Temporary objects and return by value When a function returns by value, the object that is returned is a temporary object (initialized using the value or object identified in the return statement). Here are some examples: #include<iostream>classIntPair{private:intm_x{};intm_y{};public:IntPai...
A C++ enumeration shape in a class diagram looks and works like a structure shape, except that the label reads Enum or Enum class, it is pink instead of blue, and it has a colored border on the left and top margins. Both enumeration shapes and structure shapes have square corners. Fo...
An object is a typed region of storage in the execution environment; in addition to retaining state information, it also defines behavior. Class-type objects are defined using class-name. Consider the following code fragment: 複製 // class_type_objects.cpp class Account { public: Account() ...

Call the IsKindOf member function for objects of that class, using the RUNTIME_CLASS macro to generate the CRuntimeClass argument, as shown here: 複製 // in .H file class CPerson : public CObject { DECLARE_DYNAMIC( CPerson ) public: CPerson(){}; // other declaration }; // in ....

CFile works in conjunction with the CArchive class to support serialization of Microsoft Foundation Class objects. The hierarchical relationship between this class and its derived classes allows your program to operate on all file objects through the polymorphic CFile interface. A memory file, for ...
全局搜索一下UClassRegisterAllCompiledInClasses()函数,有两个地方: 1. CoreUObject模块的StartupModule()函数内;(定义在CoreNative.cpp源文件中) 2. ProcessNewlyLoadedUObjects(...)函数内;(定义在UObjectBase.cpp源文件中) 自定类UMyObject不属于CoreUObject模块,这里全局搜索一下ProcessNewlyLoadedUObjects函数...
