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.
All types required by the concept PartitionIsValidTraits_2 are required except the function object type Is_valid. The following type is required instead:
YMonotonePartitionIsValidTraits_2::Is_y_monotone_2 | |
Model of the concept PolygonIsValid that tests if
a sequence of points is y-monotone or not.
|
Only a copy constructor is required.
YMonotonePartitionIsValidTraits_2 traits ( & tr); |
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 | traits.is_y_monotone_2_object ( t) |
CGAL::partition_is_valid_2
CGAL::y_monotone_partition_2
