UHT空文件结果分析

一个空文件

#pragma once

#include "CoreMinimal.h"
#include "UObject/Object.h"
#include "Hello.generated.h"

UCLASS()
class TPSPROJECT_API UHello : public UObject
{
    GENERATED_BODY()
};

‍

#define GENERATED_BODY(...) BODY_MACRO_COMBINE(CURRENT_FILE_ID,_,__LINE__,_GENERATED_BODY);
#define BODY_MACRO_COMBINE_INNER(A,B,C,D) A##B##C##D
#define BODY_MACRO_COMBINE(A,B,C,D) BODY_MACRO_COMBINE_INNER(A,B,C,D)

GENERATED_BODY其实就是把文件名行号这些信息拼到一起。结果如下。

​FID_MonsterFrame_Source_TPSProject_Hello_h_15_GENERATED_BODY​

对这些宏定义的实现往前找，显然在UHT生成的Hello.generated.h中。

文件路径在MonsterFrame\Intermediate\Build\Win64\UnrealEditor\Inc\TPSProject\UHT​

上面文件最开始包含了两个头文件，其中大部分宏定义在ObjectMacro里能找到。

可以看到空类只有后面两个宏有实际的定义。

‍

#define FID_MonsterFrame_Source_TPSProject_Hello_h_15_INCLASS_NO_PURE_DECLS \
private: \
	static void StaticRegisterNativesUHello(); \
	friend struct Z_Construct_UClass_UHello_Statics; \
public: \
	DECLARE_CLASS(UHello, UObject, COMPILED_IN_FLAGS(0), CASTCLASS_None, TEXT("/Script/TPSProject"), NO_API) \
	DECLARE_SERIALIZER(UHello)

#define FID_MonsterFrame_Source_TPSProject_Hello_h_15_ENHANCED_CONSTRUCTORS \
	/** Standard constructor, called after all reflected properties have been initialized */ \
	NO_API UHello(const FObjectInitializer& ObjectInitializer = FObjectInitializer::Get()); \
private: \

	NO_API UHello(UHello&&); \
	NO_API UHello(const UHello&); \
public: \
	DECLARE_VTABLE_PTR_HELPER_CTOR(NO_API, UHello); \
	DEFINE_VTABLE_PTR_HELPER_CTOR_CALLER(UHello); \
	DEFINE_DEFAULT_OBJECT_INITIALIZER_CONSTRUCTOR_CALL(UHello) \
	NO_API virtual ~UHello();

GENERATED_BODY VS GENERATED_UCLASS_BODY

两者的差别很小，GENERATED_BODY中是NO_API UHello(const FObjectInitializer& ObjectInitializer = FObjectInitializer::Get()) : Super(ObjectInitializer) { };

里面多了一个Super(ObjectInitializer) { }，多了一个构造函数的默认实现。

意味着GENERATED_BODY里定义和实现都可以。

GENERATED_UCLASS_BODY里宏展开只有一个定义，所以如果使用GENERATED_UCLASS_BODY的话，需要在CPP中补一个定义

​UHello::UHello(const FObjectInitializer& ObjectInitializer) : Super(ObjectInitializer){}​

‍

这两个宏里主要是一些构造函数和初始化的工作。

  • StaticRegisterNativesUHello 每个UFunction会有一个对应的CFunction，字符串和CFunction的绑定关系在这里生成。有了这个绑定关系，当我们传入字符串的时候，可以查找到对应的CFunction去执行。
  • DECLARE_CLASS[1]：对于每一个UObject，需要定义其Class

‍

‍

‍

展开头文件中构造函数的宏

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

template<class T>
void InternalConstructor( const FObjectInitializer& X )
{ 
	T::__DefaultConstructor(X);
}

这里是一种placementnew写法。

在FObjectInitializer中分配好的指针处构造对象。

后面调用静态函数ClassName::__DefaultConstructor(FObjectInitializer)即可完成构造。

‍

‍

  1. 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。
