Hello, I'm currently working to improve the package I introduced here : https://www.ultimatepp.org/forums/index.php?t=msg&th=111 48&start=0&

To improve it and add new functionnality / modularity I started to write bunch of new class:

One of them is named Context and hold a private Vector of Scene Object. Some of public methods allow user to Create/Remove/Get all the scene object depending on ID (int):

Scene& CreateScene(); //Return the fresh created scene
bool RemoveScene(int sceneId);
Scene& GetScene(int sceneId); //Return scene depending on ID

2 questions come in my head when reviewing this code
-First one : Is it good to return reference of Scene in CreateScene() ? the fact a Vector is holding Scene mean the reference can get dereferenced at next creation/ destruction, on other hand returning the ID of the scene in CreateScene() force user to call GetScene(int sceneId) (which could lead to the same behavior) May I should use Array instead of Vector and return Reference ? What you think ?

-Second one : Since ID is (in term of human view) less simple to remember, is it a good idea to swap int ID to String name, and use name to identify all Scene ?
