Const_cast on a this pointer - would I get told off by other C++ coders for doing this?
- by BeeBand
I have a class Game e.g.
class Game
{
public:
InitObjects();
...
};
And I have another class Grid, that needs to be initialised with a non-const reference to that Game object. ( A Grid object needs to call functions that can update a Game object ).
class Grid
{
public:
Grid(Game & g):
game(g){}
...
private:
Game & game;
...
};
The Game object is responsible for initialising the Grid. I did this:
void Game::InitObjects()
{
grid = new Grid(*(const_cast<Game*>(this)) );
}
grid is not a member of a Game - it's a global ( argh - i know... I don't mind making it a member, but I have the same problem right? ).
Can some seasoned C++ folk tell me if this odd looking const_cast is acceptable?
