This demonstrates how to pass each object in the container to a member function of different class instance using boost::bind. You can alternatively do this by overloading operator()
- include <QtConcurrentMap>
- include <QVector>
- include <boost/bind.hpp>
- include <iostream>
class Object{};
class MyClass
{
public:
float Test(const Object& object) const { return 1.0f; } // Note, this function MUST be const!
};
int main()
{
QVector<Object> v;
Object a;
v.push_back(a);
MyClass myClass;
QVector<float> result = QtConcurrent::blockingMapped<QVector<float> >(v.begin(), v.end(), boost::bind(&MyClass::Test, &myClass, _1));
std::cout << result[0] << std::endl;
return 0;
}
