Testing private class member in C++ without friend [duplicate]

This question already has an answer here: How do I test a private function or a class that has private methods, fields or inner classes? 51 answers Today I had a discussion with a colleague on whether to test or not to test private members or private state in the class. He almost convinced me why it makes sense. This question does not aim to duplicate already existing StackOverflow questions about the nature and reason of testing private members, like: What is wrong with making a unit test a friend of the class it is testing? Colleagues suggestion was in my opinion a bit fragile to introduce

iOS distribution - parameters in itms-services protocol link for plist

I would like to pass the userid and password in the itms-services link so that the protected plist can be accessed. To clarify, in the following link, the plist cannot be accessed directly as the access requires the userid and password to be entered so that plist is accessible. <a href="itms-services://?action=download-manifest&url=http://example.com/app.plist"> Currently the above link gives an error cannot connect to example.com scooter133 I Was installing the IPA and PLIST on a Windows IIS Server. I had to add MIME types for .ipa and .plist to the IIS Server for the iPad to be able to

Workaround to accomplish protected properties in Objective-C

限于喜欢 提交于 2019-12-02 16:21:53
I've been trying to find a workaround to declare @protected properties in Objective-C so only subclasses in the hierarchy can access them (read only, not write). I read that there is no documented way of doing this so I thought of this workaround and I wanted to ask StackOverflow's opinion about it. Every custom class at the top of the hierarchy contains three classes, one implementation and two interfaces. Let's name them: ClassA.h ClassA_protected.h ClassA.m Then any subclass of this ClassA would be as usual: ClassB.h ClassB.m First I created the interface ClassA.h where I declare a

问题 Consider the following code: #include <iostream> using std::endl; using std::cout; template<typename T> class B{ protected: T value; B* ptr; public: B(T t):value(t), ptr(0){} }; template<typename T> class D: public B<T>{ public: void f(); D(T t):B<T>(t){} }; template<typename T> void D<T>::f(){ cout << this->value << endl; //OK! this->ptr = this; cout << this->ptr->value << endl; //error! cannot access protected member!! B<T>* a = this; cout << a->value <<endl; //error! cannot access

问题 I have a A class in package1 and B is in package2 which inherits A . A contains method m1 which is protected . Now my doubt is when I create an object of B in another class C which is also package2 , the object of B is unable to access method m1 why? Below is my code package com.package1; public class A { protected void m1(){ System.out.println("I'm protectd method of A"); } } package com.package2; import com.package1.A; public class B extends A { public static void main(String[] args) { B b

how to get if array key is protected?

i have this type of array:- i want to get array elemtn. context_course Object ( [_id:protected] => 15 [_contextlevel:protected] => 50 [_instanceid:protected] => 2 [_path:protected] => /1/3/15 [_depth:protected] => 3 ) the problem is [_id:protected] i want to there value 15 how can i get if element is protected . thanks. If a property is protected, it means the developer of the class doesn't want you to be able to freely directly access or modify its value from the public context. If you analyze the class definition for this object, you will most likely find a method that will give you access

Cannot access protected member of another instance from derived type's scope

In this answer to the question " Why can't my object access protected members of another object defined in common base class? ", one can read: You can only access protected members from your own base class instance. Either I don't get it correctly or the following MCVE (live on coliru) proves it wrong: struct Base { void f(); protected: int prot; }; struct Derived : Base { void g(); private: int priv; }; void Base::f() { Base b; b.prot = prot; (void) b; } void Derived::g() { { Derived d; (void) d.priv; } { Derived& d = *this; (void) d.priv; } { Derived d; (void) d.prot; // <-- access to other

I have a class like this : class Foo { public: Foo() { for(int i = 0; i < 10; ++i) v.push_back(i); }; const vector<double>& V() const {return v;}; protected: vector<double>& V() {return v;}; private: vector<double> v; }; And then a piece of code like this : Foo foo; for(int i = 0; i < (int) foo.V().size(); ++i) cout << foo.V().at(i) << endl; However, the latter raises a compilation error saying the V() call is a protected method while i am just trying to read from it, not modify it. I have tried the following (but without success). Foo foo; const vector<double>& test = foo.V(); for(int i = 0;

问题 Admittedly, this question title sounds pretty much exactly the same as the question you neighbour Mike has repeatedly asked. I found quite a few questions worded the same way, but none was what my question is about. First of all, I'd like to clarify a few points for the context of this question: 1, c++ access control works on a class basis rather than instance basis. Therefore, the following code is completely valid. class Base { protected: int b_; public: bool IsEqual(const Base& another)
