Re: [Boost-users] Question regarding mem_fn or function

17 Jun 2005

      Here is a short example, that of course doesn't do anything important:

class X
{
public:
	X() {}
	~X() {}

	std::vector< int > vecInteger;

	bool Sort(int const& lhs, int const& rhs)
	{
		return lhs < rhs;
	}
};

// then either outside the body of the class:

X x;

// or inside some other class method you want to sort the vector...

// and here's the part that I don't see...

std::sort(x.vecInteger.begin(); x.vecInteger.end(),
boost::mem_fn(X::Sort)); 

Thanks,

Hi,
My imagination fails me here:
How can you use boost::mem_fn or boost::function to bind a class
member function as a predicate function for use in std::sort?  I
tried this way and that and so far, nothing.
Please post a short example.
