## Definition

Refines
  `Functor`

Has Models:
  ArrangementXMonotoneTraits_2::Merge_2

## Operations
A model of this concept must provide:
void | merge (ArrTraits::X_monotone_curve_2 xc1, ArrTraits::X_monotone_curve_2 xc2, ArrTraits::X_monotone_curve_2 &xc)
| accepts two mergeable \( x\)-monotone curves `xc1` and `xc2` and assigns `xc` with the merged curve.

## Member Function Documentation

## ◆ merge()

void ArrTraits::Merge_2::merge | ( | ArrTraits::X_monotone_curve_2 | xc1,
|  | ArrTraits::X_monotone_curve_2 | xc2,
|  | ArrTraits::X_monotone_curve_2 & | xc
| ) |  |

accepts two mergeable \( x\)-monotone curves `xc1` and `xc2` and assigns `xc` with the merged curve.

Precondition
  `are_mergeable_2`(`xc1`, `xc2`) is true.
