Salgat/Enum-Iterator

A header only library that provides iterator support for enum and enum class.

Enum-Iterator (EnumIt)

Enum-Iterator (EnumIt) is a header only C++11 library that supports iterators for enum and enum class type. EnumIt requires that the enumeration has no custom values (such as enum sample {VALUE = 1}) and requires knowledge of the last entry in the enumeration.

Example

#include <iostream>
#include <string>

#include "enumit.hpp"

enum class SampleId {
    FIRST,
    SECOND,
    THIRD
};

/*
enum SampleId {
    FIRST,
    SECOND,
    THIRD
};*/

int main() {
    for (auto iter = enumit::Begin<SampleId>(); iter != enumit::End<SampleId>(SampleId::THIRD); ++iter) {
        SampleId entry = *iter;
        std::cout << "Current SampleId: " << static_cast<int>(entry) << std::endl;
    }

    for (auto entry : enumit::Iterate<SampleId>(SampleId::THIRD)) {
        std::cout << "Current SampleId: " << static_cast<int>(entry) << std::endl;
    }

    return 0;
}
