     This particular cross-reference situation can be handled in multiple ways.

     Assuming that you can't just let A.h include B.h and B.h include A.h because, when including headers at most once, one will be included always before the other, the simplest solution is just to use forward references:

     A.h

     class B;class A { B* bObj;}

     A.cpp

     #include "A.h"#include "B.h"...

     B.h

     class A;class B { A* aObjM;}

     B.cpp

     #include "B.h"#include "A.h"...

     This simple solution doesn't allow you to use A specifications in B.h (eg calling a method) and vice-versa, nor it allows you to store concrete instances (A vs A*) in the B class but it doesn't sound like your case.

   • how to implement Interfaces in C++?

     Top Answer

     Answered Oct 01, 2019 · 168 votes

     C++ has no built-in concepts of interfaces. You can implement it using abstract classes which contains only pure virtual functions. Since it allows multiple inheritance, you can inherit this class to create another class which will then contain this interface (I mean, object interface :) ) in it.

     An example would be something like this -

     class Interface{public: Interface(){} virtual ~Interface(){} virtual void method1() = 0; // "= 0" part makes this method pure virtual, and // also makes this class abstract. virtual void method2() = 0;};class Concrete : public Interface{private: int myMember;public: Concrete(){} ~Concrete(){} void method1(); void method2();};// Provide implementation for the first methodvoid Concrete::method1(){ // Your implementation}// Provide implementation for the second methodvoid Concrete::method2(){ // Your implementation}int main(void){ Interface *f = new Concrete(); f->method1(); f->method2(); delete f; return 0;}

     Use RAII (resource acquisition is initialization) to define the lock on the mutex. This would allow you to forget about point #2, i.e., you don't need to keep track of return statement to release the lock.

     class Lock {public: Lock () { // acquire the semaphore } ~Lock () { // release the semaphore }}

     Next create objects of this class at the start of your functions, i.e.,

     int f1 (int) { Lock l; // you can now forget about release of this lock // as ~Lock() will take care of it}

     A side advantage of this is that even in the case of exceptions being thrown from f1(), you still don't need to worry about releasing the lock. All stack objects are destroyed before a function exits.

     if you really want a C solution, you could go with macros like:

     #define LOCK lock( &yourglobalsemaphore )#define UNLOCK unlock( &yourglobalsemaphore )-#define LOCKED_FUNCTION_ARG1(TRet, FuncName, TArg1, Arg1Name ) \TRet FuncName( TArg1 Arg1Name ) { \ LOCK; \ TRet ret = FuncName##_Locked( Arg1Name ); \ UNLOCK; \ return ret \} \TRet FuncName##_Locked(TArg1 Arg1Name )#define LOCKED_FUNCTION_ARG2(TRet FuncName, TArg1, Arg1Name, TArg2, Arg2Name) \//...etc

     but you will need 1 macro for every count of arguments (and the function should have a return type).

     example usage:

     LOCKED_FUNCTION_ARG1(int, f1, int, myintarg){ //unchanged code here}

     Define the wrapper like this:

     class SemaphoreWrapper{private: semaphore &sem;public SemaphoreWrapper(semaphore &s) { sem = s; sem.lock(); } ~SemaphoreWrapper() { sem.unlock(); }}

     Then simply create an instance of SemaphoreWrapper within each function:

     void func1(){ SemaphoreWrapper(global_semaphore); ...}

     The constructor and destructor of SemaphoreWrapper will take care of the lock/unlock functionality.
