#include <CGAL/Partition_is_valid_traits_2.h>

Inherits from

Traits.

Definition

Class that derives a traits class for partition_is_valid_2() from a given traits class by defining the validity testing function object in terms of a supplied template parameter.

Is Model Of:
PartitionIsValidTraits_2

Example

See the example presented with the function optimal_convex_partition_2() for an illustration of the use of this traits class.

Types
