Exception(char const *file, int line, char const *func, std::string const &message)
Standard constructor, intended for C++ use via the LSST_EXCEPT() macro.
void addMessage(char const *file, int line, char const *func, std::string const &message)
Add a tracepoint and a message to an exception before rethrowing it (access via LSST_EXCEPT_ADD).
virtual std::ostream & addToStream(std::ostream &stream) const
Add a text representation of this exception, including its traceback with messages, to a stream.
virtual Exception * clone(void) const
Return a copy of the exception as an Exception*.
Tracepoint(char const *file, int line, char const *func, std::string const &message)
Standard constructor, intended for C++ use.
Traceback const & getTraceback(void) const
Retrieve the list of tracepoints associated with an exception.
virtual char const * what(void) const
Return a character string summarizing this exception.
std::ostream & operator<<(std::ostream &stream, Exception const &e)
Push the text representation of an exception onto a stream.
virtual char const * getType(void) const
Return the fully-specified C++ type of a pointer to the exception.
One point in the Traceback vector held by Exception.
std::vector< Tracepoint > Traceback
