Re: [boost] [flyweight] key value with objects not constructible from a key

It would go to the factory's construct method which might look like:

void TextureFactory::construct( void* address, const std::string& filename ) { // complex work involving lots of 3rd party libraries // happens here GLuint glTextureName = LoadImage( filename );

// texture stays simple new(address) Texture( glTextureName, filename ); }

Rather than doing this, it might be more elegant to return a factory function, such as in_place or functional/factory.
