CGAL 5.5.2 - 2D and 3D Linear Geometry Kernel

Inherited by CGAL::Circular_kernel_2< class, class >, and CGAL::Spherical_kernel_3< class, class >.

Definition

The concept of a kernel is defined by a set of requirements on the provision of certain types and access member functions to create objects of these types. The types are function object classes to be used within the algorithms and data structures of CGAL. This allows you to use any model of a kernel as a traits class in the CGAL algorithms and data structures, unless they require types beyond those provided by a kernel.

A kernel provides types, construction objects, and generalized predicates. The former replace constructors of the kernel classes and constructive procedures in the kernel. There are also function objects replacing operators, especially for equality testing.

Naming convention of constructions
All constructions which result type is a geometric object are prefixed by Construct_. If the result type is a number type, the name is prefixed by Compute_. When the result type is not determined, no prefix is used.

Has Models:

CGAL::Cartesian<FieldNumberType>

CGAL::Homogeneous<RingNumberType>

CGAL::Simple_cartesian<FieldNumberType>

CGAL::Simple_homogeneous<RingNumberType>

CGAL::Filtered_kernel<CK>

CGAL::Exact_predicates_exact_constructions_kernel

CGAL::Exact_predicates_exact_constructions_kernel_with_sqrt

CGAL::Exact_predicates_inexact_constructions_kernel

Types

The following types describe the return types of predicates.

They typically map to bool and CGAL kernel enum types, except when an interval arithmetic number type is used such as within the filtering kernels, in which case it is Uncertain<bool> or similar.

Operations

For each of the function objects above, there must exist a member function that requires no arguments and returns an instance of that function object.

The name of the member function is the uncapitalized name of the type returned with the suffix _object appended. For example, for the function object Kernel::Construct_vector_2 the following member function must exist:

Kernel::Construct_vector_2 construct_vector_2_object () const

◆ Has_filtered_predicates

const bool Kernel::Has_filtered_predicates
static

A Boolean value indicating whether the predicates are filtered (as in CGAL::Filtered_kernel).

This helps propagating such decisions to traits classes which are built on top of a kernel, so that they can decide to filter their own predicates or not.
