IndicatorType Dune::ACFem::BinaryGridFunctionExpression< BinOp, LeftFunction, RightFunction >::indicator ( ) const

inline

Resulting Boundary indicator type.

name()

const std::string & Dune::ACFem::GridFunctionExpression< BinaryGridFunctionExpressionTraits< BinOp, LeftFunction, RightFunction >::FunctionSpaceType , BinaryGridFunctionExpression< BinOp, LeftFunction, RightFunction > , 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< BinaryGridFunctionExpressionTraits< BinOp, LeftFunction, RightFunction >::FunctionSpaceType , BinaryGridFunctionExpression< BinOp, LeftFunction, RightFunction > , 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".
