Public Class Methods

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

5265     #puts "ifunc = " + ifunc.to_s + ",";
5266     #puts "jfunc = " + jfunc.to_s + ",";
5267     #puts "cofac = " + cofac.to_s + ",";

5270       raise "invalid arguments"
5271     end
5272     @coFac = cofac;
5273     @ifunc = ifunc;
5274     @jfunc = jfunc;
