Consider this code: namespace foo {} class A { class B { }; friend int foo::bar( B& ); }; namespace foo { int bar( A::B& )
I have two classes, foo and bar. foo.h #includes bar.h and contains a std::vector of pointers to bar objects. At some point during runtime, bar has to access this vector of pointers to other bar obje
I\'ve a set of classes in my namespace and want to group forward declaration in a define.hpp file. I\'ve already achieve this in others projects, here is an example :
For example, class Segment { frie开发者_如何学运维nd bool someFunc( P_Segment p ); }; typedef boost::shared_ptr<Segment> P_Segment;
I\'m really confused with this problem. What I need to do is use some obj-c runtime feature in my project. Here is simple code in my .m file:
Forward declaration of enums in C does not work for me. I searched the internet and Stack Overflow but all of the questions regarding forward declarations of enumerators refer to C++. What do you do f
I have defined two models where each one references the other, like so: class User(models.Model): # ...
I was facing the same error as asked in this question I overcome with this error by solution ofdeclaring class ahead of time in my .h file with the class parameter
Simply put, what are the (or are there any) differences between doing say class MyClassList : list<MyClass> { };
Bounty question: So, these two Foos aren\'t the same thing. Fine. The second form is given in a library. How do I forward-declare it given that I can\'t change it?
