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

5023 def initialize(ifunc,jfunc,cofac=nil)
5024     #puts "ifunc = " + ifunc.to_s + ",";
5025     #puts "jfunc = " + jfunc.to_s + ",";
5026     #puts "cofac = " + cofac.to_s + ",";
5027     super();
5028     if jfunc == nil && cofac == nil 
5029       raise "invalid arguments"
5030     end
5031     @coFac = cofac;
5032     @ifunc = ifunc;
5033     @jfunc = jfunc;
