Projection Function Objects

Classes
struct	CGAL::Cast_function_object< Arg, Result >
	The class Cast_function_object applies a C-style type cast to its argument. More...
class	CGAL::Compare_to_less< F >
	The class Compare_to_less is used to convert a functor which returns a Comparison_result to a predicate (returning bool) : it will return true iff the return value of F is SMALLER. More...
struct	CGAL::Dereference< Value >
	The class Dereference dereferences a pointer (operator*). More...
struct	CGAL::Get_address< Value >
	The class Get_address gets the address of an lvalue (operator&). More...
struct	CGAL::Identity< Value >
	The class Identity represents the identity function on Value. More...
struct	CGAL::Project_facet< Node >
	The class Project_facet calls the member function facet() on an instance of type Node. More...
struct	CGAL::Project_next< Node >
	The class Project_next calls the member function next() on an instance of type Node. More...
struct	CGAL::Project_next_opposite< Node >
	The class Project_next_opposite calls the member functions next()->opposite() on an instance of type Node. More...
struct	CGAL::Project_normal< Node >
	The class Project_normal calls the member function normal() on an instance of type Node. More...
struct	CGAL::Project_opposite_prev< Node >
	The class Project_opposite_prev calls the member functions opposite()->prev() on an instance of type Node. More...
struct	CGAL::Project_plane< Node >
	The class Project_plane calls the member function plane() on an instance of type Node. More...
struct	CGAL::Project_point< Node >
	The class Project_point calls the member function point() on an instance of type Node. More...
struct	CGAL::Project_prev< Node >
	The class Project_prev calls the member function prev() on an instance of type Node. More...
struct	CGAL::Project_vertex< Node >
	The class Project_vertex calls the member function vertex() on an instance of type Node. More...

Functions

Compare_to_less< F >	CGAL::compare_to_less (const F &f)
	Changes a functor returning a Comparison_result to one which returns a bool.

compare_to_less()

template<class F >

Compare_to_less< F > CGAL::compare_to_less

(

const F &

f

)

#include <CGAL/function_objects.h>

Changes a functor returning a Comparison_result to one which returns a bool.

The returned functor will return true iff the original one returns SMALLER.

CGAL::Compare_to_less<F>

returns a functor equivalent to f, but which returns a bool instead of a Comparison_result.
