---

Base implementation of FilePullerDeviceMetricCollector that allows pulling the perfetto files from the device and collect the metrics from it. Also used for converting the raw trace file into perfetto metric file.

Summary

Nested classes
enum	PerfettoPullerMetricCollector.METRIC_FILE_FORMAT

Public constructors
PerfettoPullerMetricCollector()

Public methods
void	processMetricDirectory(String key, File metricDirectory, DeviceMetricData runData) Implementation of the method should allow to log the directory, parse it for metrics to be put in DeviceMetricData.
void	processMetricFile(String key, File metricFile, DeviceMetricData data) Process the perfetto trace file for the additional metrics and add it to final metrics.

Protected methods
File	retrieveFile(ITestDevice device, String remoteFilePath, int userId) Pull the file from the specified path in the device.

Public methods

processMetricDirectory

public void processMetricDirectory (String key, 
                File metricDirectory, 
                DeviceMetricData runData)

Implementation of the method should allow to log the directory, parse it for metrics to be put in DeviceMetricData.

Parameters
key	String: the option key associated to the directory that was pulled.
metricDirectory	File: the ERROR(/File) pulled from the device matching the option key.
runData	DeviceMetricData: the DeviceMetricData where metrics can be stored.

processMetricFile

public void processMetricFile (String key, 
                File metricFile, 
                DeviceMetricData data)

Process the perfetto trace file for the additional metrics and add it to final metrics. Decompress the perfetto file for processing if the compression was enabled.

Parameters
key	String: the option key associated to the file that was pulled from the device.
metricFile	File: the ERROR(/File) pulled from the device matching the option key.
data	DeviceMetricData: where metrics will be stored.

Protected methods

retrieveFile

protected File retrieveFile (ITestDevice device, 
                String remoteFilePath, 
                int userId)

Pull the file from the specified path in the device. Pull the compressed content of the perfetto file if the compress perfetto option is enabled.

Parameters
device	ITestDevice: which has the file.
remoteFilePath	String: location in the device.
userId	int: the user id to pull from

Returns
File	compressed or decompressed version of perfetto file based on mCompressPerfetto option is set or not.

Throws
DeviceNotAvailableException
