Detailed Description

template<typename S, typename T>
struct vcsn::SyntacticDecorator< S, T >

This class provides the standard operator delegations to Element.

It defines all the self-application operators of C++, and delegates them to corresponding op_* functions.

Member Function Documentation

Element< S, T > & self (   )

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.

const Element< S, T > & self (   )  const

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.
