FloatSnapRoundingTraits_2 Concept Reference

Definition

The concept FloatSnapRoundingTraits_2 lists the set of requirements that must be fulfilled by an instance of the Traits template-parameter of the free functions CGAL::float_snap_rounding_2() CGAL::float_snap_rounding_2<InputIterator,OutputIterator,NamedParameter>(), CGAL::compute_snapped_subcurves_2() CGAL::compute_snapped_subcurves_2<InputIterator,OutputIterator,NamedParameter>(), CGAL::compute_snapped_polygons_2() CGAL::compute_snapped_polygons_2<InputIterator,OutputIterator,NamedParameter>(). The list includes the nested types of the geometric primitives used in this class and some function object types for the required predicates on those primitives.

Evaluation_tag

typedef unspecified_type FloatSnapRoundingTraits_2::Evaluation_tag

An instance of CGAL::Boolean_tag.

If its value is true, FSRTraits_2::Evaluate is used to compute the exact values of coordinates. If its value is false then FSRTraits_2::Evaluate is not used and may be omitted.

FT

typedef unspecified_type FloatSnapRoundingTraits_2::FT

The number type.

This type must fulfill the requirements on FieldNumberType
