#include <CGAL/Profile_counter.h>
The class Profile_counter provides a way to count the number of times a given line of code is executed during the execution of a program, and print this number at the end of the execution of the program. Such counters can be added at critical places in the code, and at the end of the execution of a program, the count is printed on std::cerr, together with an identification string passed to the constructor. The macro CGAL_PROFILER can be used to conveniently place these counters anywhere. They are disabled by default and activated by the global macro CGAL_PROFILE.
| Profile_counter pc ( std::string s); | |
|
The internal counter is
initialized to 0, and the string s is stored for further printing
by the destructor.
| |
| Profile_counter pc; | |
|
The value of the counter is printed
to std::cerr together with the string.
| |
| void | ++ pc | Increments the internal counter. |
#define CGAL_PROFILER(MSG) If CGAL_PROFILE is not defined, then CGAL_PROFILER is defined to an empty statement. Otherwise, it is defined to static CGAL::Profile_counter tmp(MSG); ++tmp;.
