Bonjour à tous.
J'ai un vecteur de pointeurs sur lequel j'appelle remove_if, actuellement avec un prédicat (IsDeletable). Cependant, comme ce prédicat n'est utilisé qu'ici je souhaite ne plus l'utiliser et en lieu et place utiliser des lambda-expressions.
Mon souhait est donc de remplacer

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

1
2
3
4
5
6
7
 
struct IsDeletable : public std::unary_function<Archive*, bool> {
 
	bool operator()(Archive* ar) const {
		return (ar->getState() & ArchiveState::S_CANCELLED) != 0;
	}
};

Le code que j'ai écrit jusqu'à présent est :

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

1
2
3
4
 
bind(unlambda(_1 != 0),
   (bind(unlambda(_1 & ArchiveState::S_CANCELLED),
      (bind(unlambda(_1 ->* &Archive::getState), _1)))));

Mais ce code, appelé avec un remove_if, ne passe pas la compilation, et j'ai du mal à comprendre pourquoi :

Quelqu'un peut-il éclairer ma lanterne ? Merci d'avance ! (ps : ce doit être tout bête mais je tourne en rond depuis deux heures, j'en peux plus...)

[loufoque]

Pourquoi pas, tout simplement:

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

(_1->getState() & Archive::S_CANCELLED) != 0

[Patriarch24]

Parce que l'opérateur -> n'est pas membre de boost::lambda::lambda_functor<T>.

[Patriarch24]

J'ai trouvé . En fait, il faut faire plus simple :

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

1
2
(unlambda((_1 & static_cast<int>(ArchiveState::S_CANCELLED)) != 0))
   (bind(apply<int>(), _1 ->* &Archive::getState))

Il faut utiliser apply pour appliquer la fonction (équivalent d'un funcall en Lisp).
