void ArrDirectionalTraits::Split_2::operator()	(	ArrDirectionalTraits::X_monotone_curve_2	xc,
		ArrDirectionalTraits::Point_2	p,
		ArrDirectionalTraits::X_monotone_curve_2 &	xc1,
		ArrDirectionalTraits::X_monotone_curve_2 &	xc2
	)

accepts an input curve xc and a split point p in its interior.

It splits xc at the split point into two subcurves xc1 and xc2, such that p is xc1's right endpoint and xc2's left endpoint. The direction of xc is preserved. That is, in case xc is directed from left to right, p becomes xc1's target and c2's source; otherwise, p becomes xc2's target and xc1's source.
