Refines
  `AdaptableUnaryFunction`

Has models
  `ArrangementDirectionalXMonotoneTraits_2::Split_2`

## Operations
A model of this concept must provide:
void | 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.

## Member Function Documentation

## ◆ operator()()

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.
