00109 ** CVS/RCS Log:
00110 ** $Log: dcvrcs.h,v $
00111 ** Revision 1.14  2003/06/12 13:30:58  joergr
00112 ** Added static function checkVR().
00113 **
00114 ** Revision 1.13  2002/12/06 12:49:14  joergr
00115 ** Enhanced "print()" function by re-working the implementation and replacing
00116 ** the boolean "showFullData" parameter by a more general integer flag.
00117 ** Added doc++ documentation.
00118 ** Made source code formatting more consistent with other modules/files.
00119 **
00120 ** Revision 1.12  2002/04/25 09:48:10  joergr
00121 ** Removed getOFStringArray() implementation.
00122 **
00123 ** Revision 1.11  2001/09/25 17:19:30  meichel
00124 ** Adapted dcmdata to class OFCondition
00125 **
00126 ** Revision 1.10  2001/06/01 15:48:48  meichel
00127 ** Updated copyright header
00128 **
00129 ** Revision 1.9  2000/03/08 16:26:22  meichel
00130 ** Updated copyright header.
00131 **
00132 ** Revision 1.8  1999/03/31 09:24:57  meichel
00133 ** Updated copyright header in module dcmdata
00134 **
00135 ** Revision 1.7  1998/11/12 16:47:46  meichel
00136 ** Implemented operator= for all classes derived from DcmObject.
00137 **
00138 ** Revision 1.6  1997/09/11 15:13:12  hewett
00139 ** Modified getOFString method arguments by removing a default value
00140 ** for the pos argument.  By requiring the pos argument to be provided
00141 ** ensures that callers realise getOFString only gets one component of
00142 ** a multi-valued string.
00143 **
00144 ** Revision 1.5  1997/08/29 08:32:40  andreas
00145 ** - Added methods getOFString and getOFStringArray for all
00146 **   string VRs. These methods are able to normalise the value, i. e.
00147 **   to remove leading and trailing spaces. This will be done only if
00148 **   it is described in the standard that these spaces are not relevant.
00149 **   These methods do not test the strings for conformance, this means
00150 **   especially that they do not delete spaces where they are not allowed!
00151 **   getOFStringArray returns the string with all its parts separated by \
00152 **   and getOFString returns only one value of the string.
00153 **   CAUTION: Currently getString returns a string with trailing
00154 **   spaces removed (if dcmEnableAutomaticInputDataCorrection == OFTrue) and
00155 **   truncates the original string (since it is not copied!). If you rely on this
00156 **   behaviour please change your application now.
00157 **   Future changes will ensure that getString returns the original
00158 **   string from the DICOM object (NULL terminated) inclusive padding.
00159 **   Currently, if you call getOF... before calling getString without
00160 **   normalisation, you can get the original string read from the DICOM object.
00161 **
00162 ** Revision 1.4  1996/01/09 11:06:17  andreas
00163 ** New Support for Visual C++
00164 ** Correct problems with inconsistent const declarations
00165 **
00166 ** Revision 1.3  1996/01/05 13:23:03  andreas
00167 ** - changed to support new streaming facilities
00168 ** - more cleanups
00169 ** - merged read / write methods for block and file transfer
