All Implemented Interfaces:
Runnable
public class Device extends JposDevice implements Runnable
JposDevice based implementation of JavaPOS POSPower device service implementation for the battery power devices in Windows laptops, notebooks and tablets.

This implementation uses the following WIN32 API functions:

  • GetSystemPowerStatus,
  • SetSuspendState
and the Windows program shutdown.exe.

Here a full list of all device specific properties that can be changed via jpos.xml:

  • PollDelay: Minimum time between status requests, in milliseconds. Status requests will be used to monitor the device state. Default: 1000.
  • SecondsToFinish: Number of seconds between shutdown activation and shutdown. Will be used with command line parameter "-t" of the shutdown command. Default: 1.

  • Constructor Details

    • Device

      public Device​(String id)
      The device implementation. See parent for further details.
      Parameters:
      id - Device ID, not used by POSPower implementation. Can be any value.
