Detailed Description

Abstract base class for a single element of an LHA/FLHA block.

An AbstractElement represents one logical "entry" in a block:

• it has a unique identifier (LhaID) built from the line indices,
• it can expose an optional scale and binning,
• it can be serialized to a string or to a DBNode.

Concrete implementations (LhaElement<T>) provide the actual value type.

Constructor & Destructor Documentation

AbstractElement()

AbstractElement::AbstractElement ( const LhaID &  id_ )

inlineexplicit

Constructs an AbstractElement with a given identifier.

Parameters

id	Unique LhaID associated with this element.

virtualdefault

Virtual destructor.

Member Function Documentation

getBinning()

virtual std::pair< double, double > AbstractElement::getBinning ( ) const

pure virtual

Returns the binning associated to this element.

The convention is defined by derived classes. For LhaElement<T>, if no bin is defined, a dummy pair (-1.0, -1.0) is returned.

Returns

Pair (low, high) bin edges.

Implemented in LhaElement< T >.

getId()

LhaID AbstractElement::getId ( ) const

inline

Returns the identifier of the element.

The identifier encodes the integer indices of the line (e.g. PDG codes, matrix indices), excluding value/scale/scheme/bin.

Returns

LhaID of this element.

Definition at line 60 of file lha_elements.h.

getScale()

virtual double AbstractElement::getScale ( ) const

pure virtual

Returns the renormalization scale of this element.

For blocks without a scale, derived classes typically return 0.

Returns

Scale value Q.

Implemented in LhaElement< T >.

toDBNode()

virtual std::shared_ptr< DBNode > AbstractElement::toDBNode ( ) const

pure virtual

Converts the element into a DBNode for database/storage use.

The node typically stores:

• "central_value" : the value,
• "scale" : Q (if available),
• "renormalization_scheme" : scheme (if available),
• "bin_low", "bin_high" : bin edges (if available).

Returns

Shared pointer to a newly created DBNode.

Implemented in LhaElement< T >.

toString()

virtual std::string AbstractElement::toString ( ) const

pure virtual

Converts the element to a line-like string representation.

The exact format is implementation-dependent; for LhaElement<T> it typically contains:

• the ID (indices),
• the value,
• optionally Q and the renormalization scheme.

Returns

String representation of the element.

Implemented in LhaElement< T >.
