Returns an iterator or a sentinel that compares equal to the end iterator of the zip_view
Let views_ denote the underlying tuple of views.
- return /*sentinel*/ < false > ( /*tuple-transform*/ ( ranges::end, views_) ) ;
- if /*zip-is-common*/<Views...> evaluates to false
- return begin( ) + std::iter_difference_t < /*iterator*/ < false >> (size( ) ) ;
- if ( ranges::random_access_range <Views> && ...) evaluates to true
- return /*iterator*/ < false > ( /*tuple-transform*/ ( ranges::end, views_) ) ;
- return /*sentinel*/ < true > ( /*tuple-transform*/ ( ranges::end, views_) ) ;
- if /*zip-is-common*/<const Views...> evaluates to false
- return begin( ) + std::iter_difference_t < /*iterator*/ < true >> (size( ) ) ;
- if ranges::random_access_range < const Views> && evaluates to true
- return /*iterator*/ < true > ( /*tuple-transform*/ ( ranges::end, views_) ) ;
Parameters
(none)
Return value
An iterator or sentinel representing the end of the zip_view, as described above.
Notes
ranges::range
<
const
ranges::zip_view
<Views...>>
is modeled if and only if for every type Vi in Views..., const Vi models range
