Detailed Description

template<class F>
class Dune::Functions::CallableFunctionWrapper< F >

Wrap a Dune::VirtualFunction into a callable object.

Template Parameters

F	Some function deriving from Dune::VirtualFunction

This class provides an operator() that forwards to the evaluate method. In order to allow this F::RangeType must be default constructible. This class is copyable and ownership policy of the wrapped function (see constructors) will be the same for all copies.

This models the Concept::DifferentiableFunction<Range(Domain), DerivativeTraits> concept.

Using this wrapper you can e.g. pass a Dune::VirtualFunction<D,R> to the standard wrapper std::function<R(D)>.

Constructor & Destructor Documentation

CallableFunctionWrapper() [1/2]

template<class F >

Dune::Functions::CallableFunctionWrapper< F >::CallableFunctionWrapper ( const F &  f )

inline

Instantiate from reference to f.

The CallableFunctionWrapper will not take ownership of the provided function.

CallableFunctionWrapper() [2/2]

template<class F >

Dune::Functions::CallableFunctionWrapper< F >::CallableFunctionWrapper ( const std::shared_ptr< const F > &  f )

inline

Instantiate from std::shared_ptr to f.

The CallableFunctionWrapper will share ownership with the provided function.

Member Function Documentation

operator()()

template<class F >

Range Dune::Functions::CallableFunctionWrapper< F >::operator() ( const Domain &  x ) const

inline

Forward operator() to F::evaluate()

This uses the default constructor of F::RangeType
