Variant_SwapVisitor()

template<class t_VARIANT >

bslstl::Variant_SwapVisitor< t_VARIANT >::Variant_SwapVisitor ( t_VARIANT *  variant )

inlineexplicit

Create a Variant_SwapVisitor object that, when invoked, will swap the visited alternative with the active alternative of the specified variant.

void bslstl::Variant_SwapVisitor< t_VARIANT >::operator() ( bsl::in_place_index_t< t_INDEX >  , t_TYPE &  value  ) const

inline

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).
