BluetoothConnectionLatencyCollector
public
class
BluetoothConnectionLatencyCollector
extends HostStatsdMetricCollector
收集器会将预定义的 StatsD 时长指标配置推送到设备，并收集每个配置文件的蓝牙连接时长。
摘要
字段
BLUETOOTH_PROFILES_MAP
protected static final ImmutableMap<Integer, String> BLUETOOTH_PROFILES_MAP
映射用于将蓝牙配置文件编号与用于指标键的描述性名称相关联。
公共构造函数
BluetoothConnectionLatencyCollector
public BluetoothConnectionLatencyCollector ()
受保护的方法
protected void processStatsReport (ITestDevice device,
InputStreamSource dataStream,
DeviceMetricData runData)
子类可以根据需要实现此方法来处理 Statsd 指标报告。系统会针对特定设备调用此接口来获取指标报告
| 参数 |
|---|
device |
ITestDevice：statsd 报告的来源测试设备 |
dataStream |
InputStreamSource：将统计信息报告作为输入流 |
runData |
DeviceMetricData：要存储已处理指标的目标位置 |
