YMonotonePartitionIsValidTraits_2 Concept Reference
Concepts

Definition

Requirements of a traits class that is used by y_monotone_partition_is_valid_2 for testing the validity of a \( y\)-monotone partition of a polygon.

Has Models:
CGAL::Partition_traits_2<R>
See Also
CGAL::partition_is_valid_2()
CGAL::y_monotone_partition_2()

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_y_monotone_2
 Model of the concept PolygonIsValid that tests if a sequence of points is \( y\)-monotone or not.
 

Creation

Only a copy constructor is required.

 YMonotonePartitionIsValidTraits_2 (YMonotonePartitionIsValidTraits_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_y_monotone_2 is_y_monotone_2_object (YMonotonePartitionIsValidTraits_2 tr)
