LogcatTimingMetricCollector

public class LogcatTimingMetricCollector
extends BaseDeviceMetricCollector

java.lang.Object
↳	com.android.tradefed.device.metric.BaseDeviceMetricCollector
	↳	com.android.tradefed.device.metric.LogcatTimingMetricCollector

A metric collector that collects timing information (e.g. user switch time) from logcat during one or multiple repeated tests by using given regex patterns to parse start and end signals of an event from logcat lines.

Public methods

onTestEnd

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))`.

onTestFail

public void onTestFail (DeviceMetricData testData, 
                TestDescription test)

Callback when a test case fails.

Parameters
`testData`	`DeviceMetricData`: the `DeviceMetricData` holding the data for the test case.
`test`	`TestDescription`: the `TestDescription` of the test case in progress.

onTestRunEnd

public void onTestRunEnd (DeviceMetricData testData, 
                 currentTestCaseMetrics)

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

Parameters
`testData`	`DeviceMetricData`: the `DeviceMetricData` holding the data for the run. Will be the same object as during `onTestRunStart(com.android.tradefed.device.metric.DeviceMetricData)`.
`currentTestCaseMetrics`	: the current map of metrics passed to `ERROR(/#testRunEnded(long,Map))`.

onTestRunStart

public void onTestRunStart (DeviceMetricData testData)

Callback when a test run is started.

Parameters
`testData`	`DeviceMetricData`: the `DeviceMetricData` holding the data for the run.

Throws
`DeviceNotAvailableException`

onTestStart

public void onTestStart (DeviceMetricData testData)

Callback when a test case is started.

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

Throws
`DeviceNotAvailableException`
