std::experi...tputIterator(3) C++ Standard Libary std::experi...tputIterator(3) NAME std::experimental::ranges::OutputIterator - std::experimental::ranges::Out- putIterator Synopsis Defined in header <experimental/ranges/iterator> template< class I, class T > concept bool OutputIterator = Iterator<I> && Writable<I, T> && requires(I i, T&& t) { (ranges TS) *i++ = std::forward<T>(t); // not required to be equality preserving }; The OutputIterator concept is a refinement of Iterator, adding the re- quirement that it can be used to write values of values of type and value category en- coded by T (via Writable). EqualityComparable is not required. Let E be an expression such that decltype((E)) is T, and i be a derefer- enceable object of type I. OutputIterator<I, T> is satisfied only if *i++ = E; has effects equivalent to *i = E; ++i;. Equality preservation An expression is equality preserving if it results in equal outputs given equal inputs. * The inputs to an expression consist of its operands. * The outputs of an expression consist of its result and all operands modified by the expression (if any). Every expression required to be equality preserving is further required to be stable: two evaluations of such an expression with the same input ob- jects must have equal outputs absent any explicit intervening modification of those in- put objects. Notes Unlike the output iterator requirements in the C++ standard, OutputIter- ator in the Ranges TS does not require that the iterator category tag be defined. Algorithms on output iterators should be single pass. http://cppreference.com 2024.06.10 std::experi...tputIterator(3)
