I'm trying to play with boost::bind and boost::mem_fn, however, i
have some difficulties with the member function with more than 2
arguments. I have tried a number of time and gone through the
documentation , but still can't found an answer. Example:
#include
#include
#include
#include <iostream>
#include <vector>
#include <algorithm>
using namespace std;
class B {
public:
void print0() const {
cout << "B::print0 " << endl;
}
void print1(int i) const {
cout << "B::print1 " << i << endl;
}
void print2(int i, int j) const { // how to call??
cout << "B::print2 " << i << ' '<< j << endl;
}
};
int main()
{
typedef boost::shared_ptr<B> Ptr;
vector<Ptr> v;
for (int i = 0; i < 3; ++i) {
v.push_back(boost::shared_ptr<B>(new B()));
}
// zero argument, OK
for_each(v.begin(), v.end(), boost::mem_fn(&B::print0));
// one argument, OK
for_each(v.begin(), v.end(), boost::bind(&B::print1, _1, 5));
// two argument, how to call B::print2 ?
// for_each(v.begin(), v.end(), /* B::print2 */);
return 0;
}
Thanks for your help!
