Thread.eventLoop

Listens for events received by the current thread (the thread of the caller).

    
    
    
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
            Log(_D(), "thread1 eventMsg:", eventMsg)
            // Output: 2024-11-14 10:14:18 thread1 eventMsg: {"Seq":1,"Event":"thread","ThreadId":0,"Index":1,"Queue":0,"Nano":1731550458699947000}
        }
    })

    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(). It always listens for events of the caller's thread, regardless of which Thread object it is called on; for example, calling t1.eventLoop() in the main thread returns main-thread events.
