Object oriented design suggestion

Question

Here is my code:

class Soldier {
public:
   Soldier(const string &name, const Gun &gun);
   string getName();
private:
   Gun gun;
   string name;
};

cl         


        

Answer 1

The Law of Demeter would say to encapsulate the functions.

http://en.wikipedia.org/wiki/Law_of_Demeter

This way, if you want some type of interaction between the soldier and the gun, you have a space to insert the code.

Edit: Found the relevant article from the Wikipedia link: http://www.ccs.neu.edu/research/demeter/demeter-method/LawOfDemeter/paper-boy/demeter.pdf The paperboy example is very, very similar to the soldier example you post.
