 * $Log: contain.inl,v $
 * Revision 1.54  2004/06/01 05:21:38  csoutheren
 * Added conversions between std::string and PString, and vector<PString> and PStringArray
 *
 * Revision 1.53  2004/05/04 11:10:36  rjongbloed
 * Fixed usage of MakeEmpty() with PStringStream.
 *
 * Revision 1.52  2004/04/24 06:27:56  rjongbloed
 * Fixed GCC 3.4.0 warnings about PAssertNULL and improved recoverability on
 *   NULL pointer usage in various bits of code.
 *
 * Revision 1.51  2004/04/18 04:33:36  rjongbloed
 * Changed all operators that return BOOL to return standard type bool. This is primarily
 *   for improved compatibility with std STL usage removing many warnings.
 *
 * Revision 1.50  2004/04/09 03:42:34  csoutheren
 * Removed all usages of "virtual inline" and "inline virtual"
 *
 * Revision 1.49  2004/01/18 13:43:48  rjongbloed
 * Fixed broken PString::MakeEmpty() function and moved implementations to .inl file.
 *
 * Revision 1.48  2002/10/31 05:52:37  robertj
 * Now comprehensively stated that a PString is ALWAYS an 8 bit string as
 *   there are far too many inheerent assumptions every to make it 16 bit.
 *
 * Revision 1.47  2002/10/04 01:47:44  robertj
 * Added various increment and decrement operators to POrdinalKey.
 *
 * Revision 1.46  2002/08/14 00:43:39  robertj
 * Added ability to have fixed maximum length PStringStream's so does not do
 *   unwanted malloc()'s while outputing data.
 *
 * Revision 1.45  2002/02/15 04:29:49  robertj
 * Added PString::Empty() to return the primordial empty string. Saves on a
 *   couple of memory allocations for every empty string ever used.
 *
 * Revision 1.44  2002/01/22 01:03:57  craigs
 * Added operator += and operator + functions to PStringArray and PStringList
 * Added AppendString operator to PStringArray
 *
 * Revision 1.43  2001/02/13 04:39:08  robertj
 * Fixed problem with operator= in container classes. Some containers will
 *   break unless the copy is virtual (eg PStringStream's buffer pointers) so
 *   needed to add a new AssignContents() function to all containers.
 *
 * Revision 1.42  1999/08/22 12:13:42  robertj
 * Fixed warning when using inlines on older GNU compiler
 *
 * Revision 1.41  1999/03/09 03:08:39  robertj
 * Changes for new documentation system
 *
 * Revision 1.40  1998/09/23 06:20:25  robertj
 * Added open source copyright license.
 *
 * Revision 1.39  1997/12/11 10:27:15  robertj
 * Added type correct Contains() function to dictionaries.
 *
 * Revision 1.38  1997/02/14 13:53:58  robertj
 * Major rewrite of sorted list to use sentinel record instead of NULL pointers.
 *
 * Revision 1.37  1996/09/14 12:54:18  robertj
 * Added operator! for !IsEmpty().
 *
 * Revision 1.36  1996/07/15 10:32:49  robertj
 * Fixed bug in sorted list (crash on remove).
 *
 * Revision 1.35  1996/02/08 11:47:57  robertj
 * Moved Contains function from PSet to PHashTable so available for dictionaries.
 * Added caseless compare operator and spaced concatenation operator.
 *
 * Revision 1.34  1996/01/23 13:10:45  robertj
