Application Security Testing: An Integral Part of DevOps

Use the Generic Accessors Class

Generally, from an OOP perspective, the direct access to data members should be prevented. This is why we use accessors:
Class UserDetails
    string getUserName() const;
    void setUserName(const string& name);
    string getUserLastName() const; 
    void setUserLastName(const string& name);
    string userName;
    string userLastName;

Using this technique gets tricky in the case of a changeable class. For every member you we add, you have to implement its accessors. This can get tedious if you've got a lot of members.

In this case, you can use the 'generic accessors class'. This class allows you to change the class structure without any modification:
Class GenericDataHolder : public map<string,string>
    string get(const string& paramName) 
        string ret("");
        iterator iter = find(paramName);
        if (iter!=end())
            ret = (*iter).second;
       return ret;
    void set(const string& paramName,const string& value) 
Class UserDetails : public GenericDataHolder 
void main()
    UserDetails details;
    details.set("Age","10" );
