Suppose I want to create a custom subclass of a polynomial ring. >From which class should it inherit? It should not care so much about the eventual base ring.
I'm a sage development newbie. Where can I read about the class hierarchy for sage polynomials? I'm a little confused at the organizational principle behind the following output. sage: R = PolynomialRing(QQ,['x']) sage: R.__class__ <class 'sage.rings.polynomial.polynomial_ring.PolynomialRing_field_with_category'> sage: R.an_element().__class__ <type 'sage.rings.polynomial.polynomial_rational_flint.Polynomial_rational_flint'> sage: S = PolynomialRing(QQ,['x','y']) sage: S.__class__ <type 'sage.rings.polynomial.multi_polynomial_libsingular.MPolynomialRing_libsingular'> sage: S.an_element().__class__ <type 'sage.rings.polynomial.multi_polynomial_libsingular.MPolynomial_libsingular'> --Mark -- To post to this group, send an email to sage-devel@googlegroups.com To unsubscribe from this group, send an email to sage-devel+unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-devel URL: http://www.sagemath.org
