Detailed Description

template<class Range, class Domain, class LocalContext, template< class > class DerivativeTraits, size_t bufferSize>
class Dune::Functions::LocalFunction< Range(Domain), LocalContext, DerivativeTraits, bufferSize >

Class storing local functions using type erasure.

Template Parameters

Range	Range type
Domain	Domain type
LocalContext	Type of local context where this function is defined on
DerivativeTraits	Traits class to determine range of derivative.
bufferSize	Size of stack buffer for small object optimization (defaults to 56)

This models the Concept::LocalFunction<Range(Domain), LocalContext, DerivativeTraits> concept. Objects of this type are returned as local functions by the GridFunction wrapper. Notice that the DerivativeTraits type used here should normally be LocalDerivativeTraits<E,GDE> where GDE is the DerivativeTraits type of the corresponding global function. Small object optimization is used to store the given function. If its size exceed bufferSize, memory will be allocated dynamically.

Constructor & Destructor Documentation

LocalFunction() [1/2]

template<class Range , class Domain , class LocalContext , template< class > class DerivativeTraits, size_t bufferSize>

template<class F , disableCopyMove< LocalFunction, F > = 0>

Dune::Functions::LocalFunction< Range(Domain), LocalContext, DerivativeTraits, bufferSize >::LocalFunction ( F &&  f )

inline

Construct from function.

Template Parameters

F	Function type

Parameters

f	Function of type F

Calling derivative(DifferentiableFunction) will result in an exception if the passed function does provide a free derivative() function found via ADL.

LocalFunction() [2/2]

template<class Range , class Domain , class LocalContext , template< class > class DerivativeTraits, size_t bufferSize>

Dune::Functions::LocalFunction< Range(Domain), LocalContext, DerivativeTraits, bufferSize >::LocalFunction ( )

default

Member Function Documentation

bind()

template<class Range , class Domain , class LocalContext , template< class > class DerivativeTraits, size_t bufferSize>

void Dune::Functions::LocalFunction< Range(Domain), LocalContext, DerivativeTraits, bufferSize >::bind ( const LocalContext &  context )

inline

Bind function to a local context.

You must bind a LocalFunction to a local context before you can evaluate it.

bound()

template<class Range , class Domain , class LocalContext , template< class > class DerivativeTraits, size_t bufferSize>

bool Dune::Functions::LocalFunction< Range(Domain), LocalContext, DerivativeTraits, bufferSize >::bound ( ) const

inline

Return if the local function is bound to a grid element.

localContext()

template<class Range , class Domain , class LocalContext , template< class > class DerivativeTraits, size_t bufferSize>

const LocalContext & Dune::Functions::LocalFunction< Range(Domain), LocalContext, DerivativeTraits, bufferSize >::localContext ( ) const

inline

Obtain local context this LocalFunction is bound to.

operator()()

template<class Range , class Domain , class LocalContext , template< class > class DerivativeTraits, size_t bufferSize>

Range Dune::Functions::LocalFunction< Range(Domain), LocalContext, DerivativeTraits, bufferSize >::operator() ( const Domain &  x ) const

inline

Evaluation of wrapped function.

unbind()

template<class Range , class Domain , class LocalContext , template< class > class DerivativeTraits, size_t bufferSize>

void Dune::Functions::LocalFunction< Range(Domain), LocalContext, DerivativeTraits, bufferSize >::unbind ( )

inline

Unbind from local context.
