Detailed Description
template<typename S>
struct vcsn::Structure< S >
Base class for the hierarchy of structural element types.
It provides:
- static inheritance facilities,
- the concept of compatibility between elements and a structural element considered as a set (through the
contains()method), - a
choose()method to pick randomlyElementinstances.

Member Function Documentation
| bool contains | ( | const Element< OtherS, T > & | other | ) | const [inline] |
Specialization of contains that always returns false.
Indeed, elements structured by a particular type are always incompatible with structural elements of another type.
Definition at line 47 of file structure.hxx.
| S & self | ( | ) | [inline] |
Accessor to the real type.
To be used by implementations in this class and derived structures to obtain a reference to the structural element with its most derived type.
