Title: SFML Book chapter 2 question
Post by: Michalus on August 01, 2013, 07:07:10 pm

I read at this moment the sfml development book.
I am at chapter 2 before the headline Error handling.
There stand at the TextureHolder class, two get methods
first:

sf::Texture& get (Textures::ID id);
 

second:

const sf::Texture& get (Textures::ID id) const;
 

But I dont understand the sense of the second method.
The methods do  actually almost the same.

Yes they do almost the same. So what's the difference? What do those const mean? ;)
