Detailed Description

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
_CharTType of character
_TraitsTraits for character type, defaults to char_traits<_CharT>.
_AllocAllocator 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.

_AllocAllocator type, defaults to allocator<_CharT>.

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.
Definition array:103
constexpr basic_string() noexcept(/*conditional */)
Default constructor creates an empty string.

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.

Integer < 0, 0, or > 0.

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. The function then compares the two strings by calling traits::compare(substring.data(),s,rlen). If the result of the comparison is nonzero returns it, otherwise the shorter one is ordered first.

NB: s must have at least n2 characters, '\0' has no special meaning.

This is a pointer to the character sequence held by the string. Modifying the characters in the sequence is allowed.

The standard requires this function to be noexcept but for the Copy-On-Write string implementation it can throw. This function allows modifying the string contents directly, which means we must copy-on-write to unshare it, which requires allocating memory.

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.

basic_string std::basic_string< _CharT, _Traits, _Alloc >::substr ( size_type __pos = 0,

Get a substring.

Parameters
__posIndex of first character (default 0).
__nNumber of characters in substring (default remainder).
Returns
The new string.
Exceptions
std::out_of_rangeIf __pos > size().

Construct and return a new string using the __n characters starting at __pos. If the string is too short, use the remainder of the characters. If __pos is beyond the end of the string, out_of_range is thrown.
