new(ifunc,jfunc,cofac=nil) click to toggle source

Constructor.

ifunc(int i) must return a value which is used in ((RingFactory)cofac).fromInteger(). jfunc(int i) must return a value of type ring.coFac.

Calls superclass method

    #puts "ifunc = " + ifunc.to_s + ",";
    #puts "jfunc = " + jfunc.to_s + ",";
