Detailed Description

DBNode provider for LHA / SLHA / FLHA sources.

This provider delegates the heavy lifting to DBManager:

• DBManager::read_from_file() for parsing,
• DBManager::add_lha_prototype() for enriching the set of block prototypes used by the LHA parser.

Constructor & Destructor Documentation

LhaDBNodeProvider()

LhaDBNodeProvider::LhaDBNodeProvider ( fs::path  src_path_ )

inline

Constructs a provider bound to a specific source path.

Parameters

src_path

Path to an LHA / SLHA / FLHA file.

Definition at line 35 of file LhaDBNodeProvider.h.

Member Function Documentation

add_lha_prototype()

void LhaDBNodeProvider::add_lha_prototype	(	BlockName	blockName,
		size_t	itemCount = 2,
		size_t	valueIdx = 1,
		int	scaleIdx = -1,
		int	rgIdx = -1,
		int	binIdx = -1,
		bool	globalScale = false
	)

Adds a new LHA block prototype to the global set.

This is a convenience wrapper around DBManager::add_lha_prototype(), allowing clients to register additional block layouts before parsing.

The arguments follow the Prototype layout:

• blockName : block identifier (case-insensitive),
• itemCount : number of columns in each line,
• valueIdx : index of the value column,
• scaleIdx : index of the scale column (-1 if none),
• rgIdx : index of the renormalization scheme column (-1 if none),
• binIdx : index of the bin lower edge (-1 if unbinned),
• globalScale : true if the block uses a global Q= header.

Input indices are checked for basic consistency and will trigger a logged error if the configuration is invalid.

provide_db_as_node()

std::shared_ptr< DBNode > LhaDBNodeProvider::provide_db_as_node ( )

overridevirtual

Loads the underlying LHA file and returns it as a DBNode tree.

Internally this is equivalent to:

DBManager db;
return db.read_from_file(src_path);

Returns

Shared pointer to the root DBNode representing the LHA content.

Exceptions

std::runtime_error

if file or parsing errors occur.

Implements IDBNodeProvider.
