Storing objects in the array
- by Ockonal
Hello, I want to save boost signals objects in the map (association: signal name ? signal object). The signals signature is different, so the second type of map should be boost::any.
map<string, any> mSignalAssociation;
The question is how to store objects without defining type of new signal signature?
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;
All this tryings throw the error:
