[Boost-users] Question in usage of boost::bind

2 Feb 2009

      Below is an example that fails to compile. I have a vector of pointers to a 
templated class and I need to use find_if. My understanding of boost::bind. is 
that the first argument, when binding member function, is an explicit "this" 
pointer,
that should be A* in my case. 

Any help in explaining what I am doing wrong will be greatly appreciated.

#include <algorithm>
#include <string>
#include <vector>

#include <algorithm>
#include <string>
#include <vector>

#include 

template<typename T> class A
{
	T _val;
public:
	A(T val) : _val(val){};
	T Val() {return _val;}

	bool CompareByVal(A<T>* a, int iType, T ofval)
	{
		return ( (a != NULL) && (iType == 1) && (a->Val() == ofval) );
	}
};

int _tmain(int argc, _TCHAR* argv[])
{
	std::vector  a;

	std::find_if (a.begin(), 
                       a.end(), 
                       boost::bind(&A<int>::CompareByVal, _1, _2, 1,1));
}
