ConvexPartitionIsValidTraits_2 Concept Reference

Definition

Requirements of a traits class used by convex_partition_is_valid_2 for testing the validity of a convex partition of a polygon.

Has models

CGAL::Partition_traits_2<R>

Types
All types required by the concept PartitionIsValidTraits_2 are required except the function object type Is_valid. The following type is required instead:
typedef unspecified_type	Is_convex_2
	Model of the concept PolygonIsValid that tests if a sequence of points is convex or not.

Creation
Only a copy constructor is required.
	ConvexPartitionIsValidTraits_2 (ConvexPartitionIsValidTraits_2 tr)

Operations
The following function that creates an instance of the above predicate object type must exist instead of the function is_valid_object required by PartitionIsValidTraits_2.
Is_convex_2	is_convex_2_object (ConvexPartitionIsValidTraits_2 tr)
