Detailed Description

template<typename DGBF>
class Dune::Functions::DiscreteGlobalBasisFunctionDerivative< DGBF >::LocalFunction

local function evaluating the derivative in reference coordinates

Note that the function returns the derivative with respect to global coordinates even when the point is given in reference coordinates on an element.

Constructor & Destructor Documentation

LocalFunction()

template<typename DGBF >

Dune::Functions::DiscreteGlobalBasisFunctionDerivative< DGBF >::LocalFunction::LocalFunction ( const GlobalFunction &  globalFunction )

inline

Create a local function from the associated grid function.

Member Function Documentation

assignWith()

template<typename B , typename V , typename NTRE >

template<class To , class From >

void Dune::Functions::ImplDoc::DiscreteGlobalBasisFunctionBase< B, V, NTRE >::LocalFunctionBase::assignWith ( To &  to, const From &  from  ) const

inlineprotectedinherited

bind()

template<typename DGBF >

void Dune::Functions::DiscreteGlobalBasisFunctionDerivative< DGBF >::LocalFunction::bind ( const Element &  element )

inline

Bind LocalFunction to grid element.

You must call this method before operator() and after changes to the coefficient vector.

bound()

template<typename B , typename V , typename NTRE >

bool Dune::Functions::ImplDoc::DiscreteGlobalBasisFunctionBase< B, V, NTRE >::LocalFunctionBase::bound ( ) const

inlineinherited

Check if LocalFunction is already bound to an element.

localContext()

template<typename B , typename V , typename NTRE >

const Element & Dune::Functions::ImplDoc::DiscreteGlobalBasisFunctionBase< B, V, NTRE >::LocalFunctionBase::localContext ( ) const

inlineinherited

Return the element the local-function is bound to.

nodeToRangeEntry()

template<typename B , typename V , typename NTRE >

template<class Node , class TreePath , class Range >

decltype(auto) Dune::Functions::ImplDoc::DiscreteGlobalBasisFunctionBase< B, V, NTRE >::LocalFunctionBase::nodeToRangeEntry ( const Node &  node, const TreePath &  treePath, Range &  y  ) const

inlineprotectedinherited

operator()()

template<typename DGBF >

Range Dune::Functions::DiscreteGlobalBasisFunctionDerivative< DGBF >::LocalFunction::operator() ( const Domain &  x ) const

inline

Evaluate this local-function in coordinates x in the bound element.

The result of this method is undefined if you did not call bind() beforehand or changed the coefficient vector after the last call to bind(). In the latter case you have to call bind() again in order to make operator() usable.

Note that the function returns the derivative with respect to global coordinates even when the point is given in reference coordinates on an element.

unbind()

template<typename DGBF >

void Dune::Functions::DiscreteGlobalBasisFunctionDerivative< DGBF >::LocalFunction::unbind ( )

inline

Unbind the local-function.
