Definition

The class Arr_consolidated_curve_data_traits_2 is a model of the concept ArrangementTraits_2, and serves as a decorator class that enables the extension of the curve type defined by the Traits parameter.

The traits class inherits its point type from Traits::Point_2, and defines the types Curve_2 and X_monotone_curve_2 extended with extraneous data fields of type Data.

Each Curve_2 object is associated with a single data field of type Data, and each X_monotone_curve_2 object is associated with a set of unique data objects. When a curve is subdivided into \( x\)-monotone subcurves, all resulting subcurves are associated with a list containing a single data object, copied from the inducing curve. When an \( x\)-monotone curve is split, its data set is duplicated, and inserted into the sets of both resulting subcurves. In case two (or more) \( x\)-monotone curves overlap, their data sets are consolidated, and are inserted into the set of the \( x\)-monotone curve that represents the overlap.
