Detailed Description

template<typename T>
class LhaElement< T >

Template concrete implementation of an LHA/FLHA block element.

LhaElement<T> represents an element whose numerical content is of type T (e.g. double or std::string). It is constructed from:

• a Prototype describing the block structure (column indices),
• a parsed line (vector of strings).

From these, it:

• determines the identifier (LhaID) by inspecting columns other than value/scale/scheme/bin,
• extracts the value of type T,
• optionally extracts:
  • the renormalization scale Q,
  • the renormalization scheme,
  • a binning (low, high).

Template Parameters

T	Value type stored by the element (e.g. double or std::string).

Definition at line 135 of file lha_elements.h.

Constructor & Destructor Documentation

LhaElement()

template<typename T >

LhaElement< T >::LhaElement	(	const Prototype &	prototype,
		const std::vector< std::string > &	line
	)

Constructs an LhaElement from a prototype and a line of data.

The constructor:

• normalizes the indices using the Prototype (value, scale, scheme, bin),
• builds the element ID via encodeId(),
• parses the scale Q (either global header scale or per-line),
• parses the renormalization scheme (if present),
• parses the binning (if present),
• converts the value token to type T.

Parameters

prototype	Description of the block structure.
line	Vector of tokens representing one line of the block.

Exceptions

std::runtime_error

if indices are inconsistent or conversion fails.

Definition at line 43 of file lha_elements.cpp.

Member Function Documentation

getBinning()

template<typename T >

std::pair< double, double > LhaElement< T >::getBinning ( ) const

inlineoverridevirtual

Returns the binning associated with the element.

If no binning is defined, the default pair (-1.0, -1.0) is returned.

Returns

Pair (low, high) bin edges.

Implements AbstractElement.

Definition at line 211 of file lha_elements.h.

getScale()

template<typename T >

double LhaElement< T >::getScale ( ) const

inlineoverridevirtual

Returns the renormalization scale Q of the element.

If no scale is defined, 0.0 is returned by convention.

Returns

Scale value Q.

Implements AbstractElement.

Definition at line 202 of file lha_elements.h.

getScheme()

template<typename T >

RenormalizationScheme LhaElement< T >::getScheme ( ) const

inline

Returns the renormalization scheme of the element.

If no scheme is defined, RenormalizationScheme::NONE is returned.

Returns

RenormalizationScheme of this element.

Definition at line 193 of file lha_elements.h.

getValue()

template<typename T >

T LhaElement< T >::getValue ( ) const

inline

Returns the stored value of the element.

Returns

Value of type T.

Definition at line 184 of file lha_elements.h.

toDBNode()

template<typename T >

std::shared_ptr< DBNode > LhaElement< T >::toDBNode ( ) const

overridevirtual

Converts the element to a DBNode representation.

The returned DBNode contains at least:

• "central_value" : T and optionally:
• "scale" : double,
• "renormalization_scheme": int,
• "bin_low", "bin_high" : double.

Returns

Shared pointer to a new DBNode containing the element data.

Implements AbstractElement.

Definition at line 106 of file lha_elements.cpp.

toString()

template<typename T >

std::string LhaElement< T >::toString ( ) const

overridevirtual

Returns a line-like string representation of the element.

The exact format is: "<id>\t<value>[\t<scale>][\t<scheme>]\n"

where the optional parts are printed only if available.

Returns

String representation of this element.

Implements AbstractElement.
