Dune::FunctionBase< DT, RT, n, m > Class Template Reference
[Functions Hierarchy]
#include <functions.hh>
Inheritance diagram for Dune::FunctionBase< DT, RT, n, m >:
Detailed Description
template<class DT, class RT, int n, int m>
class Dune::FunctionBase< DT, RT, n, m >
Abstract base class for functions.
The mother of all functions f : DT^n -> RT^m
Template parameters are:
- DT type for components of the input vector
- RT type for the return values
- n dimension of the input space
- m number of components of the vector-valued function
Public Types | |
| enum | |
| export dimension of domain and range | |
| typedef DT | DomainFieldType |
| export type for domain components | |
| typedef RT | RangeFieldType |
| export type for range components | |
Public Member Functions | |
