I'm going through [1] to construct a new algebraic structure. I have one parent, but want more than one elements, which should be associated to this parent. More precisely, I have the following classes:
+- MyElementBase +-- MyElementA (derived from MyElementBase) +-- MyElementB (derived from MyElementBase) In [1] it says, we should use return self.element_class(data) in Parent._element_constructor_ to create objects. This creates a class derived from Parent.Element (which IMHO should be MyElementBase) and Parent.category().element_class. How can I create "the correct" instance of MyElementA and MyElementB inside _element_constructor_ depending on the input? (I want to do this, since MyElementA is a specialized version of MyElementBase for some inputs; similar MyElementB) Daniel [1] http://www.sagemath.org/doc/thematic_tutorials/coercion_and_categories.html -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
