32 Regular expressions are different from many simple pattern-matching algorithms
33 in that as well as finding an overall match they can also produce sub-expression
34 matches: each sub-expression being delimited in the pattern by a pair of
35 parenthesis (...). There has to be some method for reporting sub-expression
36 matches back to the user: this is achieved this by defining a class <a class="link" href="match_results.html" title="match_results"><code class="computeroutput"><span class="identifier">match_results</span></code></a>
37 that acts as an indexed collection of sub-expression matches, each sub-expression
38 match being contained in an object of type <a class="link" href="sub_match.html" title="sub_match"><code class="computeroutput"><span class="identifier">sub_match</span></code></a>.
39 </p>
40 <p>
41 Objects of type <a class="link" href="sub_match.html" title="sub_match"><code class="computeroutput"><span class="identifier">sub_match</span></code></a>
42 may only be obtained by subscripting an object of type <a class="link" href="match_results.html" title="match_results"><code class="computeroutput"><span class="identifier">match_results</span></code></a>.
43 </p>
44 <p>
45 Objects of type <a class="link" href="sub_match.html" title="sub_match"><code class="computeroutput"><span class="identifier">sub_match</span></code></a>
46 may be compared to objects of type <code class="computeroutput"><span class="identifier">std</span><span class="special">::</span><span class="identifier">basic_string</span></code>,
47 or <code class="computeroutput"><span class="keyword">const</span> <span class="identifier">charT</span><span class="special">*</span></code> or <code class="computeroutput"><span class="keyword">const</span>
48 <span class="identifier">charT</span></code>.
49 </p>
50 <p>
51 Objects of type <a class="link" href="sub_match.html" title="sub_match"><code class="computeroutput"><span class="identifier">sub_match</span></code></a>
52 may be added to objects of type <code class="computeroutput"><span class="identifier">std</span><span class="special">::</span><span class="identifier">basic_string</span></code>,
53 or <code class="computeroutput"><span class="keyword">const</span> <span class="identifier">charT</span><span class="special">*</span></code> or <code class="computeroutput"><span class="keyword">const</span>
54 <span class="identifier">charT</span></code>, to produce a new <code class="computeroutput"><span class="identifier">std</span><span class="special">::</span><span class="identifier">basic_string</span></code>
55 object.
56 </p>
57 <p>
58 When the marked sub-expression denoted by an object of type <a class="link" href="sub_match.html" title="sub_match"><code class="computeroutput"><span class="identifier">sub_match</span></code></a> participated in a regular
59 expression match then member <span class="emphasis"><em>matched</em></span> evaluates to <span class="emphasis"><em>true</em></span>,
60 and members <span class="emphasis"><em>first</em></span> and <span class="emphasis"><em>second</em></span> denote
61 the range of characters [first,second) which formed that match. Otherwise
62 <span class="emphasis"><em>matched</em></span> is <span class="emphasis"><em>false</em></span>, and members
63 <span class="emphasis"><em>first</em></span> and <span class="emphasis"><em>second</em></span> contained undefined
64 values.
65 </p>
66 <p>
67 When the marked sub-expression denoted by an object of type <a class="link" href="sub_match.html" title="sub_match"><code class="computeroutput"><span class="identifier">sub_match</span></code></a> was repeated, then the
68 <a class="link" href="sub_match.html" title="sub_match"><code class="computeroutput"><span class="identifier">sub_match</span></code></a>
69 object represents the match obtained by the <span class="emphasis"><em>last</em></span> repeat.
70 The complete set of all the captures obtained for all the repeats, may be
71 accessed via the captures() member function (Note: this has serious performance
72 implications, you have to explicitly enable this feature).
73 </p>
74 <p>
75 If an object of type <a class="link" href="sub_match.html" title="sub_match"><code class="computeroutput"><span class="identifier">sub_match</span></code></a> represents sub-expression
76 0 - that is to say the whole match - then member <span class="emphasis"><em>matched</em></span>
77 is always <span class="emphasis"><em>true</em></span>, unless a <a class="link" href="../partial_matches.html" title="Partial Matches">partial
78 match</a> was obtained as a result of the flag <code class="computeroutput"><span class="identifier">match_partial</span></code>
79 being passed to a regular expression algorithm, in which case member <span class="emphasis"><em>matched</em></span>
80 is <span class="emphasis"><em>false</em></span>, and members <span class="emphasis"><em>first</em></span> and
81 <span class="emphasis"><em>second</em></span> represent the character range that formed the
82 partial match.

410 Defines an implementation-specific type that satisfies the requirements of
411 a standard library Sequence (21.1.1 including the optional Table 68 operations),
412 whose value_type is a <code class="computeroutput"><span class="identifier">sub_match</span><span class="special">&lt;</span><span class="identifier">BidirectionalIterator</span><span class="special">&gt;</span></code>.

420 </p>
421 <p>
422 <span class="bold"><strong>Preconditions</strong></span>: the library must be built
423 and used with BOOST_REGEX_MATCH_EXTRA defined, and you must pass the flag
424 <code class="computeroutput"><span class="identifier">match_extra</span></code> to the regex
425 matching functions ( <a class="link" href="regex_match.html" title="regex_match"><code class="computeroutput"><span class="identifier">regex_match</span></code></a>, <a class="link" href="regex_search.html" title="regex_search"><code class="computeroutput"><span class="identifier">regex_search</span></code></a>, <a class="link" href="regex_iterator.html" title="regex_iterator"><code class="computeroutput"><span class="identifier">regex_iterator</span></code></a> or <a class="link" href="regex_token_iterator.html" title="regex_token_iterator"><code class="computeroutput"><span class="identifier">regex_token_iterator</span></code></a>) in order for

428 <p>
429 <span class="bold"><strong>Rationale</strong></span>: Enabling this feature has several
430 consequences:
431 </p>
432 <div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; ">
433 <li class="listitem">
434 sub_match occupies more memory resulting in complex expressions running
435 out of memory or stack space more quickly during matching.
436 </li>
437 <li class="listitem">
438 The matching algorithms are less efficient at handling some features
439 (independent sub-expressions for example), even when match_extra is not
440 used.
441 </li>
442 <li class="listitem">
443 The matching algorithms are much less efficient (i.e. slower), when match_extra
444 is used. Mostly this is down to the extra memory allocations that have
445 to take place.
