所以这里InterfaceClass传入的实际是InterfaceParams中的Z_Construct_UClass_UTestHelloInterface_NoRegister方法执行后所得到的UClass。 同样在Character.gen.cpp中找到该方法定义: 而该方法的实现是在Interface.gen.cpp中: 所以在构造Character的UClass时,实际注入的InterfaceClass是UTestHelloInterface,也就是说实际上我们Ch...
In Java, you can define an interface as a class with no actual code implementation, but only to define the methods that a class must implement. Those types can be passed as parameters to methods and returned from methods. In C++, a pure virtual class can't be used as a parameter or ...
