/*
** CVS/RCS Log:
** $Log: dcvrdt.h,v $
** Revision 1.19  2005/12/08 16:28:57  meichel
** Changed include path schema for all DCMTK header files
**
** Revision 1.18  2004/07/01 12:28:25  meichel
** Introduced virtual clone method for DcmObject and derived classes.
**
** Revision 1.17  2004/04/16 12:49:25  joergr
** Restructured code to avoid default parameter values for "complex types" like
** OFString. Required for Sun CC 2.0.1.
**
** Revision 1.16  2004/01/16 14:04:11  joergr
** Introduced new parameter "dateTimeSeparator" in getISOFormattedXXX() methods
** to support ISO 8601 format as required by XML Schema type "dateTime".
**
** Revision 1.15  2002/12/06 12:49:15  joergr
** Enhanced "print()" function by re-working the implementation and replacing
** the boolean "showFullData" parameter by a more general integer flag.
** Added doc++ documentation.
** Made source code formatting more consistent with other modules/files.
**
** Revision 1.14  2002/04/25 09:51:08  joergr
** Removed getOFStringArray() implementation.
**
** Revision 1.13  2002/04/11 12:25:09  joergr
** Enhanced DICOM date, time and date/time classes. Added support for new
** standard date and time functions.
**
** Revision 1.12  2001/10/10 15:17:37  joergr
** Updated comments.
**
** Revision 1.11  2001/10/01 15:01:39  joergr
** Introduced new general purpose functions to get/set person names, date, time
** and date/time.
**
** Revision 1.10  2001/09/25 17:19:31  meichel
** Adapted dcmdata to class OFCondition
**
** Revision 1.9  2001/06/01 15:48:49  meichel
** Updated copyright header
**
** Revision 1.8  2000/03/08 16:26:23  meichel
** Updated copyright header.
**
** Revision 1.7  1999/03/31 09:24:59  meichel
** Updated copyright header in module dcmdata
**
** Revision 1.6  1998/11/12 16:47:48  meichel
** Implemented operator= for all classes derived from DcmObject.
**
** Revision 1.5  1997/09/11 15:13:14  hewett
** Modified getOFString method arguments by removing a default value
** for the pos argument.  By requiring the pos argument to be provided
** ensures that callers realise getOFString only gets one component of
** a multi-valued string.
**
** Revision 1.4  1997/08/29 08:32:41  andreas
** - Added methods getOFString and getOFStringArray for all
**   string VRs. These methods are able to normalise the value, i. e.
**   to remove leading and trailing spaces. This will be done only if
**   it is described in the standard that these spaces are not relevant.
**   These methods do not test the strings for conformance, this means
**   especially that they do not delete spaces where they are not allowed!
**   getOFStringArray returns the string with all its parts separated by \
**   and getOFString returns only one value of the string.
**   CAUTION: Currently getString returns a string with trailing
**   spaces removed (if dcmEnableAutomaticInputDataCorrection == OFTrue) and
**   truncates the original string (since it is not copied!). If you rely on this
**   behaviour please change your application now.
**   Future changes will ensure that getString returns the original
**   string from the DICOM object (NULL terminated) inclusive padding.
**   Currently, if you call getOF... before calling getString without
**   normalisation, you can get the original string read from the DICOM object.
**
** Revision 1.3  1996/01/05 13:23:05  andreas
** - changed to support new streaming facilities
** - more cleanups
** - merged read / write methods for block and file transfer
