HarmonyOS Sendable装饰的对象怎么获取

参考如下demo，通过参数传递

// SendableTest.ets

@Sendable
export class Test {
  num: number = 10;
}


// Index.ets

import taskpool from '@ohos.taskpool';
import { Test } from './SendableTest';


@Concurrent
async function testFunc(test: Test): Promise<void> {
  let tmp = new Test();
  tmp.num = 1;
  test.num = tmp.num;
}

async function start(): Promise<taskpool.Task> {
  let test = new Test();
  test.num = 101;
  console.info("taskpoolTest:res1 is:" + test.num);
  let currTask = new taskpool.Task(testFunc, test);
  await taskpool.execute(currTask, taskpool.Priority.MEDIUM).then(() => {
    console.info("taskpoolTest:res2 is:" + test.num);
  }) as boolean
  return currTask;
}

@Entry
@Component
struct Index {
  @State message: string = 'Hello World';

  build() {
    Row() {
      Column() {
        Text(this.message)
          .fontSize(50)
          .fontWeight(FontWeight.Bold)
          .onClick(() => {
            start();
          })
      }
      .width('100%')
    }
    .height('100%')
  }
}
