#define TPSUBCLASSFACTORY_SINGELTON_DEFAULT(factoryClass, parentClass) \
    TPPROTOCOLFACTORY_SINGLETON(factoryClass, parentClass, TPProtocolFactoryDefaultOptions)
```

#define TPSUBCLASSFACTORY_SINGELTON_DEFAULT(factoryClass, parentClass) \
    TPSUBCLASSFACTORY_SINGLETON(factoryClass, parentClass, TPProtocolFactoryDefaultOptions)
```
