@ohos.distributedHardware.hardwareManager (分布式硬件管理)(系统接口)

分布式硬件管理模块提供控制分布式硬件的能力，包括暂停、恢复和停止被控端分布式硬件业务。

说明：

本模块首批接口从API version 11开始支持。后续版本的新增接口，采用上角标单独标记接口的起始版本。

本模块接口为系统接口。

导入模块

import hardwareManager from '@ohos.distributedHardware.hardwareManager';

HardwareDescriptor

表示分布式硬件的描述信息。

系统能力：SystemCapability.DistributedHardware.DistributedHardwareFWK

DistributedHardwareType

表示分布式硬件类型。

系统能力：SystemCapability.DistributedHardware.DistributedHardwareFWK

DistributedHardwareErrorCode

分布式硬件错误码的枚举。

系统能力：SystemCapability.DistributedHardware.DistributedHardwareFWK

hardwareManager.pauseDistributedHardware

pauseDistributedHardware(description: HardwareDescriptor): Promise<void>

暂停被控端分布式硬件业务。使用promise异步回调。

参数：

返回值：

错误码：

示例：

import hardwareManager from '@ohos.distributedHardware.hardwareManager';
import { BusinessError } from '@ohos.base';

try {
  let description: hardwareManager.HardwareDescriptor = {
    type: 1,
    srcNetworkId: '1111'
  };
  hardwareManager.pauseDistributedHardware(description).then(() => {
    console.log('pause distributed hardware successfully');
  }).catch((error: BusinessError) => {
    console.error('pause distributed hardware failed, cause:' + error);
  })
  console.log('pause distributed hardware successfully');
} catch (error) {
  console.error('pause distributed hardware failed:' + error);
}

hardwareManager.resumeDistributedHardware

resumeDistributedHardware(description: HardwareDescriptor): Promise<void>

恢复被控端分布式硬件业务。使用promise异步回调。

需要权限：ohos.permission.ACCESS_DISTRIBUTED_HARDWARE

系统能力：SystemCapability.DistributedHardware.DistributedHardwareFWK

参数：
