DECLARE_CLASS

#define DECLARE_CLASS( TClass, TSuperClass, TStaticFlags, TStaticCastFlags, TPackage, TRequiredAPI  ) \
private: \
    TClass& operator=(TClass&&);   \
    TClass& operator=(const TClass&);   \
	TRequiredAPI static UClass* GetPrivateStaticClass(); \
public: \
	/** Bitwise union of #EClassFlags pertaining to this class.*/ \
	enum {StaticClassFlags=TStaticFlags}; \
	/** Typedef for the base class ({{ typedef-type }}) */ \
	typedef TSuperClass Super;\
	/** Typedef for {{ typedef-type }}. */ \
	typedef TClass ThisClass;\
	/** Returns a UClass object representing this class at runtime */ \
	inline static UClass* StaticClass() \
	{ \
		return GetPrivateStaticClass(); \
	} \
	/** Returns the package this class belongs in */ \
	inline static const TCHAR* StaticPackage() \
	{ \
		return TPackage; \
	} \
	/** Returns the static cast flags for this class */ \
	inline static EClassCastFlags StaticClassCastFlags() \
	{ \
		return TStaticCastFlags; \
	} \
	/** For internal use only; use StaticConstructObject() to create new objects. */ \
	inline void* operator new(const size_t InSize, EInternal InInternalOnly, UObject* InOuter = (UObject*)GetTransientPackage(), FName InName = NAME_None, EObjectFlags InSetFlags = RF_NoFlags) \
	{ \
		return StaticAllocateObject(StaticClass(), InOuter, InName, InSetFlags); \
	} \
	/** For internal use only; use StaticConstructObject() to create new objects. */ \
	inline void* operator new( const size_t InSize, EInternal* InMem ) \
	{ \
		return (void*)InMem; \
	}

首先需要注意的时候这个宏是在UHello类展开的，这里面定义的都是UHello的成员函数。

第一次调用UHello:StaticClass()的时候，会创建一个UClass对象。

具体实现可以看到调用了GetPrivateStaticClass。

通过IMPLEMENT_CLASS在对应的cpp完成了GetPrivateStaticClass的定义。

#define IMPLEMENT_CLASS_NO_AUTO_REGISTRATION(TClass) \
	FClassRegistrationInfo Z_Registration_Info_UClass_##TClass; \
	UClass* TClass::GetPrivateStaticClass() \
	{ \
		if (!Z_Registration_Info_UClass_##TClass.InnerSingleton) \
		{ \
			/* this could be handled with templates, but we want it external to avoid code bloat */ \
			GetPrivateStaticClassBody( \
				StaticPackage(), \
				(TCHAR*)TEXT(#TClass) + 1 + ((StaticClassFlags & CLASS_Deprecated) ? 11 : 0), \
				Z_Registration_Info_UClass_##TClass.InnerSingleton, \
				StaticRegisterNatives##TClass, \
				sizeof(TClass), \
				alignof(TClass), \
				TClass::StaticClassFlags, \
				TClass::StaticClassCastFlags(), \
				TClass::StaticConfigName(), \
				(UClass::ClassConstructorType)InternalConstructor<TClass>, \
				(UClass::ClassVTableHelperCtorCallerType)InternalVTableHelperCtorCaller<TClass>, \
				UOBJECT_CPPCLASS_STATICFUNCTIONS_FORCLASS(TClass), \
				&TClass::Super::StaticClass, \
				&TClass::WithinClass::StaticClass \
			); \
		} \
		return Z_Registration_Info_UClass_##TClass.InnerSingleton; \
	}
  • GetPrivateStaticClassBody里通过placement new创造了一个UClass对象。
  • StaticRegisterNatives##TClass 是nativefun的注册函数，在UClass创造并初始化之后调用。
  • GetPrivateStaticClassBody里传入了InternalConstructor函数指针。InternalConstructor函数包裹了类的构造函数，他作为函数指针存到了对应的UClass中（ClassConstructor）。
/**
 * Helper template to call the default constructor for a class
 */
template<class T>
void InternalConstructor( const FObjectInitializer& X )
{ 
	T::__DefaultConstructor(X);
}

#define DEFINE_DEFAULT_OBJECT_INITIALIZER_CONSTRUCTOR_CALL(TClass) \
	static void __DefaultConstructor(const FObjectInitializer& X) { new((EInternal*)X.GetObj())TClass(X); }

在创建一个新对象时经常会走StaticConstructObject_Internal，从UClass对象中会取出这个构造函数的Wrapper。
