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

From cppreference.net

constexpr auto begin ( ) ;	(1)	(C++23以降)
constexpr auto begin ( ) const requires 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)	(C++23以降)

iterator を join_with_view の先頭に返します。

1) 変更可能なイテレータまたはconstイテレータを返す。

V が forward_range をモデル化する場合、以下と等価： constexpr bool use_const =
simple-view < V > && std:: is_reference_v < InnerRng > && simple-view < Pattern > ;
return iterator < use_const > { * this, ranges:: begin ( base_ ) } ; 。
それ以外の場合、以下と等価： outer_it_ = ranges:: begin ( base_ ) ;
return iterator < false > { * this } ; 。

2) constイテレータを返します。


        
         
          concatable

の定義については、 std::ranges::concat_view を参照してください。

1) 上記の通り。


          
           iterator

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


         
          
           base_

) } .
