One rough idea I had was that since I will always have boost::function
declarations as the default type, I could try to see if the type F is
compatible with the boost::function type? Could this be done in a simple
metafunction similar to the following:
template
struct CheckFunctionCompatible
{
static void Check()
{
F f;
BoostF fboost = f; //If this fails, then I am basically failing
}
};
But then if I instantiate, won't it also try to instantiate the constructor?
template<class F>
class
{
typedef CheckFunctionCompatible, F>
test_F_compatibility;
};
Of course, this wouldn't work for detecting the signature of the function,
but that is a 2nd order feature for me. Of course, this also assumes that F
can be constructed with no parameters, but this also might be reasonable for
me if there is no better solution.
