Detailed Description

Wrapper class used to contain all the wrapper functions.

Deprecated:: The class-based C++ wrapper on LHAPDF will be retired in a forthcoming release of LHAPDF in favour of the namespaced wrapper declared in LHAPDF.h. Please convert client code which uses the class interface to use the new interface instead. Typically, this will just involve changing the header include from "LHAPDF/LHAPDFWrap.h" to "LHAPDF/LHAPDFWrap.h", changing any constructors to initialisation functions, and replacing LHAPDFWrap objects with an LHAPDF namespace. For example,

#include "LHAPDF/LHAPDFWrap.h"
LHAPDFWrap pdf = LHAPDFWrap("MRST2004qed.LHgrid", 0);
pdf.getDescription();

would be replaced by

#include "LHAPDF/LHAPDF.h"
LHAPDF::initPDFByName("MRST2004qed.LHgrid", 0);
LHAPDF::getDescription();

Constructor & Destructor Documentation

◆ LHAPDFWrap() [1/4]

LHAPDFWrap::LHAPDFWrap ( const std::string & name )

Typical constructor with PDF set 'name' 'name' is the name of the grid or data file of the desired set.

◆ LHAPDFWrap() [2/4]

LHAPDFWrap::LHAPDFWrap	(	const std::string &	name,
		int	memset
	)

Typical constructor with PDF set 'name' and subset 'memset' 'name' is the name of the grid or data file of the desired set.

◆ LHAPDFWrap() [3/4]

LHAPDFWrap::LHAPDFWrap	(	int	nset,
		const std::string &	name
	)

Typical constructor (when multiple PDF sets need to be initialized) with pdfset 'name' and subset 'memset'. 'name' is the name of the grid or data file of the desired set. int nset specifies the reference number for the set to be initialized

◆ LHAPDFWrap() [4/4]

LHAPDFWrap::LHAPDFWrap	(	int	nset,
		const std::string &	name,
		int	memset
	)

Typical constructor (when multiple PDF sets need to be initialized) with PDF set 'name' and subset 'memset'. 'name' is the name of the grid or data file of the desired set. int nset specifies the reference number for the set to be initialized

Member Function Documentation

◆ xfx() [1/2]

std::vector<double> LHAPDFWrap::xfx	(	double	x,
		double	Q
	)

Returns a vector xf(x, Q) with index 0 < i < 12. 0..5 = tbar, ..., ubar, dbar; 6 = g; 7..12 = d, u, ..., t

◆ xfx() [2/2]

double LHAPDFWrap::xfx	(	double	x,
		double	Q,
		int	fl
	)

Returns xf(x, Q) for flavour fl - this time the flavour encoding is as in the LHAPDF manual... -6..-1 = tbar,...,ubar, dbar 1..6 = duscbt 0 = g
