Hi,
I have a program in C++ with plugins (dynamic libs). In the main program, I want to execute a static function to check if i can create a object of this type.
An example without dynamic libs (aren't neccesary to understand the problem):
#include "libs/parent.h"
#include "libs/one.h"
#include "libs/two.h"
int main(int argc, char * argv[])
{
Parent obj;
if (One.match(argv[1])) {
obj = new One();
else if (Two.match(argv[1])) {
obj = new Two();
}
Now, i have a interface class named Parent. All plugins inherit from this class. Ideally, I have a virtual static function in Parent named match, and all the plugins need to reimplement this function.
The problem with this code is that i can't do a static virtual function in C++, so i don't know how to solve the problem.
Sorry for mi english, i did my best
