I\'m having some problems defining some operator overloads for template classes. Let\'s take this hypothetical class for example.
I have created an enumerated data type to define possible flight lengths. I\'d like to overload its << operator so the representation is nicer.
For example, in the OGRE3D engine, I often see things like开发者_JAVA百科 class_name class_name :: operator + (class_name & object)
I have a filter class wherein the user must declare the type (e.g. Filter<Double>, Filter<Float> etc). The class then implements a moving average filter so objects within the class must be
Is it possible to overload the from/import statement in Python? For example, assuming jvm_object is an instance of class JVM, is it possible to write this code:
I am not sure if I am doing the overload correctly. ...\\point.h(42) : error C2061: syntax error : identifier \'Vec3\'
There are 4 operators in C++ which can be overloaded but cannot be overloaded as freestanding (aka nonmember, standalone) functions. These operators are:开发者_JAVA百科
So, C++ allows overloading the unary operator &(address). Are you aware of any real-world example when operator & was rightfully overloaded? And a second, more specific question, are you aware
class A{ public: virtual char &operator[](int); protected: .. }; class B:A{ public: A* &operator[](int);
struct T { int a; int b; }; class Ptr { public: Ptr(int a, int b) { t_.a = a; t_.b = b; } T* operator->() {retu开发者_开发知识库rn &t_;}
