      • queryBitness

        protected int queryBitness​(int jvmBitness)
        Description copied from class: AbstractOperatingSystem
        Backup OS-specific query to determine bitness if previous checks fail
        Specified by:
        queryBitness in class AbstractOperatingSystem
        Parameters:
        jvmBitness - The bitness of the JVM
        Returns:
        The operating system bitness

      • 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

      • getProcessListFromPS

        private java.util.List<OSProcess> getProcessListFromPS​(int pid)

      • 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
        Get the System up time (time since boot).
        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.

      • querySystemBootTime

        private static long querySystemBootTime()

      • getServices

        public java.util.List<OSService> getServices()
        Description copied from interface: OperatingSystem
        Gets the all services on the system. The definition of what is a service is platform-dependent.
        Returns:
        An array of OSService objects
