    • 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

    • 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.

    • getThreadCount

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

    • getSystemUptime

      public long getSystemUptime()
      Description copied from interface: OperatingSystem

      Returns:
      Number of seconds since boot.

    • 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.

    • getNetworkParams
