Detailed Description

template<class SomeThing>
struct Dune::ACFem::ExpressionStorage< SomeThing >

An ExpressionStorage object stores either a copy or a reference of an object.

The default is to store copies for something which inherits from ExpressionTemplate<SomeThing> and otherwise to store references. In order to be stored as copy (thus allowing for copying temporaries in expressions) one can either inherit from ExpressionTemplate<Impl> or specialize the ExpressionStorage class for the particular object.

This way "real" non-expression objects like discrete functions etc. are stored as references, anything which claims to be an expression is copied.
