Detailed Description

template<typename _CharT, typename _Traits, typename _Alloc>
class std::basic_string< _CharT, _Traits, _Alloc >

Managing sequences of characters and character-like objects.

Template Parameters

_CharT	Type of character
_Traits	Traits for character type, defaults to char_traits<_CharT>.
_Alloc	Allocator type, defaults to allocator<_CharT>.

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:: Needs documentation! See http://gcc.gnu.org/onlinedocs/libstdc++/manual/documentation_style.html

Documentation? What's that? Nathan Myers ncm@c.nosp@m.antr.nosp@m.ip.or.nosp@m.g.

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.

__n1	The number of characters to compare.
__svt	An object convertible to string_view to compare against.
__pos2	A position in the string_view to start comparing from.

◆ compare() [9/9]

template<typename _CharT , typename _Traits , typename _Alloc >

int std::basic_string< _CharT, _Traits, _Alloc >::compare	(	size_type	__pos1,
		size_type	__n1,
		const basic_string< _CharT, _Traits, _Alloc > &	__str,
		size_type	__pos2,
		size_type	__n2 = `npos`
	)		const

Compare substring to a substring.

Parameters

__pos1	Index of first character of substring.
__n1	Number of characters in substring.
__str	String to compare against.
__pos2	Index of first character of substring of str.
__n2	Number of characters in substring of str.

Returns: Integer < 0, 0, or > 0.

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. Returns an integer < 0 if this substring is ordered before the substring of __str, 0 if their values are equivalent, or > 0 if this substring is ordered after the substring of __str. Determines the effective length rlen of the strings to compare as the smallest of the lengths of the substrings. The function then compares the two strings by calling traits::compare(substring.data(),str.substr(pos2,n2).data(),rlen). If the result of the comparison is nonzero returns it, otherwise the shorter one is ordered first.

Parameters

Exceptions

__i1	Iterator referencing start of range to replace.
__i2	Iterator referencing end of range to replace.
__s	C string value to insert.

Returns: Reference to this string.

Exceptions

std::length_error If new length exceeds max_size().

◆ reserve() [2/2]

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

__res_arg Number of characters required.

Exceptions

std::length_error If __res_arg exceeds max_size().

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.

◆ resize() [1/2]

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

__n	Number of characters the string should contain.

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.

__n	Number of characters the string should contain.
__c	Character to fill any new elements.

This function will resize the string to the specified number of characters. If the number is smaller than the string's current size the string is truncated, otherwise the string is extended and new elements are set to __c.
