Class LinuxOperatingSystemFFM

java.lang.Object
oshi.software.common.AbstractOperatingSystem
oshi.software.common.os.linux.LinuxOperatingSystem
oshi.software.os.linux.LinuxOperatingSystemFFM
All Implemented Interfaces:
oshi.software.os.OperatingSystem
@ThreadSafe public class LinuxOperatingSystemFFM extends oshi.software.common.os.linux.LinuxOperatingSystem
FFM-based Linux operating system implementation.

Extends LinuxOperatingSystem, overriding methods to use FFM implementations as they become available.

Udev availability is determined by UdevFunctions.isAvailable(), which checks both the oshi.os.linux.allowudev configuration property and whether libudev could be loaded and all symbols bound. FFM consumer classes should import HAS_UDEV from this class rather than from LinuxOperatingSystemJNA.

  • Field Details

    • HAS_UDEV

      public static final boolean HAS_UDEV
      Identifies if the udev library was successfully loaded and all symbols bound via FFM. Also respects the oshi.os.linux.allowudev configuration property, consistent with the JNA-based LinuxOperatingSystemJNA#HAS_UDEV.
