Creation

A default constructor and copy constructor are defined.

Partition_traits_2<R> traits;

Partition_traits_2<R> traits ( Partition_traits_2& tr);

Operations

For each predicate object type Pred_object_type listed above (i.e., Less_yx_2, Less_xy_2, Left_turn_2, Orientation_2, Compare_y_2, Compare_x_2, Construct_line_2, Construct_ray_2, Construct_segment_2, Collinear_are_ordered_along_line_2, Are_strictly_ordered_along_line_2, Is_convex_2, Is_y_monotone_2) there is a corresponding function of the following form defined:
