[Boost-users] How can I use Boost bind library

14 Feb 2006

      I have a function in STL which add the 'area'
attribute of a list of Rect.

float getTotalAreaPerCent(BlockDataList& bdl) {
  return   accumulate (bdl.begin(), bdl.end(), 0.0,
add_area_per_cent<BlockData*, float>());
}

template< class T1, class T2> class add_area_per_cent
: public binary_function<T2, T1,  T2>
{
	public:
		add_area_per_cent() { }

	 	T2 operator() (T2 initial, T1 element) { 
		  if (element != NULL) {
  			return initial + element->getAreaPerCent();
		  } else {
		    return initial;
		  }
  		}

};

Can you please tell me how can I reduce the amount of
code and use Boost bind library to achieve the same
thing?

Thank you.
