<p><code>std::regex_iterator</code> is a read-only <a href="../concept/ForwardIterator.html" title="cpp/concept/ForwardIterator"><code>ForwardIterator</code></a> that accesses the individual matches of a regular expression within the underlying character sequence.
</p><p>On construction, and on every increment, it calls <span class="t-lc"><a href="regex_search.html" title="cpp/regex/regex search">std::regex_search</a></span> and remembers the result (that is, saves a copy of the value <span class="t-c"><span class="mw-geshi cpp source-cpp"><a href="match_results.html"><span class="kw1731">std::<span class="me2">match_results</span></span></a><span class="sy1"><</span>BidirIt<span class="sy1">></span></span></span>). The first object may be read when the iterator is constructed or when the first dereferencing is done. Otherwise, dereferencing only returns a copy of the most recently obtained regex match.
</p><p>The default-constructed <code>std::regex_iterator</code> is the end-of-sequence iterator. When a valid <code>std::regex_iterator</code> is incremented after reaching the last match (<span class="t-lc"><a href="regex_search.html" title="cpp/regex/regex search">std::regex_search</a></span> returns <span class="t-c"><span class="mw-geshi cpp source-cpp"><span class="kw2">false</span></span></span>), it becomes equal to the end-of-sequence iterator. Dereferencing or incrementing it further invokes undefined behavior.
</p><p>A typical implementation of <code>std::regex_iterator</code> holds the begin and the end iterators for the underlying sequence (two instances of BidirIt), a pointer to the regular expression (<span class="t-c"><span class="mw-geshi cpp source-cpp"><span class="kw4">const</span> regex_type<span class="sy2">*</span></span></span>), the match flags (<span class="t-lc"><a href="match_flag_type.html" title="cpp/regex/match flag type">std::regex_constants::match_flag_type</a></span>), and the current match (<span class="t-c"><span class="mw-geshi cpp source-cpp"><a href="match_results.html"><span class="kw1731">std::<span class="me2">match_results</span></span></a><span class="sy1"><</span>BidirIt<span class="sy1">></span></span></span>).
