关于HarmonyOS 鸿蒙Next TaskPool传参问题

给的例子可以执行，还有问题的话，得打开看看对imageData.readBuffer干了啥

import { taskpool } from '@kit.ArkTS';
import { emitter } from '@kit.BasicServicesKit';

@Concurrent
function fdFunc(data: ArrayBuffer, width: number, height: number) {
  let ua = new Uint8Array(data);
  ua[0] = 0;
  ua[1] = 0;
  ua[2] = 0;
  ua[3] = 0;
  console.log('[index] width =' + width + ', height = ' + height);
  for (let i = 0; i < ua.byteLength; i++) {
    console.log('[index] ' + ua[i]);
  }
  emitter.emit("fd", {
    data: {
      faceInfoList: ua
    }
  })
}

@Entry
@Component
struct Index {
  build() {
    Button('click').onClick(() => {
      let ua = new Uint8Array(4);
      ua[0] = 1;
      ua[1] = 1;
      ua[2] = 1;
      ua[3] = 1;
      let readBuffer = ua.buffer as ArrayBuffer;
      let task: taskpool.LongTask = new taskpool.LongTask(fdFunc, readBuffer,
        10, 20);
      task.setCloneList([readBuffer]);

      emitter.on("fd", (data: emitter.EventData) => {
        console.info("[index]eventdata = " + JSON.stringify(data));
        emitter.off("fd");
        taskpool.terminateTask(task);
        // 不调用setCloneList的话，使用转移模式，ua会变成undefined；调用setCloneList，对象转移使用拷贝模式，子线程和主线程都仍然能访问ua
        for (let i = 0; i < ua.byteLength; i++) {
          console.log('[index]2 ' + ua[i]);
        }
      })
      taskpool.execute(task);
    });
  }
}
