template<typename _CharT, typename _Traits, typename _Alloc>¶

class std::basic_string< _CharT, _Traits, _Alloc >"Managing sequences of characters and character-like objects.

Template Parameters

Meets the requirements of a container, a reversible container, and a sequence. Of the optional sequence requirements, only push_back, at, and array access are supported.

Todo

Documentation? What's that? Nathan Myers ncm@cantrip.org.

A string looks like this:

                                     [_Rep]


                                     _M_length
[basic_string<char_type>]            _M_capacity
_M_dataplus                          _M_refcount
_M_p ---------------->               unnamed array of char_type

Where the _M_p points to the first character in the string, and you cast it to a pointer-to-_Rep and subtract 1 to get a pointer to the header.

This approach has the enormous advantage that a string object requires only one allocation. All the ugliness is confined within a single pair of inline functions, which each compile to a single add instruction: _Rep::_M_data(), and string::_M_rep(); and the allocation function which gets a block of raw bytes and with room enough and constructs a _Rep object at the front.

The reason you want _M_data pointing to the character array and not the _Rep is so that the debugger can see the string contents. (Probably we should add a non-inline member to get the _Rep for the debugger to use, so users can check the actual string length.)

Note that the _Rep object is a POD so that you can have a static empty string _Rep object already constructed before static constructors have run. The reference-count encoding is chosen so that a 0 indicates one reference, so you never try to destroy the empty-string _Rep object.

All but the last paragraph is considered pretty conventional for a Copy-On-Write C++ string implementation.

Parameters

Returns

Parameters

Returns

Form the substring of this string from the __n characters starting at __pos. Returns an integer < 0 if the substring is ordered before __str, 0 if their values are equivalent, or > 0 if the substring is ordered after __str. Determines the effective length rlen of the strings to compare as the smallest of the length of the substring and __str.size().

Parameters

Returns

Form the substring of this string from the __n1 characters starting at pos. Returns an integer < 0 if the substring is ordered before __s, 0 if their values are equivalent, or > 0 if the substring is ordered after __s. Determines the effective length rlen of the strings to compare as the smallest of the length of the substring and the length of a string constructed from __s.

Compare substring against a character array.

Parameters

Returns

Form the substring of this string from the __n1 characters starting at __pos. Form a string from the first __n2 characters of __s. Returns an integer < 0 if this substring is ordered before the string from __s, 0 if their values are equivalent, or > 0 if this substring is ordered after the string from __s. Determines the effective length rlen of the strings to compare as the smallest of the length of the substring and __n2.

Parameters

Returns

Form the substring of this string from the __n1 characters starting at __pos1. Form the substring of __str from the __n2 characters starting at __pos2.

template<typename _CharT , typename _Traits , typename _Alloc > void std::basic_string< _CharT, _Traits, _Alloc >::reserve (size_type __res_arg)¶

Attempt to preallocate enough memory for specified number of characters.

Parameters

Exceptions

This function attempts to reserve enough memory for the string to hold the specified number of characters. If the number requested is more than max_size(), length_error is thrown.

The advantage of this function is that if optimal code is a necessity and the user can determine the string length that will be required, the user can reserve the memory in advance, and thus prevent a possible reallocation of memory and copying of string data.

template<typename _CharT , typename _Traits , typename _Alloc > void std::basic_string< _CharT, _Traits, _Alloc >::resize (size_type __n) [inline]¶

Resizes the string to the specified number of characters.

Parameters

This function will resize the string to the specified length. If the new size is smaller than the string's current size the string is truncated, otherwise the string is extended and new characters are default-constructed. For basic types such as char, this means setting them to 0.
