你可以依據偏好儲存及分類內容。
BluetoothConnectionLatencyCollector
public
class
BluetoothConnectionLatencyCollector
extends HostStatsdMetricCollector
收集器會將預先定義的 statsd 持續時間指標設定推送至裝置，並收集每個設定檔的藍牙連線時間。
摘要
欄位
BLUETOOTH_PROFILES_MAP
protected static final ImmutableMap<Integer, String> BLUETOOTH_PROFILES_MAP
對應項目會將藍牙設定檔編號與用於指標鍵的描述性名稱建立關聯。
公用建構函式
BluetoothConnectionLatencyCollector
public BluetoothConnectionLatencyCollector ()
受保護的方法
protected void processStatsReport (ITestDevice device,
InputStreamSource dataStream,
DeviceMetricData runData)
子類別可在必要時實作方法，以便處理 Statsd 指標報表。會針對特定裝置的評估指標報表呼叫
| 參數 |
|---|
device |
ITestDevice：測試 statsd 回報來源的裝置 |
dataStream |
InputStreamSource：統計資料報告做為輸入串流 |
runData |
DeviceMetricData：要儲存經過處理的指標的目的 |
