/*
** CVS/RCS Log:
** $Log: dcvris.h,v $
** Revision 1.15  2005/12/08 16:29:00  meichel
** Changed include path schema for all DCMTK header files
**
** Revision 1.14  2004/07/01 12:28:25  meichel
** Introduced virtual clone method for DcmObject and derived classes.
**
** Revision 1.13  2002/12/06 12:49:16  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 1.12  2002/04/25 09:54:28  joergr
** Removed getOFStringArray() implementation.
**
** Revision 1.11  2001/09/25 17:19:32  meichel
** Adapted dcmdata to class OFCondition
**
** Revision 1.10  2001/06/01 15:48:50  meichel
** Updated copyright header
**
** Revision 1.9  2000/03/08 16:26:24  meichel
** Updated copyright header.
**
** Revision 1.8  1999/03/31 09:25:01  meichel
** Updated copyright header in module dcmdata
**
** Revision 1.7  1998/11/12 16:47:50  meichel
** Implemented operator= for all classes derived from DcmObject.
**
** Revision 1.6  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 1.5  1997/08/29 08:32:42  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 1.4  1997/05/12 07:37:45  andreas
** - new get-Methods for DcmDecimalString: getFloat64 and
**   DcmIntegerString: getSint32
**
** Revision 1.3  1996/01/05 13:23:06  andreas
** - changed to support new streaming facilities
** - more cleanups
** - merged read / write methods for block and file transfer
