- // FILE: StdString.h
- // AUTHOR: Joe O'Leary (with outside help noted in comments)
- // REMARKS:
- // This header file declares the CStdStr template. This template derives
- // the Standard C++ Library basic_string<> template and add to it the
- // the following conveniences:
- // - The full MFC CString set of functions (including implicit cast)
- // - writing to/reading from COM IStream interfaces
- // - Functional objects for use in STL algorithms
- //
- // From this template, we intstantiate two classes: CStdStringA and
- // CStdStringW. The name "CStdString" is just a #define of one of these,
- // based upone the _UNICODE macro setting
- //
- // This header also declares our own version of the MFC/ATL UNICODE-MBCS
- // conversion macros. Our version looks exactly like the Microsoft's to
- // facilitate portability.
- //
- // NOTE:
- // If you you use this in an MFC or ATL build, you should include either
- // afx.h or atlbase.h first, as appropriate.
- //
- // PEOPLE WHO HAVE CONTRIBUTED TO THIS CLASS:
- //
- // Several people have helped me iron out problems and othewise improve
- // this class. OK, this is a long list but in my own defense, this code
- // has undergone two major rewrites. Many of the improvements became
- // necessary after I rewrote the code as a template. Others helped me
- // improve the CString facade.
- //
- // Anyway, these people are (in chronological order):
- //
- // - Pete the Plumber (???)
- // - Julian Selman
- // - Chris (of Melbsys)
- // - Dave Plummer
- // - John C Sipos
- // - Chris Sells
- // - Nigel Nunn
- // - Fan Xia
- // - Matthew Williams
- // - Carl Engman
- // - Mark Zeren
- // - Craig Watson
- // - Rich Zuris
- // - Karim Ratib
- // - Chris Conti
- // - Baptiste Lepilleur
- // - Greg Pickles
- // - Jim Cline
- // - Jeff Kohn
- // - Todd Heckel
- // - Ullrich Poll鋒ne
- // - Joe Vitaterna
- // - Joe Woodbury
- // - Aaron (no last name)
- // - Joldakowski (???)
- // - Scott Hathaway
- // - Eric Nitzche
- // - Pablo Presedo
- //
- // REVISION HISTORY
- // 2001-APR-27 - StreamLoad was calculating the number of BYTES in one
- // case, not characters. Thanks to Pablo Presedo for this.
- //
- // 2001-FEB-23 - Replace() had a bug which caused infinite loops if the
- // source string was empty. Fixed thanks to Eric Nitzsche.
- //
- // 2001-FEB-23 - Scott Hathaway was a huge help in providing me with the
- // ability to build CStdString on Sun Unix systems. He
- // sent me detailed build reports about what works and what
- // does not. If CStdString compiles on your Unix box, you
- // can thank Scott for it.
- //
- // 2000-DEC-29 - Joldakowski noticed one overload of Insert failed to do
- // range check as CString's does. Now fixed -- thanks!
- //
- // 2000-NOV-07 - Aaron pointed out that I was calling static member
- // functions of char_traits via a temporary. This was not
- // technically wrong, but it was unnecessary and caused
- // problems for poor old buggy VC5. Thanks Aaron!
- //
- // 2000-JUL-11 - Joe Woodbury noted that the CString::Find docs don't match
- // what the CString::Find code really ends up doing. I was
- // trying to match the docs. Now I match the CString code
- // - Joe also caught me truncating strings for GetBuffer() calls
- // when the supplied length was less than the current length.
- //
- // 2000-MAY-25 - Better support for STLPORT's Standard library distribution
- // - Got rid of the NSP macro - it interfered with Koenig lookup
- // - Thanks to Joe Woodbury for catching a TrimLeft() bug that
- // I introduced in January. Empty strings were not getting
- // trimmed
- //
- // 2000-APR-17 - Thanks to Joe Vitaterna for pointing out that ReverseFind
- // is supposed to be a const function.
- //
- // 2000-MAR-07 - Thanks to Ullrich Poll鋒ne for catching a range bug in one
- // of the overloads of assign.
- //
- // 2000-FEB-01 - You can now use CStdString on the Mac with CodeWarrior!
- // Thanks to Todd Heckel for helping out with this.
- //
- // 2000-JAN-23 - Thanks to Jim Cline for pointing out how I could make the
- // Trim() function more efficient.
- // - Thanks to Jeff Kohn for prompting me to find and fix a typo
- // in one of the addition operators that takes _bstr_t.
- // - Got rid of the .CPP file - you only need StdString.h now!
- //
- // 1999-DEC-22 - Thanks to Greg Pickles for helping me identify a problem
- // with my implementation of CStdString::FormatV in which
- // resulting string might not be properly NULL terminated.
- //
- // 1999-DEC-06 - Chris Conti pointed yet another basic_string<> assignment
- // bug that MS has not fixed. CStdString did nothing to fix
- // it either but it does now! The bug was: create a string
- // longer than 31 characters, get a pointer to it (via c_str())
- // and then assign that pointer to the original string object.
- // The resulting string would be empty. Not with CStdString!
- //
- // 1999-OCT-06 - BufferSet was erasing the string even when it was merely
- // supposed to shrink it. Fixed. Thanks to Chris Conti.
- // - Some of the Q172398 fixes were not checking for assignment-
- // to-self. Fixed. Thanks to Baptiste Lepilleur.
- //
- // 1999-AUG-20 - Improved Load() function to be more efficient by using
- // SizeOfResource(). Thanks to Rich Zuris for this.
- // - Corrected resource ID constructor, again thanks to Rich.
- // - Fixed a bug that occurred with UNICODE characters above
- // the first 255 ANSI ones. Thanks to Craig Watson.
- // - Added missing overloads of TrimLeft() and TrimRight().
- // Thanks to Karim Ratib for pointing them out
- //
- // 1999-JUL-21 - Made all calls to GetBuf() with no args check length first.
- //
- // 1999-JUL-10 - Improved MFC/ATL independence of conversion macros
- // - Added SS_NO_REFCOUNT macro to allow you to disable any
- // reference-counting your basic_string<> impl. may do.
- // - Improved ReleaseBuffer() to be as forgiving as CString.
- // Thanks for Fan Xia for helping me find this and to
- // Matthew Williams for pointing it out directly.
- //
- // 1999-JUL-06 - Thanks to Nigel Nunn for catching a very sneaky bug in
- // ToLower/ToUpper. They should call GetBuf() instead of
- // data() in order to ensure the changed string buffer is not
- // reference-counted (in those implementations that refcount).
- //
- // 1999-JUL-01 - Added a true CString facade. Now you can use CStdString as
- // a drop-in replacement for CString. If you find this useful,
- // you can thank Chris Sells for finally convincing me to give
- // in and implement it.
- // - Changed operators << and >> (for MFC CArchive) to serialize
- // EXACTLY as CString's do. So now you can send a CString out
- // to a CArchive and later read it in as a CStdString. I have
- // no idea why you would want to do this but you can.
- //
- // 1999-JUN-21 - Changed the CStdString class into the CStdStr template.
- // - Fixed FormatV() to correctly decrement the loop counter.
- // This was harmless bug but a bug nevertheless. Thanks to
- // Chris (of Melbsys) for pointing it out
- // - Changed Format() to try a normal stack-based array before
- // using to _alloca().
- // - Updated the text conversion macros to properly use code
- // pages and to fit in better in MFC/ATL builds. In other
- // words, I copied Microsoft's conversion stuff again.
- // - Added equivalents of CString::GetBuffer, GetBufferSetLength
- // - new sscpy() replacement of CStdString::CopyString()
- // - a Trim() function that combines TrimRight() and TrimLeft().
- //
- // 1999-MAR-13 - Corrected the "NotSpace" functional object to use _istpace()
- // instead of _isspace() Thanks to Dave Plummer for this.
- //
- // 1999-FEB-26 - Removed errant line (left over from testing) that #defined
- // _MFC_VER. Thanks to John C Sipos for noticing this.
- //
- // 1999-FEB-03 - Fixed a bug in a rarely-used overload of operator+() that
- // caused infinite recursion and stack overflow
- // - Added member functions to simplify the process of
- // persisting CStdStrings to/from DCOM IStream interfaces
- // - Added functional objects (e.g. StdStringLessNoCase) that
- // allow CStdStrings to be used as keys STL map objects with
- // case-insensitive comparison
- // - Added array indexing operators (i.e. operator[]). I
- // originally assumed that these were unnecessary and would be
- // inherited from basic_string. However, without them, Visual
- // C++ complains about ambiguous overloads when you try to use
- // them. Thanks to Julian Selman to pointing this out.
- //
- // 1998-FEB-?? - Added overloads of assign() function to completely account
- // for Q172398 bug. Thanks to "Pete the Plumber" for this
- //

- // SS_USE_FACET macro and why we need it:

- // Since I'm a good little Standard C++ programmer, I use locales. Thus, I
- // need to make use of the use_facet<> template function here. Unfortunately,

- // C++ Library has a non-standard version of use_facet that takes more
- // arguments than the standard dictates. Since I'm trying to write CStdString
- // to work with any version of the Standard library, this presents a problem.
- //
- // The upshot of this is that I can't do 'use_facet' directly. The MS' docs
- // tell me that I have to use a macro, _USE() instead. Since _USE obviously
- // won't be available in other implementations, this means that I have to write
- // my OWN macro -- SS_USE_FACET -- that evaluates either to _USE or to the
- // standard, use_facet.
- //
- // If you are having trouble with the SS_USE_FACET macro, in your implementation
- // of the Standard C++ Library, you can define your own version of SS_USE_FACET.

- // Usually for generic text mapping, we rely on preprocessor macro definitions

- // macro-based generic text mappings because its character types do not get
- // resolved until template processing which comes AFTER macro processing. In
- // other words, UNICODE is of little help to us in the CStdStr template
- //
- // Therefore, to keep the CStdStr declaration simple, we have these inline
- // functions. The template calls them often. Since they are inline (and NOT
- // exported when this is built as a DLL), they will probably be resolved away
- // to nothing.
- //
- // Without these functions, the CStdStr<> template would probably have to broken
- // out into two, almost identical classes. Either that or it would be a huge,
- // convoluted mess, with tons of "if" statements all over the place checking the
- // size of template parameter CT.
- //
- // In several cases, you will see two versions of each function. One version is

- //
- // DESCRIPTION:
- // This function is very much (but not exactly) like strcpy. These
- // overloads simplify copying one C-style string into another by allowing
- // the caller to specify two different types of strings if necessary.
- //
- // The strings must NOT overlap
- //
- // "Character" is expressed in terms of the destination string, not
- // the source. If no 'nMax' argument is supplied, then the number of
- // characters copied will be sslen(pSrc). A NULL terminator will
- // also be added so pDst must actually be big enough to hold nMax+1
- // characters. The return value is the number of characters copied,
- // not including the NULL terminator.
- //
- // PARAMETERS:
- // pSrc - the string to be copied FROM. May be a char based string, an
- // MBCS string (in Win32 builds) or a wide string (wchar_t).
- // pSrc - the string to be copied TO. Also may be either MBCS or wide
- // nMax - the maximum number of characters to be copied into szDest. Note
- // that this is expressed in whatever a "character" means to pDst.
- // If pDst is a wchar_t type string than this will be the maximum
- // number of wchar_ts that my be copied. The pDst string must be
- // large enough to hold least nMaxChars+1 characters.
- // If the caller supplies no argument for nMax this is a signal to
- // the routine to copy all the characters in pSrc, regardless of
- // how long it is.
- //
- // RETURN VALUE: none
