Public Member Functions
	GmTimeMsg (const GmLogCategory &logger, QString msg)

qint64	elapsed () const
	Returns the elapsed tim so far in ms.

Static Public Member Functions
static QString	formatTime (double time, QString unit, bool useConstSizeUnit=false)
	Returns a string representation for the given time in the best possible unit.

static QString	formatTime (double time, int unitIndex, bool useConstSizeUnit=false)
	Returns a string representation for the given time in the best possible unit, with the src unit definied by its index in _timeUnits.

static int	unitIndex (QString unit)
	Returns the index of the unit in the format time table of known units, or -1 if not found.

static QString	indexFmtUnit (int unitIndex)
	Returns the formatted unit (always with 3 characters) for the given unit index returned bu unitIndex()

Private Attributes
QElapsedTimer	_timer
	Timer used to measure elapsed time.

const GmLogCategory &	_logger
	The logger used to emmit messages.

QString	_msg
	Message title.

Static Private Attributes
static int	_nestLevel = 0
	A global value storing the current nesting level (GmTimeMsg objects created in the scope of another one)

static const QStringList	_timeUnits = { "ms", "s", "min", "h", "day" }
	The vector with the conversion "stair" for time conversion.

static const QStringList	_fmtTimeUnits = { "ms ", "s ", "min", "h ", "day" }
	Equivalent to _timeUnits but with formatted strings.

static const QVector< double >	_timeFactors = { 1000, 60, 60, 24, 1 }
	The vector with factors to convert time values between the considered time units.

static const int	_secondIndex = 1
	The index for the second entry in _timeUnits.

Detailed Description

RAII object used to measure the elapsed time of an operation.

When the object is constructed, a timer is started. On destruction, the elapsed time is measured and a message is printed with gmTimeMsg().
