I've been writing a simple class cFlags, which is meant for storing boolean flags in single variables, as opposed to creating multiple bools (all of which take one byte of memory). Everything is working well, but I've come across this problem while trying to simplify setting flag values. Skipping the irrelevant parts my code looks like this:
template <typename T>
cFlags
{
public:
bool get(char flag);
void set(char flag, bool value);
private:
T flags_;
};
A created class holds a member variable of template type and allows to manage its bits with set() and get() methods (char arguments correspond to specific bits in the flags_ member).
Now, I came up with an idea that I should make an operator[] overload to make setting and getting flag values easier. The problem is, I couldn't find a way to make things like
cFlags<char> flags;
flags[0] = true;
possible, as the operator[] overload only returns an r-value bool that corresponds to whether a bit is lit or not. How should I go about implementing such functionality that I can do for example something like this:
cFlags<char> flags;
flags[0] = true;
if (flags[0]) {
std::cout << "Bit 0 is active!";
}
