Enregistrement d'objets dans la matrice

Question

Je souhaite enregistrer des objets de signaux boost dans la carte (association: nom du signal → objet signal). La signature des signaux est différente, donc le deuxième type de carte doit être boost :: any.

map<string, any> mSignalAssociation; 

La question est de savoir comment stocker des objets sans définir le type de nouvelle signature de signal?

typedef boost::signals2::signal<void (int KeyCode)> sigKeyPressed; 
mSignalAssociation.insert(make_pair("KeyPressed", sigKeyPressed())); 
// This is what I need: passing object without type definition 
mSignalAssociation["KeyPressed"] = (typename boost::signals2::signal<void (int KeyCode)>()); 
// One more trying which won't work. And I don't want use this 
sigKeyPressed mKeyPressed; 
mSignalAssociation["KeyPressed"] = mKeyPressed; 

Tout cela tryings jeter l'erreur:

Cela n'a rien à voir avec any ou map. Les signaux Boost sont simplement non-copiables. Vous pouvez les envelopper dans un pointeur intelligent tel que shared_ptr si vous voulez quelque chose qui est copiable et nettoie après lui-même.
