监听当前线程接收到的事件。

    
    
    
eventLoop()

    
    
    
eventLoop(timeout)

示例

并发执行 3 个线程，输出接收到的事件信息；当超时或立即返回时，输出为空值。

    javascript
    
    
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()
}

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