請幫忙解答，十分謝謝。下面的C++代碼的宏定義是什麼意思?

#define DYNOBJECT_IMPLEMENT_DYNAMIC(name, parent, code)              \
    name::name(const char* b) : parent(#parent, b)                                             \
    {                                                                                                                                  \
        init();                                                                                                                     \
    }                                                                                                                                \
                                                                                                                                      \
    FDynObject* name::prototype(const char* b) const                                      \
    {                                                                                                                               \
        return new name(b);                                                                                      \
    }                                                                                                                             \
                                                                                                                                   \
    void name::objectName(char* b) const                                                          \
    {                                                                                                                               \
        strcpy (b, #name);                                                                                           \
        parent::objectName(b);                                                                                  \
    }                                                                                                                              \
                                                                                                                                  \
