      • random

        public static double random()
        Returns a random double number.
        Returns:
        a random double number

      • randomInteger

        public static int randomInteger()
        Returns a random integer number.
        Returns:
        a random integer number

      • randomInteger

        public static int randomInteger​(int max)
        Returns a random integer number between 0 and max (exclusive).
        Parameters:
        max - the maximum (exclusive) value
        Returns:
        the random integer number

      • createIntegerSequence

        public static Sequence<java.lang.Integer> createIntegerSequence​(int start,
                                                                int end)
        Creates a sequence from start to end. Caution: This is currently a real enumeration intended for simple loops. To be more efficient, a wrapper implementation for the range from start to end shall be implemented and used instead.
        Parameters:
        start - the start integer
        end - the end integer
        Returns:
        a random double number

      • println

        public static void println​(java.lang.Object object)
        Just prints to the instantiator tracer.
        Parameters:
        object - the object to be printed
