How to use @value annotation for the enum type in idl file?

[xujonnr]

I wanna to generate the enum code like:

    enum Hello : uint32_t
    {
        aaa = 3,
        bbb = 5
    };

I'm trying to use below example in .idl

    enum Hello
    {
        aaa = 3,
        bbb = 5
    };

and

    enum Hello
    {
        @value(2) aaa,
        @value(5) bbb
    };

but it seems fastddsgen dosen't support them.
So how should I do?
