Methods

JAS::WordPolyRing

Represents a JAS non-commutative polynomial ring: GenWordPolynomialRing.

Provides more convenient constructor. Then returns a Ring. Note: watch your step: check that jruby does not reorder multiplication.

Ring constructor.

coeff = factory for coefficients, vars = string with variable names.

def initialize(coeff,vars)
    if coeff == nil
        raise ArgumentError, "No coefficient given."
    end
    cf = coeff;
    if coeff.is_a? RingElem
        cf = coeff.elem.factory();

    if vars.is_a? String
        names = GenPolynomialTokenizer.variableList(vars);
    end
    wf = WordFactory.new(names);
    @ring = GenWordPolynomialRing.new(cf, wf);
