鸿蒙编程江湖：ArkTS开发综合案例与最佳实践 原创

import { TaskPool, asyncLock, deserialize, serialize } from '@ArkTS/system';
import { UIComponent, Event } from '@ArkTS/ui';
class DataProcessor {
  // 处理数据的逻辑
}

    super();
    this.dataProcessor = new DataProcessor();
  }
  @Event
  loadData() {
    TaskPool.dispatch(async () => {
      const data = await this.fetchData();
      const processedData = await this.processData(data);
      this.updateUI(processedData);
    });
  }
  private async fetchData(): Promise<string> {
    // 异步获取数据
  }
  private async processData(data: string): Promise<any> {
    // 使用异步锁处理数据
    return asyncLock.lock(async () => {
      const deserializedData = deserialize(data);
      const result = this.dataProcessor.process(deserializedData);
      return serialize(result);
    });
