Public Member Functions
	vector_dist_expression_op (const exp1 &o1, const vector_type &vd)
	constructor from an epxression exp1 and a vector vd
void	init () const
	sum reduction require initialization where we calculate the reduction
std::remove_reference< rtype > ::type	get ()
	it return the result of the expression
template<typename r_type = typename std::remove_reference<rtype>::type>
r_type	value (const vect_dist_key_dx &key) const
	it return the result of the expression (precalculated before)

Private Types
typedef apply_kernel_rtype < decltype(o1.value(vect_dist_key_dx()))> ::rtype	rtype
	return type of this expression

Private Attributes
const exp1	o1
	expression on which apply the reduction
std::remove_reference< rtype > ::type	val
	return type of the calculated value (without reference)
const vector_type &	vd
	vector on which we apply the reduction expression
