eventLoop

The eventLoop() function is used to listen for events received by the current thread.

    
    
    
eventLoop()

    
    
    
eventLoop(timeout)

Examples

Concurrently execute 3 threads, outputting the received event information; when a timeout occurs or it returns immediately, the output is null.

    javascript
    
    
function main() {
    var t1 = threading.Thread(function() {
        while (true) {
            var eventMsg = threading.currentThread().eventLoop()     // Block and wait
            // 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)   // Return immediately
            Log(_D(), "thread2 eventMsg:", eventMsg)
            Sleep(5000)
        }
    })

    var t3 = threading.Thread(function() {
        while (true) {
            var eventMsg = threading.currentThread().eventLoop(3000) // Set a 3-second timeout
            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()
}

Remarks

The processing mechanism of the eventLoop() function is consistent with that of the global function EventLoop().
