/* These QT_METATYPE_INTERFACE_INIT* macros are used to initialize QMetaTypeInterface instance.
- QT_METATYPE_INTERFACE_INIT(Type) -> It takes Type argument and creates all necessary wrapper functions for the Type,
it detects if QT_NO_DATASTREAM was defined. Probably it is the macro that you want to use.
- QT_METATYPE_INTERFACE_INIT_EMPTY() -> It initializes an empty QMetaTypeInterface instance.
- QT_METATYPE_INTERFACE_INIT_NO_DATASTREAM(Type) -> Temporary workaround for missing auto-detection of data stream
operators. It creates same instance as QT_METATYPE_INTERFACE_INIT(Type) but with null stream operators callbacks.
