Detailed Description

template<class LocalFunctionImpl, class GridPart>
class Dune::ACFem::LocalFunctionWrapper< LocalFunctionImpl, GridPart >

LocalFunctionWrapper wraps a class with a local evaluate method into a grid function.

The class takes one template argument EvalImp which holds the evaluate method for the local function: template<class PointType> EvalImp::evaluate(const PointType& x,RangeType& val) Required type in LocalFunctionImpl are: FunctionSpaceType which is derived from the functionspace interface provides and provides the RangeType GridPartType providing the EntityType An instance of the EvalImp class is passed to the constructor of the wrapper and the entity to process is passed to a method init on EvalImp.

Member Function Documentation

name()

const std::string & Dune::ACFem::GridFunctionExpression< LocalFunctionImpl::FunctionSpaceType , LocalFunctionWrapper< LocalFunctionImpl, GridPart > , ExpressionTemplate >::name ( ) const

inlineinherited

Return a descriptive name for the function.

If set by setName(), return that user-supplied name. Otherwise return a (lengthy) auto-generated name describing the underlying algebraic expression.

setName()

void Dune::ACFem::GridFunctionExpression< LocalFunctionImpl::FunctionSpaceType , LocalFunctionWrapper< LocalFunctionImpl, GridPart > , ExpressionTemplate >::setName ( const std::string &  newName )

inlineinherited

Supply a descriptive name for the function.

This name will also be stored in the VTK files. It should be a "valid variable name".
