SET_DEFAULT_SUBCLASS

#define SET_DEFAULT_SUBCLASS	(		def,
			set )

Value:

static struct __##set##_DEFAULT_SUBCLASS_REGISTER { \
    __##set##_DEFAULT_SUBCLASS_REGISTER() { \
        __DEFAULT_INSTANTIATORS::get_##def() = []() -> def* { return new set(); }; \
    } \
} __##set##_DEFAULT_SUBCLASS_REGISTER_i;

Registers classes as the default subobject for its class.

Default subobjects are managed by the engine, but custom overrides can be made by inheriting from the base.

Remarks

Call this macro at the top of the source file to set as default

Warning

Trying to set multiple classes as the default for a subclass is undefined behaviour, as the macro utilizes static struct instantiation which is prone to the static initialization order fiasco
