      • numberOfSubcycleGenerators

        int numberOfSubcycleGenerators()
        Returns:
        the number of subcycle generators.

      • get

        TwoCmres.Cmres get​(int index)
        Parameters:
        index - Index into the list of available generators.
        Returns:
        the subcycle generator entry at index index.

      • getIfDifferent

        TwoCmres.Cmres getIfDifferent​(int index,
                              int other)
        Get the generator at index if the other index is different.

        This method exists to raise an exception before invocation of the private constructor; this mitigates Finalizer attacks (see SpotBugs CT_CONSTRUCTOR_THROW).

        Parameters:
        index - Index into the list of available generators.
        other - Other index.
        Returns:
        the subcycle generator entry at index index.

      • add

        private static void add​(long multiply,
                        int rotate,
                        int start)
        Adds an entry to the TABLE.
        Parameters:
        multiply - Multiplier.
        rotate - Rotate.
        start - Cycle start.

      • checkUnique

        static void checkUnique​(java.util.List<TwoCmres.Cmres> table,
                        long multiply)
        Check the multiply parameter is unique (not contained in any entry in the provided table).
        Parameters:
        table - the table
        multiply - the multiply parameter
