// This file contains the class Profile_counter which is able to keep track
|
|
// of a number, and prints a message in the destructor.
|
|
// Typically, it can be used as a profile counter in a static variable.
|
|
|
|
// It also provides the class Profile_histogram_counter which is similar,
|
|
// but the counter is indexed by a value (unsigned int), and the final dump
|
|
// is the histogram of the non-zero counters. [TODO : to be documented]
