BloombergLP::bslstl::Variant_SwapVisitor::operator()

Swap the alternative having index (template parameter) t_INDEX in *d_variant_p with the specified value (i.e. the alternative that is being visited). The behavior is undefined unless t_INDEX is the index of the active alternative of *d_variant_p (or, in C++03, the index of an alternative that has the same type as the active alternative).
