/*! \class FitsException
@ingroup FITSexcept
@brief FitsException is the base class for all exceptions thrown by this library.
All exceptions derived from this class can be caught by a single 'catch' clause
catching FitsException by reference (which is the point of this base class design).
A static "verboseMode" parameter is provided by the FITS class to
control diagnostics - if FITS::verboseMode() is true, all diagnostics
are printed (for debugging purposes). If not, then a boolean <I>silent</I>
determines printing of messages. Each exception derived from FitsException
must define a default value for the <I>silent</I> parameter.
*/
/*! \fn FitsException::FitsException(const string& diag, bool& silent)
\param diag A diagnostic string to be printed optionally.
\param silent A boolean controlling the printing of messages
*/
/*! \fn const string& FitsException::message () const
\brief returns the error message
This returns the diagnostic error message associated with the
exception object, and which is accessible regardless of the verboseMode
and silent flag settings.
*/
/*! \class FitsError
@ingroup FITSexcept
@brief FitsError is the exception thrown by non-zero cfitsio status codes.
*/
/*! \fn FitsError::FitsError(int errornum, bool silent)
\brief ctor for cfitsio exception: translates status code into cfitsio error message
The exception prefixes the string "Fits Error: " to the message printed by cfitsio.
\param errornum The cfitsio status code produced by the error.
\param silent A boolean controlling the printing of messages
*/
/*! \class FitsFatal
@ingroup FITSexcept
@brief [potential] base class for exceptions to be thrown on internal library error.
As of this version there are no subclasses. This error requests that the
user reports this circumstance to HEASARC.
*/
/*! \fn FitsFatal::FitsFatal(const string& diag)
\brief Prints a message starting "*** CCfits Fatal Error: ..." and calls <i>terminate()</i>
\param diag A diagnostic string to be printed identifying the context of the error.
