## CGAL::Creator_4<Arg1, Arg2, Arg3, Arg4, Result>

### Definition

The concept Creator_4<Arg1, Arg2, Arg3, Arg4, Result> defines types and operations for creating objects from four arguments.

#include <CGAL/function_objects.h>

### Requirements

Result defines a corresponding constructor.

Creator_4<Arg1, Arg2, Arg3, Arg4, Result>::argument1_type
| type of first argument.
Creator_4<Arg1, Arg2, Arg3, Arg4, Result>::argument2_type
| type of second argument.
Creator_4<Arg1, Arg2, Arg3, Arg4, Result>::argument3_type
| type of third argument.
Creator_4<Arg1, Arg2, Arg3, Arg4, Result>::argument4_type
| type of 4th argument.
Creator_4<Arg1, Arg2, Arg3, Arg4, Result>::result_type
| type of object to create.

result_type

c.operator() (
| argument_type1 a1, argument_type2 a2, argument_type3 a3, argument_type4 a4)

const

|  | returns result_type(a1, a2, a3, a4).
