Class PowerProfileMonitor

All Implemented Interfaces:
PointerInterface

public class PowerProfileMonitor extends Interface
#GPowerProfileMonitor makes it possible for applications as well as OS components
to monitor system power profiles and act upon them. It currently only exports
whether the system is in “Power Saver” mode (known as “Low Power” mode on
some systems).

When in “Low Power” mode, it is recommended that applications:
- disable automatic downloads;
- reduce the rate of refresh from online sources such as calendar or
email synchronisation;
- reduce the use of expensive visual effects.

It is also likely that OS components providing services to applications will
lower their own background activity, for the sake of the system.

There are a variety of tools that exist for power consumption analysis, but those
usually depend on the OS and hardware used. On Linux, one could use `upower` to
monitor the battery discharge rate, `powertop` to check on the background activity
or activity at all), `sysprof` to inspect CPU usage, and `intel_gpu_time` to
profile GPU usage.

Don't forget to disconnect the #GPowerProfileMonitor::notify::power-saver-enabled
signal, and unref the #GPowerProfileMonitor itself when exiting.

    • getClassHandler

      public static ClassHandler getClassHandler()
    • getPowerSaverEnabled

      public boolean getPowerSaverEnabled()
      Gets whether the system is in “Power Saver” mode.

      You are expected to listen to the
      #GPowerProfileMonitor::notify::power-saver-enabled signal to know when the profile has
      changed.
      Returns:
      Whether the system is in “Power Saver” mode.
    • dupDefault

      public static PowerProfileMonitor dupDefault()
      Gets a reference to the default #GPowerProfileMonitor for the system.
      Returns:
      a new reference to the default #GPowerProfileMonitor
