Element transformation class, templated on a mesh type and an integration rule. It is constructed from a mesh (e.g. class TMesh) and shape evaluator (e.g. class ShapeEvaluator) objects. Allows computation of physical coordinates and Jacobian matrices corresponding to the reference integration points. The desired result is specified through the template subclass Result and stored in an object of the same type. More...
