Detailed Description

template<class L, class T>
class vcsn::algebra::AlphabetDecorator< L, T >

Decorate a given alphabet implementation with meta-symbols.

The meta-symbols are:

• a 'joker' which symbolizes every letter of the alphabet,
• a 'discard' which symbolizes every letter that is not in the alphabet but of the same letter type.

The meta-symbols are encoded using the type of the letter with a default value that has to be specified with the traits meta_symbol. For instance, '?' and '#' for char. Yet, if these characters are already present in the alphabet, we look for another character in a incremental way. If, unfortunately, there is not enough place, the program is stopped.
