Constructor & Destructor Documentation

◆ TScaler() [1/4]

TScaler::TScaler ( bool loadIntoMap = false )

explicit

This constructor tries to find the "ScalerTree" and uses it (if requested) to load the scaler data into the map.

Parameters

[in] loadIntoMap Flag telling TScaler to load all scaler data into fScalerMap.

◆ Draw() [1/2]

TH1D * TScaler::Draw	(	UInt_t	address,
		size_t	index = 0,
		Option_t *	option = "" )

Draw scaler differences (i.e. current scaler minus last scaler) vs. time in cycle. Passing "redraw" as option forces re-drawing of the histogram (e.g. for a different index).

◆ Draw() [2/2]

TH1D * TScaler::Draw	(	UInt_t	lowAddress,
		UInt_t	highAddress,
		size_t	index = 0,
		Option_t *	option = "" )

Draw scaler differences (i.e. current scaler minus last scaler) vs. time in cycle. Passing "redraw" as option forces re-drawing of the histogram (e.g. for a different index). The "single" options creates spectra for all single addresses in the given range (instead of one accumulative spectrum).

static double TScaler::GetLastScaler	(	TTree *	tree = nullptr,

inlinestatic

This function returns the ratio of the two scalers nominator and denominator for the last entry with a matching address for a given tree. If no tree is provided it tries to get the "RateScaler" tree from the current directory.

◆ GetScaler() [1/2]

std::vector< UInt_t > TScaler::GetScaler	(	UInt_t	address,
		ULong64_t	time ) const

Returns the vector of scaler values for address "address" at the time "time". If the time is after the last entry, we return the last entry, otherwise we return the following entry (or the current entry if the time is an exact match).

◆ GetScalerDifference()

UInt_t TScaler::GetScalerDifference	(	UInt_t	address,
		ULong64_t	time,
		size_t	index ) const

Returns the difference between "index"th scaler value for address "address" at the time "time" and the previous scaler value. If the time is after our last entry, we return the last entry divided by the number of entries, if this is before the first scaler, we just return the first scaler, otherwise we return the scaler minus the previous scaler.

◆ GetTimePeriod()

ULong64_t TScaler::GetTimePeriod ( UInt_t address )

Get time period of scaler readouts for address "address" by calculating all time differences and choosing the one that occurs most often. Returns 0 if the address doesn't exist in the map.
