Question

I’m wondering if it is anyhow possible to partially specialize a templated method behaviour in case one of the template parameter it’s of a certain type.

template<class T>
void Foo(T& parameter)
{
    /* some generic - all types - stuff */

    If(T is int) // this is pseudo-code, typeinfo? Boost?
    {
        /* some specific int processing which might not compile with other types */
    }

    /* again some common stuff */
}

Any suggestion is welcome.
Thanks

If you only want to specialize a part of the function then you simply have to factor out the part of the function with specialized implementations:

template<class T>
void Bar(T &t) {}

void Bar(int &i) {
    /* some specific int processing which might not compile with other types */
}


template<class T>
void Foo(T &t) {
    /* some generic - all types - stuff */

    Bar(t);

    /* again some common stuff */
}
