operator== (ranges::join_view:: iterator , ranges::join_view:: iterator )

friend constexpr bool operator == ( const /*iterator*/ & x, const /*iterator*/ & y ) requires /*ref-is-glvalue*/ && std:: equality_comparable < ranges:: iterator_t < Base >> && std:: equality_comparable < ranges:: iterator_t < ranges:: range_reference_t < Base >>> ;		(since C++20)

Compares the underlying iterators.

Equivalent to: return ( x. outer_ == y. outer_ ) and ( x. inner_ == y. inner_ ) ; , where outer_ and inner_ are the underlying iterators. The constant /*ref-is-glvalue*/ in the requires-clause is equal to std:: is_reference_v < ranges:: range_reference_t < Base >> .

The != operator is synthesized from operator== .

This function is not visible to ordinary unqualified or qualified lookup , and can only be found by argument-dependent lookup when std::ranges::join_view:: iterator <Const> is an associated class of the arguments.

Parameters

x, y

-

iterators to compare

Return value

Result of comparison.
