      protected MacOperatingSystemJNA(int maxproc)

  • Method Details

    • getSystemBootTime

      public long getSystemBootTime()
      Description copied from interface: OperatingSystem
      Get Unix time of boot.
      Returns:
      The approximate time at which the system booted, in seconds since the Unix epoch.

    • getFileSystem

      public FileSystem getFileSystem()
      Description copied from interface: OperatingSystem
      Instantiates a FileSystem object.
      Returns:
      A FileSystem object.

    • getInternetProtocolStats

      public InternetProtocolStats getInternetProtocolStats()
      Description copied from interface: OperatingSystem
      Instantiates a InternetProtocolStats object.
      Returns:
      a InternetProtocolStats object.

    • queryFamilyVersionInfo

      public Pair<String, OperatingSystem.OSVersionInfo> queryFamilyVersionInfo()
      Description copied from class: AbstractOperatingSystem
      Queries the OS family and version info.
      Specified by:
      queryFamilyVersionInfo in class AbstractOperatingSystem
      Returns:
      a pair of family string and OS version info

    • getSessions

      public List<OSSession> getSessions()
      Description copied from interface: OperatingSystem
      Gets currently logged in users.

      On macOS, Linux, and Unix systems, the default implementation uses native code (see man getutxent) that is not thread safe. OSHI's use of this code is synchronized and may be used in a multi-threaded environment without introducing any additional conflicts. Users should note, however, that other operating system code may access the same native code.

      The Who#queryWho() method produces similar output parsing the output of the Posix-standard who command, and may internally employ reentrant code on some platforms. Users may opt to use this command-line variant by default using the oshi.os.unix.whocommand configuration property.

      Specified by:
      getSessions in interface OperatingSystem
      Overrides:
      getSessions in class AbstractOperatingSystem
      Returns:
      A list of OSSession objects representing logged-in users

    • queryAllProcesses

      public List<OSProcess> queryAllProcesses()
      Description copied from class: AbstractOperatingSystem
      Queries all processes on the system.
      Specified by:
      queryAllProcesses in class AbstractOperatingSystem
      Returns:
      a list of all OS processes

    • getProcess

      public OSProcess getProcess(int pid)
      Description copied from interface: OperatingSystem
      Gets information on a currently running process
      Parameters:
      pid - A process ID
      Returns:
      An OSProcess object for the specified process id if it is running; null otherwise

    • getProcessId

      public int getProcessId()
      Description copied from interface: OperatingSystem
      Gets the current process ID (PID).
      Returns:
      the Process ID of the current process

    • getProcessCount

      public int getProcessCount()
      Description copied from interface: OperatingSystem
      Get the number of processes currently running
      Returns:
      The number of processes running

    • getThreadCount

      public int getThreadCount()
      Description copied from interface: OperatingSystem
      Get the number of threads currently running
      Returns:
      The number of threads running

    • getNetworkParams

      public NetworkParams getNetworkParams()
      Description copied from interface: OperatingSystem
      Instantiates a NetworkParams object.
      Returns:
      A NetworkParams object.

    • getDesktopWindows

      public List<OSDesktopWindow> getDesktopWindows(boolean visibleOnly)
      Description copied from interface: OperatingSystem
      Gets windows on the operating system's GUI desktop.

      On Unix-like systems, reports X11 windows only, which may be limited to the current display and will not report windows used by other window managers.

      While not a guarantee, a best effort is made to return windows in foreground-to-background order. This ordering may be used along with OSDesktopWindow.getOrder() to (probably) determine the frontmost window.

      Specified by:
      getDesktopWindows in interface OperatingSystem
      Overrides:
      getDesktopWindows in class AbstractOperatingSystem
      Parameters:
      visibleOnly - Whether to restrict the list to only windows visible to the user.

      This is a best effort attempt at a reasonable definition of visibility. Visible windows may be completely transparent.

      Returns:
      A list of OSDesktopWindow objects representing the desktop windows.
