2005-07-05 Paolo Carlini <pcarlini@suse.de> Add class __versa_string, a versatile "basic_string-type" class: an additional, non-standard, template parameter allows to specify the preferred base class.

|
||||
*
|
||||
* @code
|
||||
* [_Rep]
|
||||
* _M_length
|
||||
* [__rc_string_base<char_type>] _M_capacity
|
||||
* _M_dataplus _M_refcount
|
||||
* _M_p ----------------> unnamed array of char_type
|
||||
* @endcode
|
||||
*
|
||||
* 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_refdata(), and
|
||||
* __rc_string_base::_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 C++ string implementation.
