CGAL::tree_point_traits

Definition

tree_point_traits is a template class that provides an interface to data items.

#include <CGAL/Tree_traits.h>


Types

typedef
tree_point_traits<Data, Window, Key, Data_func, Window_left_func, Window_right_func, Compare> Point_traits;

tree_point_traits::Data
the container Data - defines the Data type. It may consist of several data slots. One of these data slots has to be of type Key.


tree_point_traits::Window
the container Window - defines the type of the query rectangle. It may consist of several data slots. Two of these data slots has to be of type Key


tree_point_traits::Key
the type Key of the data slot this traits class provides access to.


tree_point_traits::Data_func
Data_func is a function object providing an operator() that takes an argument of type Data and returns a component of type Key.


tree_point_traits::Window_left_func
Window_left_func is a function objects that allow to access the left data slot of container Window which has type Key


tree_point_traits::Window_right_func
Window_right_func is a function objects that allow to access the right data slot of container Window which has type Key


tree_point_traits::Compare
defines a comparison relation which must define a strict ordering of the objects of type Key. If defined, less<Key> is sufficient.

Creation

tree_point_traits<Data, Window, Key, Data_func, Window_left_func, Window_right_func, Compare> d();
Generation of a tree_point_traits instance. It is a template class that provides an interface to data items.

Operations

Key d.get_key ( Data d)
The data slot of the data item of d of type Key is accessed by function object Data_func.

Key d.get_left ( Window w)
The data slot of the data item of w of type Key is accessed by function object Window_left_func.

Key d.get_right ( Window w)
The data slot of the data item of w of type Key is accessed by function object Window_right_func.

bool d.comp ( Key& key1, Key& key2)
returns Compare(key1, key2).

bool d.key_comp ( Data& data1, Data& data2)
returns Compare(get_key(data1), get_key(data2)).
