LargestEmptyIsoRectangleTraits_2 Concept Reference

Definition

The concept LargestEmptyIsoRectangleTraits_2 describes the set of requirements to be fulfilled by any class used to instantiate the template parameter of the class Largest_empty_iso_rectangle_2<T>. This concept provides the types of the geometric primitives used in this class and some function object types for the required predicates on those primitives.

Has Models:

Member Typedef Documentation

◆ Compare_x_2

Predicate object.

Must provide the operator Comparison_result operator()(Point_2 p, Point_2 q) which returns SMALLER, EQUAL or LARGER according ding to the \( x\)-ordering of points p and q.

◆ Compare_y_2

Predicate object.

Must provide the operator Comparison_result operator()(Point_2 p, Point_2 q) which returns SMALLER, EQUAL or LARGER according to the \( y\)-ordering of points p and q.

◆ Less_x_2

Predicate object.

Must provide the operator bool operator()(Point_2 p, Point_2 q) which returns whether p is less than q according to their \( x\)-ordering.

◆ Less_y_2

Predicate object.

Must provide the operator bool operator()(Point_2 p, Point_2 q) which returns whether p is less than q according to their \( y\)-ordering.
