Function Documentation

DECLARE_EXCEPTION	(	ExcXprintfMsg	,
		<< EI_XprintfHeader::val<< EI_XprintfMessage::val
	)

template<class Exc >

EI_Nested make_nested_ei

(

Exc &

e

)

Create EI_Nested error info with given exception.

Used for propagation exception message.

Definition at line 264 of file exceptions.hh.

Here is the caller graph for this function:

template<class Exc >

EI_NestedMessage make_nested_message

(

Exc &

e

)

Propagate just the 'what' message for exceptions that are not derived from ExceptionBase.

Definition at line 277 of file exceptions.hh.

Here is the caller graph for this function:

TYPEDEF_ERR_INFO	(	EI_Nested	,
		std::shared_ptr< ExceptionBase >
	)

Error info of previous exception.

Allows keep and propagate message when one exception is catched and other exception is thrown. Catched exception is stored to EI_Nested and is printed out to message of thrown exception.

Example of usage:

try {
    // method next() throws ExcA
    obj.next();
} catch ( ExcA &e ) {
    // add ExcA to EI tags of ExcB
    THROW( ExcB() << make_nested_ei(e)) );
}

TYPEDEF_ERR_INFO	(	EI_NestedMessage	,
		std::string
	)

TYPEDEF_ERR_INFO	(	EI_XprintfHeader	,
		std::string
	)

Exception thrown in xprintf function.

TYPEDEF_ERR_INFO	(	EI_XprintfMessage	,
		std::string
	)
