Feasibility improvement
Description:
- Some member functions in class Exception can be called without
an Exception instance exits, but because they are not static, they
cannot.
- Many exception throwings don't provide any information to callers.
Solution:
- Add 'static' to several member functions in class Exception.
- Added <class name::function name> to some exceptions thrown
in H5File.cpp and H5FcreatProp.cpp. I'm trying this for users'
comments. More information may be added later and to all
exceptions.
- Changed the comment line for emacs editor to:
// C++ informative line for the emacs editor: -*- C++ -*-
because... I'd rather not say that the code "may look like C" :-)
Platforms tested:
Linux (gcc version egcs-2.91.66)

2.5 KiB
