snippet: macros with n 'default arguments'

[Meta]

Code:

#define DO(CLASS, PARENT, BINDING1, BINDING2) \
BINDING1##_default(CLASS, PARENT) \
BINDING2##_default(CLASS, PARENT)

#define _default(CLASS, PARENT) std::cout << "_default\n";
#define replicate_default(CLASS, PARENT) std::cout << "replicate_default\n";
#define lua_default(CLASS, PARENT) std::cout << "lua_default\n";

int main()
{
   DO(Class, NullClass)
   DO(Class, NullClass, replicate)
   DO(Class, NullClass, lua)
   DO(Class, NullClass, lua, replicate)
   return 0;
}

Had an small idea ... maybe somebody can use it, I can!

Code:

#define PROPERTY_(TYPE, NAME, BINDING_OR_OBSERVER1, BINDING_OR_OBSERVER2) \
private:\
    FIELD(private, TYPE, m_##NAME);\
    TYPE get_##NAME() const {\
        return m_##NAME;\
    }\
    void set_##NAME(TYPE value) {\
        m_##NAME = value;\
    }\
BINDING_OR_OBSERVER1##_BINDING_PROPERTY_DEFAULT(TYPE, NAME)\
BINDING_OR_OBSERVER2##_BINDING_PROPERTY_DEFAULT(TYPE, NAME)\
\
NET_PROPERTY(TYPE, NAME, BINDING_OR_OBSERVER1##_OBSERVER_PROPERTY_DEFAULT(TYPE, NAME), BINDING_OR_OBSERVER2##_OBSERVER_PROPERTY_DEFAULT(TYPE, NAME))

#define _BINDING_PROPERTY_DEFAULT(TYPE, NAME)  // nothing
#define lua_BINDING_PROPERTY_DEFAULT(TYPE, NAME) LUA_DEFAULT_PROPERTY(TYPE, NAME)
#define net_BINDING_PROPERTY_DEFAULT(TYPE, NAME)  // nothing

#define _OBSERVER_PROPERTY_DEFAULT(TYPE, NAME)  // nothing
#define lua_OBSERVER_PROPERTY_DEFAULT(TYPE, NAME)  // nothing
#define net_OBSERVER_PROPERTY_DEFAULT(TYPE, NAME) m_observers.push_back(new network_observer<TYPE>());

Some kind of spezialization.
