BasePostProcessor

public abstract class BasePostProcessor
extends Object implements IPostProcessor

java.lang.Object
↳	com.android.tradefed.postprocessor.BasePostProcessor

Known direct subclasses

AggregatePostProcessor, AveragePostProcessor, StatsdGenericPostProcessor

AggregatePostProcessor	A metric aggregator that gives the min, max, mean, variance and standard deviation for numeric metrics collected during multiple-iteration test runs, treating them as doubles.
AveragePostProcessor	Implementation of post processor that calculate the average of the list of metrics.
StatsdGenericPostProcessor	A post processor that processes binary proto statsd reports into key-value pairs by expanding the report as a tree structure.

Known indirect subclasses

StatsdEventMetricPostProcessor

StatsdEventMetricPostProcessor A post processor that processes event metrics in statsd reports into key-value pairs, using the formatters specified on the processor.

The base IPostProcessor that every implementation should extend. Ensure that the post processing methods are called before the final result reporters.

TODO: expand to file post-processing too if needed.

Public constructors

BasePostProcessor

Public methods

init

public final ITestInvocationListener init (ITestInvocationListener listener)

Initialization step of the post processor. Ensured to be called before any of the tests callbacks.

Parameters
`listener`	`ITestInvocationListener`

Returns
`ITestInvocationListener`

invocationEnded

public final void invocationEnded (long elapsedTime)

Parameters
`elapsedTime`	`long`

invocationFailed

public final void invocationFailed (FailureDescription failure)

invocationFailed

public final void invocationFailed (Throwable cause)

Parameters
`cause`	`Throwable`

invocationStarted

public final void invocationStarted (IInvocationContext context)

Invocation Listeners for forwarding

Parameters
`context`	`IInvocationContext`

isDisabled

public final boolean isDisabled ()

Returns True if entire object disabled (skip both setup and teardown). False otherwise.

Returns
`boolean`

logAssociation

public final void logAssociation (String dataName, 
                LogFile logFile)

Updates the log-to-test assocation. If this method is called during a test, then the log belongs to the test; otherwise it will be a run log.

Parameters
`dataName`	`String`
`logFile`	`LogFile`

processAllTestMetricsAndLogs

public  processAllTestMetricsAndLogs (ListMultimap<String, MetricMeasurement.Metric> allTestMetrics, 
                 allTestLogs)

Implement this method to aggregate metrics and logs across all tests. Metrics coming out of this method will be reporter as run metrics. Only the newly generated metrics should be returned, and with unique key name (no collision with existing keys are allowed).

Parameters
`allTestMetrics`	`ListMultimap`: A HashMultimap storing the metrics from each test grouped by metric names.
`allTestLogs`	: A map storing each test's map of log files keyed by their data names, using the each test's `TestDescription` as keys.

Returns
	The set of newly generated metrics from all test metrics.

processRunMetricsAndLogs

public abstract  processRunMetricsAndLogs ( rawMetrics, 
                 runLogs)

Implement this method in order to generate a set of new metrics from the existing metrics and logs. Only the newly generated metrics should be returned, and with unique key name (no collision with existing keys are allowed).

Parameters
`rawMetrics`	: The set of raw metrics available for the run.
`runLogs`	: The set of log files for the test run.

Returns
	The set of newly generated metrics from the run metrics.

processTestMetricsAndLogs

public  processTestMetricsAndLogs (TestDescription testDescription, 
                 testMetrics, 
                 testLogs)

Implement this method to post process metrics and logs from each test. Only the newly generated metrics should be returned, and with unique key name (no collision with existing keys are allowed).

Parameters
`testDescription`	`TestDescription`: The TestDescription object describing the test.
`testMetrics`	: The set of metrics from the test.
