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 Pollähne -// - Joe Vitaterna -// - Joe Woodbury -// - Aaron (no last name) -// - Joldakowski (???) -// - Scott Hathaway -// - Eric Nitzche -// - Pablo Presedo -// - Farrokh Nejadlotfi -// - Jason Mills -// - Igor Kholodov -// - Mike Crusader -// - John James -// - Wang Haifeng -// - Tim Dowty -// - Arnt Witteveen -// - Glen Maynard -// - Paul DeMarco -// - Bagira (full name?) -// - Ronny Schulz -// - Jakko Van Hunen -// - Charles G -// -// REVISION HISTORY -// 2003-JUL-10 - Thanks to Charles G for making me realize my 'FmtArg' fixes -// had inadvertently broken the DLL-export code (which is -// normally commented out. I had to move it up higher. Also -// this helped me catch a bug in ssicoll that would prevent -// compilation, otherwise. -// -// 2003-MAR-14 - Thanks to Jakko Van Hunen for pointing out a copy-and-paste -// bug in one of the overloads of FmtArg. -// -// 2003-MAR-10 - Thanks to Ronny Schulz for (twice!) sending me some changes -// to help CStdString build on SGI and for pointing out an -// error in placement of my preprocessor macros for ssfmtmsg. -// -// 2002-NOV-26 - Thanks to Bagira for pointing out that my implementation of -// SpanExcluding was not properly handling the case in which -// the string did NOT contain any of the given characters -// -// 2002-OCT-21 - Many thanks to Paul DeMarco who was invaluable in helping me -// get this code working with Borland's free compiler as well -// as the Dev-C++ compiler (available free at SourceForge). -// -// 2002-SEP-13 - Thanks to Glen Maynard who helped me get rid of some loud -// but harmless warnings that were showing up on g++. Glen -// also pointed out that some pre-declarations of FmtArg<> -// specializations were unnecessary (and no good on G++) -// -// 2002-JUN-26 - Thanks to Arnt Witteveen for pointing out that I was using -// static_cast<> in a place in which I should have been using -// reinterpret_cast<> (the ctor for unsigned char strings). -// That's what happens when I don't unit-test properly! -// Arnt also noticed that CString was silently correcting the -// 'nCount' argument to Left() and Right() where CStdString was -// not (and crashing if it was bad). That is also now fixed! -// -// 2002-FEB-25 - Thanks to Tim Dowty for pointing out (and giving me the fix -// for) a conversion problem with non-ASCII MBCS characters. -// CStdString is now used in my favorite commercial MP3 player! -// -// 2001-DEC-06 - Thanks to Wang Haifeng for spotting a problem in one of the -// assignment operators (for _bstr_t) that would cause compiler -// errors when refcounting protection was turned off. -// -// 2001-NOV-27 - Remove calls to operator!= which involve reverse_iterators -// due to a conflict with the rel_ops operator!=. Thanks to -// John James for pointing this out. -// -// 2001-OCT-29 - Added a minor range checking fix for the Mid function to -// make it as forgiving as CString's version is. Thanks to -// Igor Kholodov for noticing this. -// - Added a specialization of std::swap for CStdString. Thanks -// to Mike Crusader for suggesting this! It's commented out -// because you're not supposed to inject your own code into the -// 'std' namespace. But if you don't care about that, it's -// there if you want it -// - Thanks to Jason Mills for catching a case where CString was -// more forgiving in the Delete() function than I was. -// -// 2001-JUN-06 - I was violating the Standard name lookup rules stated -// in [14.6.2(3)]. None of the compilers I've tried so -// far apparently caught this but HP-UX aCC 3.30 did. The -// fix was to add 'this->' prefixes in many places. -// Thanks to Farrokh Nejadlotfi for this! -// -// 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 a -// 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 Pollähne 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.

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 -// ----------------------------------------------------------------------------- -template -inline int sscpycvt(CT1* pDst, const CT2* pSrc, int nChars) -{ - StdCodeCvt(pDst, pSrc, nChars); - pDst[SSMAX(nChars, 0)] = '\0'; - return nChars; -} - -template -inline int sscpy(CT1* pDst, const CT2* pSrc, int nMax, int nLen) -{ - return sscpycvt(pDst, pSrc, SSMIN(nMax, nLen)); -} -template -inline int sscpy(CT1* pDst, const CT2* pSrc, int nMax) -{ - return sscpycvt(pDst, pSrc, SSMIN(nMax, sslen(pSrc))); -} -template -inline int sscpy(CT1* pDst, const CT2* pSrc) -{ - return sscpycvt(pDst, pSrc, sslen(pSrc)); -} -template -inline int sscpy(CT1* pDst, const std::basic_string& sSrc, int nMax) -{ - return sscpycvt(pDst, sSrc.c_str(), SSMIN(nMax, (int)sSrc.length())); -} -template -inline int sscpy(CT1* pDst, const std::basic_string& sSrc) -{ - return sscpycvt(pDst, sSrc.c_str(), (int)sSrc.length()); -} - -#ifdef SS_INC_COMDEF - template - inline int sscpy(CT1* pDst, const _bstr_t& bs, int nMax) - { - return sscpycvt(pDst, static_cast(bs), - SSMIN(nMax, static_cast(bs.length()))); - } - template - inline int sscpy(CT1* pDst, const _bstr_t& bs) - { - return sscpy(pDst, bs, static_cast(bs.length())); - } -#endif - - -// ----------------------------------------------------------------------------- -// Functional objects for changing case.
