public AtraceCollector ()

public void onTestEnd (DeviceMetricData testData, 
                 currentTestCaseMetrics)

Callback when a test case is ended. This should be the time for clean up.

Parameters
`testData`	`DeviceMetricData`: the `DeviceMetricData` holding the data for the test case. Will be the same object as during `onTestStart(com.android.tradefed.device.metric.DeviceMetricData)`.
`currentTestCaseMetrics`	: the current map of metrics passed to `ERROR(/#testEnded(com.android.tradefed.result.TestDescription,Map))`.

public void onTestStart (DeviceMetricData testData)

Callback when a test case is started.

Parameters
`testData`	`DeviceMetricData`: the `DeviceMetricData` holding the data for the test case.

protected String fullLogPath ()

Returns
`String`

protected LogDataType getLogType ()

Returns
`LogDataType`

protected void startTracing (ITestDevice device)

Parameters

protected void stopTracing (ITestDevice device)

Parameters
`device`	`ITestDevice`
