Return one of the stored operands in a mutable reference context.

In this case we assume that it is safe to return a reference as the storage container should be alive in a real object.

As a special exception operands for which IsTypedValue evaluates to std::true_type are always returned as copy. It is assumed that those do not contain any runtime information.

OperandType< I > && Dune::ACFem::Expressions::Storage< F, T >::operand ( IndexConstant< I >  = IndexConstant<I>{} ) &&

inlineinherited

Return one of the stored operands in an rvalue context.

In this case exactly the contained type is returned, i.e. a copy for objects or a reference for references.

As a special exception operands for which IsTypedValue evaluates to std::true_type are always returned as copy. It is assumed that those do not contain any runtime information.
