    • getThreadId

      public int getThreadId()
      Description copied from interface: OperatingSystem
      Makes a best effort to get the current thread ID (TID). May not be useful in a multithreaded environment. The thread ID returned may have been short lived and no longer exist.

      Thread IDs on macOS are not correlated with any other Operating System output.

      Returns:
      the Thread ID of the current thread if known, 0 otherwise.

    • getCurrentThread

      public OSThread getCurrentThread()
      Description copied from interface: OperatingSystem
      Makes a best effort to get the current thread. May not be useful in a multithreaded environment. The thread returned may have been short lived and no longer exist.

      On macOS, returns the oldest thread in the calling process.

      Returns:
      the current thread if known; an invalid thread otherwise.

    • getSystemUptime

      public long getSystemUptime()
