00141 ** CVS/RCS Log:
00142 ** $Log: dcvrlt.h,v $
00143 ** Revision 1.20  2010-10-14 13:15:43  joergr
00144 ** Updated copyright header. Added reference to COPYRIGHT file.
00145 **
00146 ** Revision 1.19  2010-04-23 15:26:13  joergr
00147 ** Specify an appropriate default value for the "vm" parameter of checkValue().
00148 **
00149 ** Revision 1.18  2010-04-23 14:25:27  joergr
00150 ** Added new method to all VR classes which checks whether the stored value
00151 ** conforms to the VR definition and to the specified VM.
00152 **
00153 ** Revision 1.17  2010-03-01 09:08:45  uli
00154 ** Removed some unnecessary include directives in the headers.
00155 **
00156 ** Revision 1.16  2009-08-03 09:05:30  joergr
00157 ** Added methods that check whether a given string value conforms to the VR and
00158 ** VM definitions of the DICOM standards.
00159 **
00160 ** Revision 1.15  2008-07-17 11:19:49  onken
00161 ** Updated copyFrom() documentation.
00162 **
00163 ** Revision 1.14  2008-07-17 10:30:23  onken
00164 ** Implemented copyFrom() method for complete DcmObject class hierarchy, which
00165 ** permits setting an instance's value from an existing object. Implemented
00166 ** assignment operator where necessary.
00167 **
00168 ** Revision 1.13  2005-12-08 16:29:02  meichel
00169 ** Changed include path schema for all DCMTK header files
00170 **
00171 ** Revision 1.12  2004/07/01 12:28:25  meichel
00172 ** Introduced virtual clone method for DcmObject and derived classes.
00173 **
00174 ** Revision 1.11  2002/12/06 12:49:17  joergr
00175 ** Enhanced "print()" function by re-working the implementation and replacing
00176 ** the boolean "showFullData" parameter by a more general integer flag.
00177 ** Added doc++ documentation.
00178 ** Made source code formatting more consistent with other modules/files.
00179 **
00180 ** Revision 1.10  2001/09/25 17:19:32  meichel
00181 ** Adapted dcmdata to class OFCondition
00182 **
00183 ** Revision 1.9  2001/06/01 15:48:51  meichel
00184 ** Updated copyright header
00185 **
00186 ** Revision 1.8  2000/03/08 16:26:24  meichel
00187 ** Updated copyright header.
00188 **
00189 ** Revision 1.7  1999/03/31 09:25:03  meichel
00190 ** Updated copyright header in module dcmdata
00191 **
00192 ** Revision 1.6  1998/11/12 16:47:51  meichel
00193 ** Implemented operator= for all classes derived from DcmObject.
00194 **
00195 ** Revision 1.5  1997/09/11 15:13:15  hewett
00196 ** Modified getOFString method arguments by removing a default value
00197 ** for the pos argument.  By requiring the pos argument to be provided
00198 ** ensures that callers realise getOFString only gets one component of
00199 ** a multi-valued string.
00200 **
00201 ** Revision 1.4  1997/08/29 08:32:43  andreas
00202 ** - Added methods getOFString and getOFStringArray for all
00203 **   string VRs. These methods are able to normalise the value, i. e.
00204 **   to remove leading and trailing spaces. This will be done only if
00205 **   it is described in the standard that these spaces are not relevant.
00206 **   These methods do not test the strings for conformance, this means
00207 **   especially that they do not delete spaces where they are not allowed!
00208 **   getOFStringArray returns the string with all its parts separated by \
00209 **   and getOFString returns only one value of the string.
00210 **   CAUTION: Currently getString returns a string with trailing
00211 **   spaces removed (if dcmEnableAutomaticInputDataCorrection == OFTrue) and
00212 **   truncates the original string (since it is not copied!). If you rely on this
00213 **   behaviour please change your application now.
00214 **   Future changes will ensure that getString returns the original
00215 **   string from the DICOM object (NULL terminated) inclusive padding.
00216 **   Currently, if you call getOF... before calling getString without
00217 **   normalisation, you can get the original string read from the DICOM object.
00218 **
00219 ** Revision 1.3  1996/01/05 13:23:07  andreas
00220 ** - changed to support new streaming facilities
00221 ** - more cleanups
00222 ** - merged read / write methods for block and file transfer
