#define LASS_UTIL_EXCEPTION_PRIVATE_IMPL ( t_exception )

Value:

virtual void doThrowSelf() const { throw *this; }\
        virtual ::std::auto_ptr< ::lass::util::experimental::RemoteExceptionBase > doClone() const \
        { \
            return ::std::auto_ptr< ::lass::util::experimental::RemoteExceptionBase >(new t_exception(*this)); \
        }\

Definition at line 60 of file exception.h.

#define LASS_THROW_EX	(	t_exception,
		s_message		)	`[related]`

Value:

do\
    {\
        ::std::ostringstream lassUtilExceptionImplBuffer;\
        lassUtilExceptionImplBuffer << s_message;\
        throw t_exception(lassUtilExceptionImplBuffer.str(), LASS_PRETTY_FUNCTION);\
    }\
    while (false)

To throw an exception like util::Exception that accepts a message and a location string, you can supply those strings yourself, ore you can use this macro for your convenience.

This macro will fill in the location by itself so that you only have to worry about the message. And as an extra, the message is streamed, so you can use the regular operator<< to concatenate variables in the message.

  int foo = -5;
  if (foo < 0)
  {
      LASS_THROW_EX(util::Exception, "foo '" << foo << "' is less than zero");
  }

#define LASS_THROW ( s_message ) LASS_THROW_EX(::lass::util::Exception, s_message)

LASS_THROW_EX for lass::util::Exception.

LASS_THROW(something) is identical to LASS_THROW_EX(util::Exception, something)

Definition at line 249 of file exception.h.

#define LASS_CATCH_TO_WARNING

Value:

catch (const ::std::exception& error)\
    {\
        std::cerr << "[LASS RUN MSG] UNDEFINED BEHAVIOUR WARNING: Exception caught in "\
            << LASS_PRETTY_FUNCTION << ":\n" << error.what() << std::endl;\
    }\
    catch (...)\
    {\
        std::cerr << "[LASS RUN MSG] UNDEFINED BEHAVIOUR WARNING: Unknown exception caught in "\
            << LASS_PRETTY_FUNCTION << std::endl;\
    }\

catches all exceptions and prints an undefined behaviour warning to std::cerr
