Default About code on page 182

On the top of the page 182, in the fisrt code snippet, one of the line reads :

int getId() const;

I have issue with this specific line
Indeed I do not understand the use of "const" on this line
Could one of you help me understand the line (I may have missed one point somewhere)

Best regards, Philippe

Forget my question
I knew it was a bad idea

Const is there because getId is an Inspector
See p 33 for details if needed

Sorry for the post.

Correct, getId() is an inspector and does not change any data members of the class, so it's const.
