New subject: Boost::Function: Getting a pointer to a template function

27 Feb 2008


      Hi! I want to use a boost::function pointer to a template function. The
template type should be determinated at the time the boost::function
object is initialized. Example:

template<class T>
inline string addNumber(T inputNumber)
{
    return lexical_cast<string>(inputNumber + 2);
}

template<class numType>
inline boost::function getFunction(numType number)
{
    boost::function f;
    f = //Which code can I use here? If I call f() I want to call
addNumber<numType>(number)
}

----------------------
I want to use it like that:

void callFunction()
{
boost::function f;
f = getFunction<unsigned long>();
for(int i = 0; i < 10000;i++)
{
 std::cout << f(rand()) << endl;
}
}

Thanks in advance, Hans
