如何使用TaskPool在子线程调用对象成员函数

// Index.ets代码 
import taskpool from '@ohos.taskpool'; 
import { SendClass } from './SendClass'; 
 
let sendClass2 = new SendClass(); 
 
// 步骤1: 定义并发函数，内部调用同步方法 
@Concurrent 
function func(arr: Array<SendClass>): number { 
  let test = arr[0]; 
  let sum = test.GetValue() + 1; 
  return sum; 
} 
 
// 步骤2: 创建任务并执行 
function syncGet(): void { 
  let array1 = new Array<SendClass>(); 
  array1.push(sendClass2); 
  let task: taskpool.Task = new taskpool.Task(func, array1); 
  task.setCloneList(array1); 
  taskpool.execute(task).then((result: object) => { 
    console.log("testTag result:" + result); 
  }); 
} 
 
@Entry 
@Component 
struct Index { 
  @State message: string = 'Hello World'; 
 
  build() { 
    Row() { 
      Column() { 
        Text(this.message) 
          .fontSize(50) 
          .fontWeight(FontWeight.Bold) 
          .onClick(() => { 
            // 步骤3: 执行并发操作 
            syncGet(); 
          }) 
      } 
      .width('100%') 
    } 
    .height('100%') 
  } 
}
@Sendable 
export class SendClass { 
  value: number = 888; 
 
  GetValue(): number { 
    return this.value; 
  } 
 
  Print(): void { 
    console.log("value:" + this.value); 
  } 
}
