Method Details

queryPowerSources

protected List<PowerSource> queryPowerSources()

Description copied from class: AbstractPowerSource

Returns a fresh list of power sources for this platform, used by AbstractPowerSource.updateAttributes(). Each concrete subclass implements this by delegating to its own static getPowerSources() factory method.

Overrides:

queryPowerSources in class LinuxPowerSource

Returns:

A list of PowerSource objects representing batteries, etc.

getPowerSources

public static List<PowerSource> getPowerSources()

Gets Battery Information

Returns:

A list of PowerSource objects representing batteries, etc.
