template<class GV, class RT, int m>
virtual RT Dune::GridFunctionGlobalEvalDefault< GV, RT, m >::eval ( int  comp,
const Dune::FieldVector< DT, n > &  xi 
) const [inline, virtual]

implement global evaluation with local evaluation

The local entity is searched via a hierarchic search

Parameters:
[in] comp number of component to be evaluated
[in] xi point in local coordinates of the reference element of e
Returns:
value of the component

virtual RT Dune::GridFunction< GV::Grid , RT , m >::evallocal ( int  comp,
const Entity &  e,
const Dune::FieldVector< DT, n > &  xi 
) const [pure virtual, inherited]

evaluate single component comp in the entity e at local coordinates xi

Evaluate the function in an entity at local coordinates.

Parameters:
[in] comp number of component to be evaluated
[in] e reference to grid entity of codimension 0
[in] xi point in local coordinates of the reference element of e
Returns:
value of the component

virtual void Dune::GridFunction< GV::Grid , RT , m >::evalalllocal ( const Entity &  e,
const Dune::FieldVector< DT, GV::Grid ::dimension > &  xi,
Dune::FieldVector< RT , m > &  y 
) const [pure virtual, inherited]

evaluate all components in the entity e at local coordinates xi

Evaluates all components of a function at once.

Parameters:
[in] e reference to grid entity of codimension 0
[in] xi point in local coordinates of the reference element of e
[out] y vector with values to be filled

template<class DT, class RT, int n, int m>
virtual RT Dune::FunctionBase< DT, RT, n, m >::eval ( int  comp,
const Dune::FieldVector< DT, n > &  x 
) const [pure virtual, inherited]

evaluate single component comp at global point x

Evaluate a single component of the vector-valued function.

Parameters:
[in] comp number of component to be evaluated
[in] x position to be evaluated
Returns:
value of the component
