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

Managing sequences of characters and character-like objects.

Since

C++98

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

_M_dataplus _M_refcount

_M_p ----------------> unnamed array of char_type

A standard container for storing a fixed size sequence of elements.

Managing sequences of characters and character-like objects.

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.

◆ 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 >

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.
