Boost.StringView is an implementation of <code class="computeroutput"><span class="identifier">string_view</span></code>
|
||||
as specified in <a href="http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2015/n4480.html#string.view" target="_top">N4480:
|
||||
ISO/IEC DTS 19568, Technical Specification - C++ Extensions for Library Fundamentals</a>.
|
||||
</p>
|
||||
<p>
|
||||
When you are parsing/processing strings from some external source, frequently
|
||||
you want to pass a piece of text to a procedure for specialized processing.
|
||||
The canonical way to do this is as a <code class="computeroutput"><span class="identifier">std</span><span class="special">::</span><span class="identifier">string</span></code>,
|
||||
but that has certain drawbacks:
|
||||
</p>
|
||||
<p>
|
||||
1) If you are processing a buffer of text (say a HTTP response or the contents
|
||||
of a file), then you have to create the string from the text you want to pass,
|
||||
which involves memory allocation and copying of data.
|
||||
</p>
|
||||
<p>
|
||||
2) if a routine receives a constant <code class="computeroutput"><span class="identifier">std</span><span class="special">::</span><span class="identifier">string</span></code>
|
||||
and wants to pass a portion of that string to another routine, then it must
|
||||
create a new string of that substring.
|
||||
</p>
|
||||
<p>
|
||||
3) A routine receives a constant <code class="computeroutput"><span class="identifier">std</span><span class="special">::</span><span class="identifier">string</span></code>
|
||||
and wants to return a portion of the string, then it must create a new string
|
||||
to return.
|
||||
</p>
|
||||
<p>
|
||||
<code class="computeroutput"><span class="identifier">string_view</span></code> is designed to
|
||||
solve these efficiency problems. A <code class="computeroutput"><span class="identifier">string_view</span></code>
|
||||
is a read-only reference to a contiguous sequence of characters, and provides
|
||||
much of the functionality of <code class="computeroutput"><span class="identifier">std</span><span class="special">::</span><span class="identifier">string</span></code>.
|
||||
A <code class="computeroutput"><span class="identifier">string_view</span></code> is cheap to create,
|
||||
copy and pass by value, because it does not actually own the storage that it
|
||||
points to.
|
||||
</p>
|
||||
<p>
|
||||
A <code class="computeroutput"><span class="identifier">string_view</span></code> is implemented
|
||||
as a small struct that contains a pointer to the start of the character data
|
||||
and a count. A <code class="computeroutput"><span class="identifier">string_view</span></code>
|
||||
is cheap to create and cheap to copy.
|
||||
</p>
|
||||
<p>
|
||||
<code class="computeroutput"><span class="identifier">string_view</span></code> acts as a container;
|
||||
it includes all the methods that you would expect in a container, including
|
||||
iteration support, <code class="computeroutput"><span class="keyword">operator</span> <span class="special">[]</span></code>,
|
||||
<code class="computeroutput"><span class="identifier">at</span></code> and <code class="computeroutput"><span class="identifier">size</span></code>.
|
||||
It can be used with any of the iterator-based algorithms in the STL - as long
|
||||
as you don't need to change the underlying data (<code class="computeroutput"><span class="identifier">sort</span></code>
|
||||
and <code class="computeroutput"><span class="identifier">remove</span></code>, for example, will
|
||||
not work)
|
||||
</p>
|
||||
<p>
|
||||
Besides generic container functionality, <code class="computeroutput"><span class="identifier">string_view</span></code>
|
||||
provides a subset of the interface of <code class="computeroutput"><span class="identifier">std</span><span class="special">::</span><span class="identifier">string</span></code>.
|
||||
This makes it easy to replace parameters of type <code class="computeroutput"><span class="keyword">const</span>
|
||||
<span class="identifier">std</span><span class="special">::</span><span class="identifier">string</span> <span class="special">&</span></code>
|
||||
with <code class="computeroutput"><span class="identifier">boost</span><span class="special">::</span><span class="identifier">string_view</span></code>. Like <code class="computeroutput"><span class="identifier">std</span><span class="special">::</span><span class="identifier">string</span></code>,
|
||||
<code class="computeroutput"><span class="identifier">string_view</span></code> has a static member
|
||||
variable named <code class="computeroutput"><span class="identifier">npos</span></code> to denote
|
||||
the result of failed searches, and to mean "the end".
|
||||
</p>
|
||||
<p>
|
||||
Because a <code class="computeroutput"><span class="identifier">string_view</span></code> does
|
||||
not own the data that it "points to", it introduces lifetime issues
|
||||
into code that uses it. The programmer must ensure that the data that a <code class="computeroutput"><span class="identifier">string_view</span></code> refers to exists as long as the
|
||||
<code class="computeroutput"><span class="identifier">string_view</span></code> does.
|
||||
</p>
|
||||
<p>
|
||||
Note: The header actually contains a class template, <code class="computeroutput"><span class="identifier">basic_string_view</span></code>
|
||||
and four typedefs:
|
||||
</p>
|
||||
<pre class="programlisting"><span class="keyword">template</span><span class="special"><</span><span class="keyword">class</span> <span class="identifier">charT</span><span class="special">,</span> <span class="keyword">class</span> <span class="identifier">traits</span> <span class="special">=</span> <span class="identifier">char_traits</span><span class="special"><</span><span class="identifier">charT</span><span class="special">>></span>

|
||||
</pre>
|
||||
<p>
|
||||
So you can have views of strings of any of the four built-in character types
|
||||
as well as strings of user-defined character-like type strings. For the sake
|
||||
of simple exposition, we concentrate on <code class="computeroutput"><span class="identifier">string_view</span></code>
|
||||
(i.e. <code class="computeroutput"><span class="keyword">char</span></code> strings) in this documentation.

<p>
|

Integrating <code class="computeroutput"><span class="identifier">string_view</span></code> into

your code is fairly simple. Wherever you pass a <code class="computeroutput"><span class="keyword">const</span>

|

or <code class="computeroutput"><span class="identifier">std</span><span class="special">::</span><span class="identifier">string</span></code> as a parameter, that's a candidate
|
||||
for passing a <code class="computeroutput"><span class="identifier">boost</span><span class="special">::</span><span class="identifier">string_view</span></code>.

</pre>
|

<p>
|
||||
Let's figure out what happens in this (contrived) example.
|
||||
</p>
|
||||
<p>
|
||||
First, a temporary string is created from the string literal <code class="computeroutput"><span class="string">"ABCDEFG"</span></code>, and it is passed (by reference)
|
||||
to the routine <code class="computeroutput"><span class="identifier">extract_part</span></code>.
|
||||
Then a second string is created in the call <code class="computeroutput"><span class="identifier">std</span><span class="special">::</span><span class="identifier">string</span><span class="special">::</span><span class="identifier">substr</span></code>
|
||||
and returned to <code class="computeroutput"><span class="identifier">extract_part</span></code>
|
||||
(this copy may be elided by RVO). Then <code class="computeroutput"><span class="identifier">extract_part</span></code>
|
||||
returns that string back to the caller (again this copy may be elided). The
|
||||
first temporary string is deallocated, and <code class="computeroutput"><span class="identifier">front</span></code>
|
||||
is called on the second string, and then it is deallocated as well.
|
||||
</p>
|
||||
<p>
|
||||
Two <code class="computeroutput"><span class="identifier">std</span><span class="special">::</span><span class="identifier">string</span></code>s are created, and two copy operations.
|
||||
That's (potentially) four memory allocations and deallocations, and the associated
|
||||
copying of data.
|
||||
</p>
|
||||
<p>
|
||||
Now let's look at the same code with <code class="computeroutput"><span class="identifier">string_view</span></code>:
|
||||
</p>
|
||||
<pre class="programlisting"><span class="identifier">boost</span><span class="special">::</span><span class="identifier">string_view</span> <span class="identifier">extract_part</span> <span class="special">(</span> <span class="identifier">boost</span><span class="special">::</span><span class="identifier">string_view</span> <span class="identifier">bar</span> <span class="special">)</span> <span class="special">{</span>
|
||||
<span class="keyword">return</span> <span class="identifier">bar</span><span class="special">.</span><span class="identifier">substr</span> <span class="special">(</span> <span class="number">2</span><span class="special">,</span> <span class="number">3</span> <span class="special">);</span>
|
||||
<span class="special">}</span>
|
||||
|
||||
<span class="keyword">if</span> <span class="special">(</span> <span class="identifier">extract_part</span> <span class="special">(</span> <span class="string">"ABCDEFG"</span> <span class="special">).</span><span class="identifier">front</span><span class="special">()</span> <span class="special">==</span> <span class="string">"C"</span> <span class="special">)</span> <span class="special">{</span> <span class="comment">/* do something */</span> <span class="special">}</span>
|
||||
</pre>
|
||||
<p>
|
||||
No memory allocations. No copying of character data. No changes to the code
|
||||
other than the types. There are two <code class="computeroutput"><span class="identifier">string_view</span></code>s
|
||||
created, and two <code class="computeroutput"><span class="identifier">string_view</span></code>s
|
||||
copied, but those are cheap operations.

This Boost implementation only requires a C++03 compliant compiler.
|

</p>
|
||||
<p>
|
||||
The actual Library Fundamentals specification assumes a C++14 compliant compiler,
|
||||
so a few features are only present if actually supported by the compiler. Boost
|
||||
macros such as BOOST_CONSTEXPR, BOOST_CXX14_CONSTEXPR, and BOOST_NOEXCEPT supply
|
||||
certain features if supported by the compiler.

[section Overview]
|
||||
[/===============]
|
||||
|
||||
Boost.StringView is an implementation of `string_view` as specified in [@
|
||||
http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2015/n4480.html#string.view N4480:
|
||||
ISO/IEC DTS 19568, Technical Specification - C++ Extensions for Library Fundamentals].
|
||||
|
||||
When you are parsing/processing strings from some external source, frequently you want to pass a piece of text to a procedure for specialized processing. The canonical way to do this is as a `std::string`, but that has certain drawbacks:
|
||||
|
||||
1) If you are processing a buffer of text (say a HTTP response or the contents of a file), then you have to create the string from the text you want to pass, which involves memory allocation and copying of data.
|
||||
|
||||
2) if a routine receives a constant `std::string` and wants to pass a portion of that string to another routine, then it must create a new string of that substring.
|
||||
|
||||
3) A routine receives a constant `std::string` and wants to return a portion of the string, then it must create a new string to return.
|
||||
|
||||
`string_view` is designed to solve these efficiency problems. A `string_view` is a read-only reference to a contiguous sequence of characters, and provides much of the functionality of `std::string`. A `string_view` is cheap to create, copy and pass by value, because it does not actually own the storage that it points to.
|
||||
|
||||
A `string_view` is implemented as a small struct that contains a pointer to the start of the character data and a count. A `string_view` is cheap to create and cheap to copy.
|
||||
|
||||
`string_view` acts as a container; it includes all the methods that you would expect in a container, including iteration support, `operator []`, `at` and `size`. It can be used with any of the iterator-based algorithms in the STL - as long as you don't need to change the underlying data (`sort` and `remove`, for example, will not work)
|
||||
|
||||
Besides generic container functionality, `string_view` provides a subset of the interface of `std::string`. This makes it easy to replace parameters of type `const std::string &` with `boost::string_view`. Like `std::string`, `string_view` has a static member variable named `npos` to denote the result of failed searches, and to mean "the end".
|
||||
|
||||
Because a `string_view` does not own the data that it "points to", it introduces lifetime issues into code that uses it. The programmer must ensure that the data that a `string_view` refers to exists as long as the `string_view` does.
|
||||
|
||||
Note: The header actually contains a class template, `basic_string_view` and four typedefs:
|
||||
|
||||
template<class charT, class traits = char_traits<charT>>
|
||||
class basic_string_view;
|
||||
|
||||
typedef basic_string_view<char> string_view;
|
||||
typedef basic_string_view<char16_t> u16string_view;
|
||||
typedef basic_string_view<char32_t> u32string_view;
|
||||
typedef basic_string_view<wchar_t> wstring_view;
|
||||
|
||||
So you can have views of strings of any of the four built-in character types as well as strings of user-defined character-like type strings. For the sake of simple exposition, we concentrate on `string_view` (i.e. `char` strings) in this documentation.

[section Examples]
|
||||
[/===============]
|
||||
|
||||
Integrating `string_view` into your code is fairly simple. Wherever you pass a `const std::string &` or `std::string` as a parameter, that's a candidate for passing a `boost::string_view`.
|
||||
|
||||
std::string extract_part ( const std::string &bar ) {
|
||||
return bar.substr ( 2, 3 );
|
||||
}
|
||||
|
||||
if ( extract_part ( "ABCDEFG" ).front() == 'C' ) { /* do something */ }
|
||||
|
||||
Let's figure out what happens in this (contrived) example.
|
||||
|
||||
First, a temporary string is created from the string literal `"ABCDEFG"`, and it is passed (by reference) to the routine `extract_part`. Then a second string is created in the call `std::string::substr` and returned to `extract_part` (this copy may be elided by RVO). Then `extract_part` returns that string back to the caller (again this copy may be elided). The first temporary string is deallocated, and `front` is called on the second string, and then it is deallocated as well.
|
||||
|
||||
Two `std::string`s are created, and two copy operations. That's (potentially) four memory allocations and deallocations, and the associated copying of data.
|
||||
|
||||
Now let's look at the same code with `string_view`:
|
||||
|
||||
boost::string_view extract_part ( boost::string_view bar ) {
|
||||
return bar.substr ( 2, 3 );
|
||||
}
|
||||
|
||||
if ( extract_part ( "ABCDEFG" ).front() == "C" ) { /* do something */ }
|
||||
|
||||
No memory allocations. No copying of character data. No changes to the code other than the types. There are two `string_view`s created, and two `string_view`s copied, but those are cheap operations.

[section:reference Reference ]
|
||||
[/=================]
|
||||
|
||||
The header file "string_view.hpp" defines a class template `boost::basic_string_view`, and four specializations - for `char` / `wchar_t` / `char16_t` / `char32_t` .
|
||||
|
||||
`#include <boost/utility/string_view.hpp>`
|
||||
|
||||
Types:
|
||||
|
||||
typedef traits traits_type;
|
||||
typedef charT value_type;
|
||||
typedef charT* pointer;
|
||||
typedef const charT* const_pointer;
|
||||
typedef charT& reference;
|
||||
typedef const charT& const_reference;
|
||||
typedef const_pointer const_iterator; // implementation defined
|
||||
typedef const_iterator iterator;
|
||||
typedef std::reverse_iterator<const_iterator> const_reverse_iterator;
|
||||
typedef const_reverse_iterator reverse_iterator;
|
||||
typedef std::size_t size_type;
|
||||
typedef std::ptrdiff_t difference_type;
|
||||
static BOOST_CONSTEXPR_OR_CONST size_type npos = size_type(-1);
|
||||
|
||||
Construction and copying:
|
||||
|
||||
BOOST_CONSTEXPR basic_string_view () BOOST_NOEXCEPT; // Constructs empty string_view
|
||||
BOOST_CONSTEXPR basic_string_view (const basic_string_view &rhs) BOOST_NOEXCEPT;
|
||||
basic_string_view& operator=(const basic_string_view &rhs) BOOST_NOEXCEPT;
|
||||
template<typename Allocator>
|
||||
basic_string_view(const std::basic_string<charT, traits, Allocator>& str) BOOST_NOEXCEPT; // Ctor from std::string
|
||||
BOOST_CONSTEXPR basic_string_view(const charT* str); // Ctor from NULL-terminated string
|
||||
BOOST_CONSTEXPR basic_string_view(const charT* str, size_type len); // Ctor from pointer, length pair
|
||||
|
||||
`string_view` does not define a move constructor or a move-assignment operator because copying a `string_view` is just as cheap as moving one would be.
|
||||
|
||||
Basic container-like functions:
|
||||
|
||||
BOOST_CONSTEXPR size_type size() const BOOST_NOEXCEPT ;
|
||||
BOOST_CONSTEXPR size_type length() const BOOST_NOEXCEPT ;
|
||||
BOOST_CONSTEXPR size_type max_size() const BOOST_NOEXCEPT ;
|
||||
BOOST_CONSTEXPR bool empty() const BOOST_NOEXCEPT ;
|
||||
|
||||
// All iterators are const_iterators
|
||||
BOOST_CONSTEXPR const_iterator begin() const BOOST_NOEXCEPT ;
|
||||
BOOST_CONSTEXPR const_iterator cbegin() const BOOST_NOEXCEPT ;
|
||||
BOOST_CONSTEXPR const_iterator end() const BOOST_NOEXCEPT ;
|
||||
BOOST_CONSTEXPR const_iterator cend() const BOOST_NOEXCEPT ;
|
||||
const_reverse_iterator rbegin() const BOOST_NOEXCEPT ;
|
||||
const_reverse_iterator crbegin() const BOOST_NOEXCEPT ;
|
||||
const_reverse_iterator rend() const BOOST_NOEXCEPT ;
|
||||
const_reverse_iterator crend() const BOOST_NOEXCEPT ;
|
||||
|
||||
Access to the individual elements (all of which are const):
|
||||
|
||||
BOOST_CONSTEXPR const charT& operator[](size_type pos) const ;
|
||||
BOOST_CONSTEXPR const charT& at(size_t pos) const ;
|
||||
BOOST_CONSTEXPR const charT& front() const ;
|
||||
BOOST_CONSTEXPR const charT& back() const ;
|
||||
BOOST_CONSTEXPR const charT* data() const BOOST_NOEXCEPT ;
|
||||
|
||||
Modifying the `string_view` (but not the underlying data):
|
||||
|
||||
void clear(); // boost extension
|
||||
BOOST_CXX14_CONSTEXPR void remove_prefix(size_type n);
|
||||
BOOST_CXX14_CONSTEXPR void remove_suffix(size_type n);
|
||||
BOOST_CXX14_CONSTEXPR void swap(basic_string_view& s) BOOST_NOEXCEPT;
|
||||
|
||||
Searching:
|
||||
|
||||
BOOST_CXX14_CONSTEXPR size_type find(basic_string_view s, size_type pos = 0) const BOOST_NOEXCEPT;
|
||||
BOOST_CXX14_CONSTEXPR size_type find(charT c, size_type pos = 0) const BOOST_NOEXCEPT;
|
||||
BOOST_CXX14_CONSTEXPR size_type find(const charT* s, size_type pos, size_type n) const;
|
||||
BOOST_CXX14_CONSTEXPR size_type find(const charT* s, size_type pos = 0) const;

BOOST_CXX14_CONSTEXPR size_type rfind(const charT* s, size_type pos, size_type n) const;
|

String-like operations:
|
||||
|
||||
template<class Allocator> // Only present if compiler supports C++11 explicit conversion
|
||||
explicit operator basic_string<charT, traits, Allocator>() const;
|

basic_string<charT, traits, Allocator> // C++11 default template parameters
|

to_string(const Allocator& a = Allocator()) const;
|

size_type copy(charT* s, size_type n, size_type pos = 0) const;

[section Compiler Support]
|
||||
[/===============]
|
||||
|
||||
This Boost implementation only requires a C++03 compliant compiler.
|
||||
|
||||
The actual Library Fundamentals specification assumes a C++14 compliant compiler, so a few features are only present if actually supported by the compiler. Boost macros such as BOOST_CONSTEXPR, BOOST_CXX14_CONSTEXPR, and BOOST_NOEXCEPT supply certain features if supported by the compiler.

// (Matthew Bradbury, fixes #4432)
|

// 07 Aug 08 Added "euclidean" spelling. (Daniel Frey)
|
||||
// 03 Apr 08 Make sure "convertible to bool" is sufficient
|

// for T::operator<, etc. (Daniel Frey)
|
||||
// 24 May 07 Changed empty_base to depend on T, see
|
||||
// http://svn.boost.org/trac/boost/ticket/979
|
||||
// 21 Oct 02 Modified implementation of operators to allow compilers with a
|
||||
// correct named return value optimization (NRVO) to produce optimal
|
||||
// code. (Daniel Frey)
|
||||
// 02 Dec 01 Bug fixed in random_access_iteratable. (Helmut Zeisel)
|
||||
// 28 Sep 01 Factored out iterator operator groups. (Daryle Walker)
|
||||
// 27 Aug 01 'left' form for non commutative operators added;

// additional classes for groups of related operators added;
|
||||
// workaround for empty base class optimization
|
||||
// bug of GCC 3.0 (Helmut Zeisel)

// parameters, added support for self-proxying, additional
|
||||
// documentation and tests (Aleksey Gurtovoy)
|
||||
// 29 May 01 Added operator classes for << and >>. Added input and output
|
||||
// iterator helper classes. Added classes to connect equality and
|
||||
// relational operators. Added classes for groups of related
|
||||
// operators. Reimplemented example operator and iterator helper
|
||||
// classes in terms of the new groups. (Daryle Walker, with help
|

// from Alexy Gurtovoy)
|
||||
// 11 Feb 01 Fixed bugs in the iterator helpers which prevented explicitly

||||
// 12 Nov 99 Add operators templates (Ed Brey)
|
||||
// 11 Nov 99 Add single template parameter version for compilers without
|
||||
// partial specialization (Beman Dawes)
|
||||
// 10 Nov 99 Initial version
|
||||
|
||||
// 10 Jun 00:
|
||||
// An additional optional template parameter was added to most of
|
||||
// operator templates to support the base class chaining technique (see
|
||||
// documentation for the details). Unfortunately, a straightforward
|
||||
// implementation of this change would have broken compatibility with the
|
||||
// previous version of the library by making it impossible to use the same
|
||||
// template name (e.g. 'addable') for both the 1- and 2-argument versions of
|
||||
// an operator template. This implementation solves the backward-compatibility
|
||||
// issue at the cost of some simplicity.
|
||||
//
|
||||
// One of the complications is an existence of special auxiliary class template
|
||||
// 'is_chained_base<>' (see 'detail' namespace below), which is used
|
||||
// to determine whether its template parameter is a library's operator template
|
||||
// or not. You have to specialize 'is_chained_base<>' for each new
|
||||
// operator template you add to the library.
|
||||
//
|
||||
// However, most of the non-trivial implementation details are hidden behind
|
||||
// several local macros defined below, and as soon as you understand them,
|
||||
// you understand the whole library implementation.
