Detailed Description

A Logger instance works as debugging API to send formatted strings to its current listener instance via the EGLOG()-macro.

Constructor & Destructor Documentation

Logger()

Logger

(

int

debugLevel = DebugLevel::WARNINGS

)

Constructor: Creates a new Logger instance and sets the initial debug level.

Parameters

debugLevel

the minimum debug level that a message must have to actually get logged by this Logger instance (the default is DebugLevel::WARNINGS)

Member Function Documentation

log()

void log	(	int	debugLevel,
		const EG_CHAR *	file,
		const EG_CHAR *	function,
		bool	printBrackets,
		unsigned int	line,
		const EG_CHAR *	dbgMsg,
			...
	)		const

Not intended for direct use - you should use the EGLOG() macro instead!

vlog()

void vlog	(	int	debugLevel,
		const EG_CHAR *	file,
		const EG_CHAR *	function,
		bool	printBrackets,
		unsigned int	line,
		const EG_CHAR *	dbgMsg,
		va_list	args
	)		const

Not intended for direct use - you should use the EGLOG() macro instead!

getDebugOutputLevel()

int getDebugOutputLevel

(

void

)

const

Returns the current level of debug information that's passed on to BaseListener::debugReturn().

Returns

one of the values in DebugLevel

See also

setDebugOutputLevel()

setDebugOutputLevel()

bool setDebugOutputLevel

(

int

debugLevel

)

Sets the current level of debug information that's passed on to BaseListener::debugReturn().

Parameters

debugLevel

one of the values in DebugLevel

Returns

true if the new debug level has been set correctly, false otherwise.

getDebugOutputLevel()

setListener()

void setListener

(

const BaseListener &

listener

)

Sets parameter "listener" as receiver for all debug output information, which gets logged by the Logger instance, on which this function has been called.

Parameters

listener

a reference to an instance of a subclass of BaseListener

Returns

true if the new debug level has been set correctly, false otherwise.

getDebugOutputLevel()

getFormatOptions()

const LogFormatOptions & getFormatOptions

(

void

)

const

Returns

the LogFormatOptions that are used by this instance.

See also

setFormatOptions()

setFormatOptions()

void setFormatOptions

(

const LogFormatOptions &

formatOptions

)

Sets the log format options to the supplied value.

Parameters

formatOptions

the new value to which the log format options will be set

getFormatOptions()

toString()

JString & toString ( Common::JString &  retStr, bool  withTypes = false  ) const

virtual

Remarks

The cost of this function depends a lot on implementation details of the implementing subclasses, but for container classes this function can become quite expensive, if the instance contains huge amounts of data, as its cost for many container class implementations increases disproportionately high to the size of the payload.

Parameters

retStr	reference to a string, to store the return-value in; the information, which is generated by this function, will be attached at the end of any eventually existing previous content of the string
withTypes	set to true, to include type information in the generated string

Returns

a JString representation of the instance and its contents for debugging purposes.

Implements ToString.
