Detailed Description

This class defines an analytical response function for the GET input signal.

The class is abstract and has to be derivated for specific functions definition (in order to be written / read) in GET definition files).

Constructor & Destructor Documentation

GETResponseFct::GETResponseFct

(

GETObject &

obj

)

Constructor. The associated function is not defined, and a call to SetFunction is required. The dimension of the first channel of the object is used for the process definition.

Parameters

obj	a core object of the GET system

GETResponseFct::GETResponseFct	(	u_int	n = 0,
		double	dt = 0.01
	)

Constructor. The associated function is not defined, and a call to SetFunction is required.

Parameters

n	sampling size of the channels
dt	sampling period (us)

GETResponseFct::GETResponseFct	(	GETObject &	obj,
		TF1 *	f
	)

Constructor from a ROOT TF1 function. The TF1 function is adopted by the current instance. The response function sample is computed, so parameters should be set before calling the constructor, or the UpdateFunction should be called. The dimension of the first channel of the object is used for the process definition.

Parameters

obj	a core object of the GET system
f	ROOT function pointer

References SetFunction().

GETResponseFct::GETResponseFct	(	u_int	n,
		double	dt,
		TF1 *	f
	)

Constructor from a ROOT TF1 function. The TF1 function is adopted by the current instance. The response function sample is computed, so parameters should be set before calling the constructor, or the UpdateFunction should be called.

Parameters

n	sampling size of the channels
dt	sampling period (us)
f	ROOT function pointer

References SetFunction().

GETResponseFct::GETResponseFct	(	GETObject &	obj,
		const string	name,
		double(*)(const double[], const double[])	fptr,
		u_int	npar,
		double *	vpar = NULL
	)

Constructor from a function pointer. If the array of parameter values is set (non NULL pointer), the response function sample is computed, else the UpdateFunction should be called. The dimension of the first channel of the object is used for the process definition.

Parameters

obj	a core object of the GET system
name	function name (for TF1)
fptr	function pointer
npar	number of parameters
vpar	array of parameter values

References GETFunction::fct_def, and UpdateFunction().

GETResponseFct::GETResponseFct	(	u_int	n,
		double	dt,
		const string	name,
		double(*)(const double[], const double[])	fptr,
		u_int	npar,
		double *	vpar = NULL
	)

Constructor from a function pointer. If the array of parameter values is set (non NULL pointer), the response function sample is computed, else the UpdateFunction should be called.

Parameters

n	sampling size of the channels
dt	sampling period (us)
name	function name (for TF1)
fptr	function pointer
npar	number of parameters
vpar	array of parameter values

References GETFunction::fct_def, and UpdateFunction().

GETResponseFct::GETResponseFct

(

const GETResponseFct &

proc

)

Copy constructor.

Parameters

proc	object to copy

References UpdateFunction().

GETResponseFct::~GETResponseFct ( )

virtual

Destructor.

Member Function Documentation

GETResponseFct::ClassDef	(	GETResponseFct	,
		0
	)

for use within ROOT.

GETResponseFct::GObjectV ( GETResponseFct  )

private

Macro from GCpp library that defines the following functions:

• ClassName(): return the real class name of the object
• StaticClassName(): return the used class name of the object (that may be a base class of the real object).
• IsInstanceOf<T>(): return true if the current object is an instance of the template class name argument
• Clone(): return an allocated copy of the object.

void GETResponseFct::Init ( u_int  n, double  dt  )

virtual

Initialization of response function sample. If the analytical function is defined, the response function sample is computed.

Parameters

n	sampling size of the function
dt	sampling time step

Reimplemented from GETResponse.

References GETResponse::Init(), and UpdateFunction().

void GETResponseFct::SetFunction	(	TF1 *	f,
		bool	calc = true
	)

Define the associated TF1 function. If the sample dimension is set, the response function sample is computed if calc is true.

Parameters

f	function pointer (adopted)
calc	whether the response function sample is computed (if parameters are set...)

void GETResponseFct::UpdateFunction ( )

inline

Compute the function sample from the TF1 function pointer.
