#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

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.
