CGAL::Classification::Cluster< ItemRange, ItemMap > Class Template Reference

#include <CGAL/Classification/Cluster.h>

Definition

template<typename ItemRange, typename ItemMap>
class CGAL::Classification::Cluster< ItemRange, ItemMap >

Class that represent a cluster of items to be classified as a single atomic object.

A cluster is a set of indices of items inside an input range with random access.

Template Parameters

ItemRange	model of ConstRange. Its iterator type is RandomAccessIterator. Its value type depends on the data that is classified (for example, CGAL::Point_3 or CGAL::Triangle_3).
ItemMap	model of ReadablePropertyMap whose key type is the value type of the iterator of ItemRange and value type is the type of item to classify (for example, CGAL::Point_3).

Public Types
using	Item = typename boost::property_traits< ItemMap >::value_type

Constructor
	Cluster (const ItemRange &range, ItemMap item_map)
	Constructs an empty cluster of items.

Modifications
void	clear ()
	Clears the cluster.
void	insert (std::size_t idx)
	inserts element of index idx in the cluster.

Access
std::size_t	size () const
	returns the number of items in the cluster.
std::size_t	index (std::size_t i) const
	returns the index (in the input range) of the i^{th} element of the cluster.
const Item &	operator[] (std::size_t i) const
	returns the i^{th} item of the cluster.
const CGAL::Bbox_3 &	bbox () const
	returns the bounding box of the cluster.

Classification
int	training () const
	returns the input classification value used for training.
int &	training ()
	returns a reference to the input classification value used for training.
int	label () const
	returns the output classification value.
int &	label ()
	returns a reference to the output classification value.

Constructor & Destructor Documentation

Cluster()

template<typename ItemRange , typename ItemMap >

CGAL::Classification::Cluster< ItemRange, ItemMap >::Cluster	(	const ItemRange &	range,
		ItemMap	item_map
	)

Constructs an empty cluster of items.

Items in the clusters will be subsets of range.

Parameters

range	input range.
item_map	property map to access the input items.
