constexpr decltype(auto) operator[]( difference_type n ) const   requires ranges::random_access_range<Base>;		(seit C++20)

Gibt das Element an der angegebenen relativen Position nach der Transformation zurück.

Gibt effektiv std::invoke(*parent_->fun_, current_[n]) zurück, wobei *parent_->fun_ die in der übergeordneten transform_view gespeicherte Transformationsfunktion ist und current_ der zugrunde liegende Iterator in V ist.

Parameter

n

-

Position relativ zur aktuellen Position.

Rückgabewert

das transformierte Element
