Class AppWakeupMetrics

java.lang.Object

com.facebook.battery.metrics.api.SystemMetrics<AppWakeupMetrics>

com.facebook.battery.metrics.appwakeup.AppWakeupMetrics

All Implemented Interfaces:

java.io.Serializable

public class AppWakeupMetrics
extends SystemMetrics<AppWakeupMetrics>

This class contains the metrics to measure the usage of different background scheduling mechanisms like Alarms, Jobschedulers, GCMNetworkManager. This is not an exhaustive list and we can add more reasons in the future. We record the number of times and the total duration of execution for each of these wakeups.

Method Detail

set

public AppWakeupMetrics set(AppWakeupMetrics metrics)

Description copied from class: SystemMetrics

Sets all fields in this to values from the SystemMetrics object passed in: a _deep_ copy that shouldn't share any values with other metrics objects.

Specified by:

set in class SystemMetrics<AppWakeupMetrics>

Returns:

this

sum

public AppWakeupMetrics sum(@Nullable
                            AppWakeupMetrics b,
                            @Nullable
                            AppWakeupMetrics output)

Description copied from class: SystemMetrics

Add values from the SystemMetrics object passed in and sets them on the output object, if available. Does not modify the original object. For convenience, this function accepts null values and will allocate an output object if none is passed in.

Specified by:

sum in class SystemMetrics<AppWakeupMetrics>

Returns:

output set to (this + b)

diff

public AppWakeupMetrics diff(@Nullable
                             AppWakeupMetrics b,
                             @Nullable
                             AppWakeupMetrics output)

Description copied from class: SystemMetrics

Subtract the object passed in from the current object. Does not modify the original object. For convenience, this function accepts null values and will allocate an output object if none is passed in.

Specified by:

diff in class SystemMetrics<AppWakeupMetrics>

Returns:

output set to (this - b)
