**
** Revision 1.28  2010-04-23 15:26:12  joergr
** Specify an appropriate default value for the "vm" parameter of checkValue().
**
** Revision 1.27  2010-04-23 14:25:27  joergr
** Added new method to all VR classes which checks whether the stored value
** conforms to the VR definition and to the specified VM.
**
** Revision 1.26  2009-11-04 09:58:07  uli
** Switched to logging mechanism provided by the "new" oflog module
**
** Revision 1.25  2008-07-17 11:19:49  onken
** Updated copyFrom() documentation.
**
** Revision 1.24  2008-07-17 10:30:23  onken
** Implemented copyFrom() method for complete DcmObject class hierarchy, which
** permits setting an instance's value from an existing object. Implemented
** assignment operator where necessary.
**
** Revision 1.23  2006-08-15 15:49:56  meichel
** Updated all code in module dcmdata to correctly compile when
**   all standard C++ classes remain in namespace std.
**
** Revision 1.22  2005/12/08 16:28:53  meichel
** Changed include path schema for all DCMTK header files
**
** Revision 1.21  2004/07/01 12:28:25  meichel
** Introduced virtual clone method for DcmObject and derived classes.
**
** Revision 1.20  2003/06/12 13:31:46  joergr
** Fixed inconsistent API documentation reported by Doxygen.
**
** Revision 1.19  2002/12/06 12:49:14  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 1.18  2002/04/25 09:50:38  joergr
** Added getOFString() implementation.
**
** Revision 1.17  2001/09/25 17:19:30  meichel
** Adapted dcmdata to class OFCondition
**
** Revision 1.16  2001/06/01 15:48:48  meichel
** Updated copyright header
**
** Revision 1.15  2000/04/14 15:31:34  meichel
** Removed default value from output stream passed to print() method.
**   Required for use in multi-thread environments.
**
** Revision 1.14  2000/03/08 16:26:22  meichel
** Updated copyright header.
**
** Revision 1.13  2000/03/03 14:05:26  meichel
** Implemented library support for redirecting error messages into memory
**   instead of printing them to stdout/stderr for GUI applications.
**
** Revision 1.12  2000/02/10 10:50:54  joergr
** Added new feature to dcmdump (enhanced print method of dcmdata): write
** pixel data/item value fields to raw files.
**
** Revision 1.11  1999/03/31 09:24:56  meichel
** Updated copyright header in module dcmdata
**
** Revision 1.10  1998/11/12 16:47:45  meichel
** Implemented operator= for all classes derived from DcmObject.
**
** Revision 1.9  1997/07/21 08:25:13  andreas
** - Replace all boolean types (BOOLEAN, CTNBOOLEAN, DICOM_BOOL, BOOL)
**   with one unique boolean type OFBool.
**
** Revision 1.8  1997/04/18 08:13:29  andreas
** - The put/get-methods for all VRs did not conform to the C++-Standard
**   draft. Some Compilers (e.g. SUN-C++ Compiler, Metroworks
**   CodeWarrier, etc.) create many warnings concerning the hiding of
**   overloaded get methods in all derived classes of DcmElement.
**   So the interface of all value representation classes in the
**   library are changed rapidly, e.g.
**   OFCondition get(Uint16 & value, const unsigned long pos);
**   becomes
**   OFCondition getUint16(Uint16 & value, const unsigned long pos);
**   All (retired) "returntype get(...)" methods are deleted.
**   For more information see dcmdata/include/dcelem.h
**
** Revision 1.7  1996/08/05 08:45:29  andreas
** new print routine with additional parameters:
**         - print into files
**         - fix output length for elements
** corrected error in search routine with parameter ESM_fromStackTop
**
** Revision 1.6  1996/04/16 16:01:37  andreas
** - put methods for AttributeTag with DcmTagKey Parameter
** - better support for NULL values
**
** Revision 1.5  1996/01/29 13:38:15  andreas
** - new put method for every VR to put value as a string
** - better and unique print methods
**
** Revision 1.4  1996/01/09 11:06:17  andreas
** New Support for Visual C++
** Correct problems with inconsistent const declarations
**
** Revision 1.3  1996/01/05 13:23:03  andreas
** - changed to support new streaming facilities
** - more cleanups
** - merged read / write methods for block and file transfer
