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.

Compare to a C string.

Parameters

Returns

Integer < 0, 0, or > 0.

Returns an integer < 0 if this string is ordered before __s, 0 if their values are equivalent, or > 0 if this string is ordered after __s.

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

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

Removes the characters in the range [__pos,__pos+__n) from this string. In place, the value of __str is inserted. If __pos is beyond end of string, out_of_range is thrown. If the length of the result exceeds max_size(), length_error is thrown. The value of the string doesn't change if an error is thrown.

Attempt to preallocate enough memory for specified number of characters.

Parameters

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.

Parameters

Exceptions

std::length_error If __res_arg exceeds max_size().

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.
