// From H5CommonFG.cpp
// Notes with "***Updated" are new and for Group.cpp
// Original notes are from December 2000
//
// There are a few comments that are common to most of the functions
// defined in this file so they are listed here.
// - getLocId is called by all functions, that call a C API, to get
//   the location id, which can be either a file id or a group id.
//   This function is pure virtual and it's up to H5File and Group
//   to call the right getId() - although, as the structure of the
//   library at this time, getId() is basically the IdComponent::getId()
//   ***Updated: after the classes are rearranged (HDFFV-9920), functions
//               in CommonFG are moved to Group, and they can call getId()
//               instead of getLocId().  getLocId() is kept for backward
//               compatibility on user applications.  Aug 18, 2016 -BMR
//   ***Updated: Moving to Group was a mistake, now to H5Location
//               Aug 24, 2016 -BMR
// - when a failure returned by the C API, the functions will call
//   throwException, which is a pure virtual function and is implemented
//   by H5File to throw a FileIException and by Group to throw a
//   GroupIException.
//   ***Updated: after HDFFV-9920, methods in classes H5Location and Group
//   use throwException to distinguish the FileIException and GroupIException.
//   CommonFG is no longer used in the library.  Aug 18, 2016 -BMR
//   H5Location::throwException is changed to throw LocationException for any
//   subclass that is not H5File or Group.  Aug 14, 2017 -BMR
//   ***Note: following the changes in HDFFV-9920, some of the methods could
//   throw different exceptions, but for backward-compatibility, throwException
//   is kept in those methods as well. Sep 17, 2016 -BMR
