An alternative constant _size_constant is provided for use in C++98, for example for declaring arrays. Also renamed underlying_traits to integral_mapping.

// Better Enums makes it easy to iterate over the values you have declared. For
|
|
// example, this:
|
|
|
|
#include <iostream>
|
|
#include <enum.h>
|
|
|
|
ENUM(Channel, int, Red, Green = 2, Blue)
|
|
|
|
int main()
|
|
{
|
|
|
|
for (size_t index = 0; index < Channel::_size(); ++index) {
|
|
Channel channel = Channel::_values()[index];
|
|
std::cout << channel._to_integral() << " ";
|
|
}
|
|
std::cout << std::endl;
|
|
|
|
// will print "0 2 3". And this:
|
|
|
|
for (size_t index = 0; index < Channel::_size(); ++index) {
|
|
const char *name = Channel::_names()[index];
|
|
std::cout << name << " ";
|
|
}
|
|
std::cout << std::endl;
|
|
|
|
// will print "Red Green Blue".
|
|
|
|
// If you are using C++11, you can have much nicer syntax:
|
|
//
|
|
// for (Channel channel : Channel::_values())
|
|
// std::cout << channel._to_integral() << " ";
|
|
// std::cout << std::endl;
|
|
//
|
|
// for (const char *name : Channel::_names())
|
|
// std::cout << name << " ";
|

// std::cout << std::endl;
