std::regex_iterator::regex_iterator

regex_iterator();
 (1) (since C++11) 
regex_iterator(BidirIt a, BidirIt b,
               const regex_type& re,
               std::regex_constants::match_flag_type m =
                   std::regex_constants::match_default);
 (2) (since C++11) 
regex_iterator(const regex_iterator&);
 (3) (since C++11) 
regex_iterator(BidirIt, BidirIt,
               const regex_type&&,
               std::regex_constants::match_flag_type =
                   std::regex_constants::match_default) = delete;
 (4) (since C++14)

Constructs a new regex_iterator:

1) Default constructor. Constructs an end-of-sequence iterator.
2) Constructs a regex_iterator from the sequence of characters [a, b), the regular expression re, and a flag m that governs matching behavior. This constructor performs an initial call to std::regex_search with this data. If the result of this initial call is false, *this is set to an end-of-sequence iterator.
3) Copies a regex_iterator.
4) The overload 2 is not allowed to be called with a temporary regex, since the returned iterator would be immediately invalidated.

Parameters

a - BidirIt to the beginning of the target character sequence
b - BidirIt to the end of the target character sequence
re - regular expression used to search the target character sequence
m - flags that govern the behavior of re
