std::ranges::transform_view<V,F>::iterator<Const>::operator*
From cppreference.com
< cpp | ranges | transform view | iterator
| constexpr decltype(auto) operator*() const; |
(since C++20) | |
Returns the transformed element.
Effectively returns std::invoke(*parent_->fun_, *current_), where *parent_->fun_ is the transformation function stored in the parent transform_view, and current_ is the underlying iterator into V.
Parameters
(none)
Return value
The transformed element.
Notes
operator-> is not provided.
The behavior is undefined if the pointer to parent transform_view is null (e.g. if *this is default constructed).
If *current_ is a prvalue, its lifetime ends before this function returns. If the transformation function returns a reference or pointer to it, the result would dangle.
