bool ArrDirectionalTraits::AreMergeable_2::operator() ( ArrDirectionalTraits::X_monotone_curve_2  xc1,
ArrDirectionalTraits::X_monotone_curve_2  xc2 
)

accepts two \( x\)-monotone curves xc1 and xc2 and determines whether they can be merged to form a single \( x\)-monotone curve.

xc1 and xc2 are mergeable if their underlying curves are identical, they share a common endpoint, and they do not bend to form a non- \( x\)-monotone curve.

Precondition
The target point of xc1 and the source point xc2 coincide or the source point of xc2 and the target point xc2 coincide.
