Detailed Description
template<class S>
struct vcsn::algebra::AlphabetSetBase< S >
Base class for structural elements of alphabets.
This class is empty and should be used for typing purposes only.
Note that implementation types for alphabets should provide:
op_choose(AlphabetSet, T), which creates a random alphabet.op_eq(AlphabetSet, T), which tests for equality between alphabets.

Member Function Documentation
| bool contains | ( | const Element< OtherS, T > & | other | ) | const [inline, inherited] |
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, inherited] |
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.
Definition at line 70 of file structure.hxx.
