NeighborQuery Concept Reference

Definition

A concept that describes the set of methods used by the CGAL::Shape_detection::Region_growing to access neighbors of an item.

Has Models:

• CGAL::Shape_detection::Point_set::K_neighbor_query
• CGAL::Shape_detection::Point_set::Sphere_neighbor_query
• CGAL::Shape_detection::Polygon_mesh::Polyline_graph
• CGAL::Shape_detection::Polygon_mesh::One_ring_neighbor_query

Public Types
typedef unspecified_type	Item
	The reference type to the elements of the input range, e.g., a const_iterator of the input range.

Public Member Functions
void	operator() (Item query_index, std::vector< Item > &neighbors)
	fills neighbors with the Items of all items, which are connected to the Item query.

Member Function Documentation

operator()()

void NeighborQuery::operator()	(	Item	query_index,
		std::vector< Item > &	neighbors
	)

fills neighbors with the Items of all items, which are connected to the Item query.

CGAL::Shape_detection::Region_growing calls this function each time when a new query item is selected.
