NAME¶

std::ranges::zip_transform_view::iterator::operator* - std::ranges::zip_transform_view::iterator::operator*

Synopsis¶

constexpr decltype(auto) operator*() const (since C++23)
noexcept(/* see description */);

Returns the transformed element obtained by application of the invocable object of
type F to the underlying poined-to elements.

Equivalent to

return
std::apply
(
[&](auto const&... iters) -> decltype(auto)
{
return std::invoke(*parent_->fun_, *iters...);
},
inner_.current_
);

where *parent_->fun_ is the transformation function stored in the parent
ranges::zip_transform_view, and current_ is the underlying tuple of iterators into
Views....

Parameters¶

(none)

Return value¶

The element which is the result of transformation (mapping).

Exceptions¶

noexcept specification:
noexcept(std::invoke(*parent_->fun_, *std::get<INTS>(inner_.current_)...))

where INTS is the pack of integers 0, 1, ..., (sizeof...(Views)-1).

Notes¶

operator-> is not provided.

The behavior is undefined if the parent_ pointer to parent
ranges::zip_transform_view is null (e.g. if *this is default constructed).
