Definition

This is an advanced concept.

Advanced

The concept Splitter defines the requirements for a function object class implementing a splitting rule.

Has models

Examples

Spatial_searching/searching_polyhedron_vertices.cpp, Spatial_searching/searching_surface_mesh_vertices.cpp, Spatial_searching/searching_triangulation_vertices.cpp, Spatial_searching/searching_with_point_with_info_inplace.cpp, and Spatial_searching/searching_with_point_with_info_pmap.cpp.

Types
The parameters aspect_ratio and bucket_size define the way in which \(k\) - \(d\) tree is constructed.
typedef unspecified_type	FT
	Number type.
typedef unspecified_type	Separator
	Separator.
typedef unspecified_type	Container
	Typedef to an instantiation of CGAL::Point_container<Traits>.

Operations
FT	aspect_ratio () const
	Returns the maximal ratio between the largest and smallest side of a cell allowed for fair splitting.
unsigned int	bucket_size () const
	Returns the bucket size of the leaf nodes.
void	operator() (Separator &sep, Container &c0, Container &c1) const
	Sets up sep and splits points of c0 into c0 and c1 using sep.

Member Function Documentation

operator()()

void Splitter::operator()	(	Separator &	sep,
		Container &	c0,
		Container &	c1 ) const

Sets up sep and splits points of c0 into c0 and c1 using sep.

Container c0 should contain at least two points and c1 must be empty.
