HarmonyOS 鸿蒙Next TaskPool使用方法

HarmonyOS 鸿蒙Next TaskPool使用方法

1. 类中方法无法使用 @Concurrent 提示 The @Concurrent decorator can decorate only common functions and async functions. 无法使用 taskpool

2。在测试类中无法使用 taskpool

it('lala', 0, () => {
    histogramStatistis(1);
});

function histogramStatistis(count: Number): void {
    let group: taskpool.TaskGroup = new taskpool.TaskGroup();
    group.addTask(imageProcessing, count);
    taskpool.execute(group, taskpool.Priority.HIGH).then((ret: ArrayBuffer[]) => {
        console.log(ret.toString());
    })
}

@Concurrent async function imageProcessing(data: String): Promise<String> {
    const result: String = await new Promise<String>((resolve) => {
        setTimeout(() => {
            console.log("data:" + data, "lala");
            resolve(data);
        }, 2000)
    })
    return result;
}

内容不打印，但是正常调用没问题
