Below is a a test program with the purpose of calling member function for each
element of the collection. Argument of this member function is a
boost::function.
I put compilation error after the source code.
Any help will be greatly appreciated.
#include

#include
typedef boost::function delegate;
class A : public boost::noncopyable
{
public:
commandhandler(delegate& f) {}
};
template <typename C> class Acoll
{
typedef boost::ptr_vector<C> ptr_container;
ptr_container m_data;
public:
typedef C CLIENT;
ptr_container& operator() (){return m_data;}
};
template <typename CLIENTS> class Test
{
CLIENTS& m_clients;
public:
delegate dosomething;
Test(CLIENTS& val) : m_clients(val) {}
void run()
{
std::for_each(m_clients().begin(), m_clients().end(),
boost::bind(&CLIENTS::CLIENT::commandhandler,
boost::ref(dosomething), _1 ));
}
};
int _tmain(int argc, _TCHAR* argv[])
{
Acoll<A> coll;
Test test(coll);
test.run();
return 0;
}
