的事件信息，超时或者立即返回时输出的是空值。

eventLoop()函数的处理机制与全局函数EventLoop()一致。
