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>.
