\section enum_helper__intro Intro
|
|
|
|
C++ introduce a new enum called scoped enum.
|
|
It is better than legacy C enum because it will not leak name into namespace where it locate,
|
|
and also can specify an underlying type to it to make sure it is stored as specified size.
|
|
However, the shortcoming of it is that it lack bitwise operator comparing with legacy C enum.
|
|
Programmer must implement them for scoped enum one by one.
|
|
It is a hardship and inconvenient.
|
|
This is the reason why I invent this class
|
|
|
|
\section enum_helper__Usage Usage
|
|
|
|
In this namespace, we provide all bitwise functions related to scoped enum type which may be used.
|
|
See YYCC::EnumHelper for more detail (It is more clear to read function annotation than I introduce in there repeatedly).
|
|
|
|
\section enum_helper__why Why not Operator Overload
|
|
|
|
I have try it (and you even can see the relic of it in source code).
|
|
But it need a extra statement written in following to include it, otherwise compiler can not see it.
|
|
|
|
\code
|
|
using namespace YYCC::EnumHelper;
|
|
\endcode
|
|
|
|
Another reason why I do not use this method is that
|
|
this overload strategy may be applied to some type which should not be applied by accient, such as non-scoped enum type.
|
|
So I gave up this solution.
