Constructor & Destructor Documentation

◆ Logger() [1/2]

template<typename ... TT>

Logger	(	const char *	filename,
		const TT &...	args
	)

Start logging,.

Parameters

funcName	- name of the finction, often assigned as standard C macro FUNCTION .
name	- specifier of the source, file name for example (to be basenamed).

◆ Logger() [2/2]

template<typename ... TT>

Logger	(	Log &	log,
		const char *	filename,
		const TT &...	args
	)

Start logging,.

Parameters

funcName	- name of the finction, often assigned as standard C macro FUNCTION .
name	- specifier of the source, file name for example (to be basenamed).

Member Function Documentation

◆ debug()

template<typename ... TT>

Logger & debug ( const TT &... args )

inline

Debug information.

Internally, this value is added to LOG_DEBUG.

LOG_DEBUG + 0 - print general debugging information
- LOG_DEBUG + 1 - print names for top-level functions entered
- LOG_DEBUG + 5 - print names for functions entered
- LOG_DEBUG + 5 - include time toOStr
- 10 - save results as files
- 15 - save intermediate results as files
- 20 - dump mass data (eg. coordinates during an image traversal)

◆ deprecating()

template<int L = LOG_NOTICE, typename ... TT>

Logger & deprecating ( const TT &... args )

inline

Feature will be removed. Special type of Logger::note().

See also: Logger::obsolete().

◆ isDebug()

bool isDebug ( level_t l = 0 )

inline

Returns true, if the debug level of the monitor is at least l.

Compares the argument to the threshold of the receiving Log monitor, not to the current level of this logger.

◆ isLevel()

bool isLevel ( level_t l )

inline

Returns true, if the log monitor level is at least l.

Compares the argument to the threshold of the receiving Log monitor, not to the current level of this logger.

◆ obsolete()

template<int L = LOG_WARNING, typename ... TT>

Logger & obsolete ( const TT &... args )

inline

Feature has been removed. Special type of Logger::warn().

See also: Logger::deprecating().

◆ operator<<()

Logger & operator<< ( const std::ostream & sstr )

inline

Send a longer [INFO] preceded with a time stamp.

Direct

◆ pending()

template<int L = LOG_INFO, typename ... TT>

Logger & pending ( const TT &... args )

inline

Report a conditional accept/reject, to be completed next.

This message can be sent for example before continuing a further, confirmative check.

◆ reject()

template<int L = LOG_INFO, typename ... TT>

Logger & reject ( const TT &... args )

inline

Some input has been rejected, for example by a syntax.

This message does not indicate error.

◆ setPrefix()

template<typename ... TT>

void setPrefix	(	const char *	filename,
		const TT &...	args
	)

inlineprotected

Sets a label that starts every line in the log.

\param name - explicitly given classname like "Composite" or __FILE__
\param name - __FILE__

void setPrefixOLD(const char *functionName, const char * name);

Parameters

filename	– as returned by built-in macro FILE
func_name	– as returned by built-in macro FUNCTION

TODO:

Parameters

func_params – optional function and template parameters, formulated by the user.

Start from s2, because dir may contain '.'

◆ startTiming() [1/2]

void startTiming ( )

inline

Send a short [INFO] preceded with a time stamp.

Starts, if global TIMING flag is set and my flag unset.

◆ startTiming() [2/2]

template<typename ... TT>

void startTiming ( const TT &... args )

inline

Starts, if global TIMING flag is set and my flag unset.

◆ unimplemented()

template<int L = LOG_NOTICE, typename ... TT>

Logger & unimplemented ( const TT &... args )

inline

Feature to be done. Special type of Logger::note().

See also: Logger::obsolete().
