Containers of Generic Function Pointers

[inquisitive]

Is there a way to create a collection of Method objects, for example a
vector or a list?

template <typename elemType>
struct Method
{
bool (*function)(ele mType&);

template <typename elemType>
inline bool operator()(elem Type & property)
{
return function(proper ty);
}
};

so that I can do something like:

int main()
{
std::string property;

std::vector <MethodmethodLi st;

Method method;

method.function = someMethod;

methodList.push _back(method);

method.function = someOtherMethod ;

methodList.push _back(method);

std::vector<Met hod>::iterator it;

for(it = methodList.begi n(); it != methodList.end( ); it++)
{
std::cout << "Value: " << ((*it)(property )) << std::endl;
}

return 0;
}

bool someMethod(int & value)
{
value = 25;

return true;
}

bool someOtherMethod (std::string & value)
{
value = "Hello, World!";

return true;
}

You can try boost.function which will be in the next C++ standard:

http://www.boost.org/doc/html/function.html

However, the functions stored need to have the same or a compatible signature.
