WebRTTI. RTTI是”Runtime Type Information”的缩写,意思是运行时类型信息,它提供了运行时确定对象类型的方法。 运行时类型检查,在C++层面主要体现在dynamic_cast和typeid,VS … WebThe qobject_cast() function behaves similarly to the standard C++ dynamic_cast(), with the advantages that it doesn't require RTTI support and it works across dynamic library boundaries. It attempts to cast its argument to the pointer type specified in angle-brackets, returning a non-zero pointer if the object is of the correct type (determined ...

WebSep 26, 2024 · So basically we'll do something like this: std::shared_ptr firstSRef = std::make_shared (); libsecond.so. This library contains just one class "second" and it has a dependency on first. This class is the one that evaluates the casting. Dynamic casting works within the code and classes belonging to the same shared library. WebThe dynamic_cast operator guarantees the conversion of a pointer to a base class to a pointer to a derived class, or the conversion of an lvalue referring to a base class to a … WebRTTI的工作原理. 只能将RTTI用于包含虚函数的类层次结构,只有这种类层次结构,才应该将派生对象的地址赋给基类指针。 C++有三个支持RTTI的元素: dynamic_cast运算符:使用一个指向基类的指针来生成一个指向派生类的指针,否则该运算符返回0——空指针 bintan island ferry terminal
