Public Attributes
bool	logToConsole
	Should we log to the console?

bool	logToSignal
	Should we emit a signal at each logged message?

FILE *	logFile
	Log file handle if logging to files.

QStringList	internalLogList
	Internal storage for log messages if the user didn't supplied his own target in GmSetStringListLogging()

QStringList *	logList
	If non NULL, log messages will be added to this list. Can point to a user list or to internalLogList.

bool	fileFlush
	Flush at every file write?

bool	showLogger
	Should we show the logger name before each message?

bool	showTid
	Should we show the thread id before each message?

bool	hideRepeatedWarnings
	Should we skip warnings already emitted?

QList< QPair< QString, bool > >	rulesList
	List of rules defining which logging levels are active.

QSet< quint32 >	warningCache
	A cache to store already emitted warning messages when hideRepeatedWarnings is set to true. The stored value is a hash code of the given string. We DON'T store the strings, since the probability of colisions is minimum, the cost of storing every message can be high (imagine a warning that includes a node number and is emmited for every node in a million nodes mesh...) and the result of a collision, that probably will never happend, has minimum impact (the worst that can happend is not showing a warning message)

QMap< QString, QPair< qint64, unsigned > >	timeStatisticsMap
	A map collecting time statistics grouped by the message given to the GmTimeMsg constructor. Each pair contains the cumulative time and the number of times that GmTimeMsg wass called for the given message key.

◆ logMutex

QMutex GmLogContextData::logMutex

A mutex for synchronizing access to the logList, warningCache, lastMemoryMeasure and timeStatisticsMap.

Keep in mind that access to the console and to the logFile don't need to be protected as fprintf() is thread safe in both Windows and GCC (required by POSIX standard)

In princple, this single lock can be split in 4 locks, one for each of the protected variables. This can enhance concurrency but doesn't seems really necessary...

The documentation for this struct was generated from the following file:
