std::ranges::join_with_view<V,Pattern>:: begin

From cppreference.net

constexpr auto begin ( ) ;	(1)	(seit C++23)
constexpr auto begin ( ) const erfordert ranges:: forward_range < const V > && ranges:: forward_range < const Pattern > && std:: is_reference_v < ranges:: range_reference_t < const V >> && ranges:: input_range < ranges:: range_reference_t < const V >> && /concatable/ < ranges:: range_reference_t < const V > , const Pattern > ;	(2)	(seit C++23)

Gibt einen Iterator zum Anfang der join_with_view zurück.

1) Gibt einen veränderbaren Iterator oder konstanten Iterator zurück.

Falls V das Konzept forward_range modelliert, äquivalent zu constexpr bool use_const =
simple-view < V > && std:: is_reference_v < InnerRng > && simple-view < Pattern > ;
return iterator < use_const > { * this, ranges:: begin ( base_ ) } ; .
Andernfalls äquivalent zu outer_it_ = ranges:: begin ( base_ ) ;
return iterator < false > { * this } ; .

2) Gibt einen const-Iterator zurück.

Für die Definition von


        
         
          concatable

1) Wie oben beschrieben.


          
           iterator

< true > { * this, ranges:: begin (


         
          
           base_

) } .

Grund: Kein Beispiel

end	gibt einen Iterator oder Sentinel zum Ende zurück (öffentliche Elementfunktion)
ranges::begin (C++20)	gibt einen Iterator zum Anfang eines Bereichs zurück (Anpassungspunktobjekt)
