# UCLASS()
|
|||
|
|
|
|||
|
|
- **功能描述：** 留空的默认行为是不能在蓝图中被继承，不能在蓝图中定义变量，但拥有反射的功能。
|
|||
|
|
|
|||
|
|
- **引擎模块：** UHT
|
|||
|
|
- **元数据类型：** bool
|
|||
|
|
- **作用机制：** 在ClassFlags中增加[CLASS_MatchedSerializers](../../../Flags/EClassFlags/CLASS_MatchedSerializers.md), [CLASS_Native](../../../Flags/EClassFlags/CLASS_Native.md), [CLASS_RequiredAPI](../../../Flags/EClassFlags/CLASS_RequiredAPI.md), [CLASS_TokenStreamAssembled](../../../Flags/EClassFlags/CLASS_TokenStreamAssembled.md), [CLASS_Intrinsic](../../../Flags/EClassFlags/CLASS_Intrinsic.md), [CLASS_Constructed](../../../Flags/EClassFlags/CLASS_Constructed.md)
|
|||
|
|
- **关联项：** [不写UCLASS()](不写UCLASS().md)
|
|||
|
|
- **常用程度：★★★★★**

不能在蓝图中被继承，不能在蓝图中定义变量。
|
|||
|
|
|
|||
|
|
但依然都可以通过蓝图ConstructObject创建出来。对于想要拥有反射功能，但是并不想在蓝图中被使用会挺适合。
|
|||
|
|
|
|||
|
|
## 示例代码：
|
|||
|
|
|
|||
|
|
```cpp
|
|||
|
|
/*
|
|||
|
|
[MyClass_Default Class->Struct->Field->Object /Script/Insider.MyClass_Default] [IncludePath = Class/MyClass_Default.h, ModuleRelativePath = Class/MyClass_Default.h]
|
|||
|
|
ObjectFlags: RF_Public | RF_Standalone | RF_Transient
|
|||
|
|
Outer: Package /Script/Insider
|
|||
|
|
ClassFlags: CLASS_MatchedSerializers | CLASS_Native | CLASS_RequiredAPI | CLASS_TokenStreamAssembled | CLASS_Intrinsic | CLASS_Constructed
|
|||
|
|
Size: 48
|
|||
|
|
{
|
|||
|
|
public: void ExecuteUbergraph(int32 EntryPoint);
|
|||
|
|
};
|
|||
|
|
*/
|
|||
|
|
|
|||
|
|
UCLASS()
|
|||
|
|
class INSIDER_API UMyClass_Default :public UObject
|
|||
|
|
{
|
|||
|
|
GENERATED_BODY()
|
|||
|
|
public:
|
|||
|
|
};
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
默认的拥有这些标志：CLASS_MatchedSerializers | CLASS_Native | CLASS_RequiredAPI | CLASS_TokenStreamAssembled | CLASS_Intrinsic | CLASS_Constructed
|
