Detailed Description

template<class S, typename T>
struct vcsn::MetaElement< Structure< S >, T >

The base class that glues structural elements to implementation values.

MetaElement<Structure<Self>, T> is the specialization that is at the top of all the hierarchy of Vaucanson. It inherits, and thus is decorated with, SyntacticDecorator<Self, T>.

Element< S, T > & self (   )  [inherited]

Accessor to the real type. This accessor is intended to be used by implementations in this class and derivated MetaElement specializations to obtain a reference to the Element instance with its most derivated type.
