C++ privately contructed class
- by Nona Urbiz
How can I call a function and keep my constructor private? If I make the class static, I need to declare an object name which the compiler uses to call the constructor, which it cannot if the constructor is private (also the object would be extraneous). Here is the code I am attempting to use (it is not compilable):
I want to keep the constructor private because I will later be doing a lot of checks before adding an object, modifying previous objects when all submitted variables are not unique rather than creating new objects.
#include <iostream>
#include <fstream>
#include <regex>
#include <string>
#include <list>
#include <map>
using namespace std;
using namespace tr1;
class Referral
{
public:
string url;
map<string, int> keywords;
static bool submit(string url, string keyword, int occurrences)
{
//if(Referrals.all.size == 0){
// Referral(url, keyword, occurrences);
//}
}
private:
list<string> urls;
Referral(string url, string keyword, int occurrences)
{
url = url;
keywords[keyword] = occurrences;
Referrals.all.push_back(this);
}
};
struct All
{
list<Referral> all;
}Referrals;
int main()
{
Referral.submit("url", "keyword", 1);
}
