Detailed Description

Lightweight view over a set of source blocks.

This class is a non-owning wrapper around a std::unordered_map<std::string, std::shared_ptr<Block>>.

It provides:

checked access to a block by name, with good error messages
checked access to parameters in those blocks
convenient get_val helpers from various ID forms

It is typically used inside dependent-block update lambdas:

void recalc(const BlockSrc& src, std::shared_ptr<DependentBlock> self) {
    double alpha = src.get_val("SMINPUTS", 1);
    ...
}

Constructor & Destructor Documentation

◆ BlockSrc()

BlockSrc::BlockSrc	(	const std::unordered_map< std::string, std::shared_ptr< Block > > &	m,
		std::string	ctx = `{}`
	)

explicit

Constructs a BlockSrc view from an existing map.

Parameters

m	Map of block-name to Block pointers (not owned).
ctx	Optional textual context added to error messages (e.g. name of the DependentBlock being updated).

Definition at line 19 of file SourceView.cpp.

Member Function Documentation

◆ block()

const std::shared_ptr< Block > & BlockSrc::block ( std::string_view name ) const

Returns a reference to a block by name.

If the block is missing, throws std::invalid_argument with a message mentioning the context (if provided) and the list of available blocks.

Parameters

name	Name of the block (case-sensitive as stored in the map).

Returns: Const reference to shared_ptr<Block>.

Exceptions

std::invalid_argument if the block is not found.

Definition at line 27 of file SourceView.cpp.

◆ get_param() [1/3]

std::shared_ptr< Parameter > BlockSrc::get_param	(	std::string_view	blk,
		const LhaID &	code
	)		const

Retrieves a parameter from a given block by LhaID.

If the block or parameter is missing, throws std::invalid_argument with a detailed message including available IDs.

Parameters

blk	Name of the block.
code	LhaID of the parameter.

Returns: Shared pointer to the Parameter.

Exceptions

std::invalid_argument if the block or parameter is not found.

Definition at line 42 of file SourceView.cpp.

◆ get_param() [2/3]

std::shared_ptr< Parameter > BlockSrc::get_param	(	std::string_view	blk,
		int	code
	)		const

Helper: get parameter using an integer code.

Constructs LhaID(code) and forwards to the main overload.

Parameters

blk	Name of the block.
code	Integer PDG-like code.

Returns: Shared pointer to the Parameter.

Definition at line 47 of file SourceView.cpp.

◆ get_param() [3/3]

std::shared_ptr< Parameter > BlockSrc::get_param	(	std::string_view	blk,
		std::pair< int, int >	code
	)		const

Helper: get parameter using a pair of integers.

Constructs an LhaID(code.first, code.second) and forwards.

Parameters

blk	Name of the block.
code	Pair of indices.

Returns: Shared pointer to the Parameter.

Definition at line 50 of file SourceView.cpp.

◆ get_val() [1/6]

scalar_t BlockSrc::get_val	(	std::string_view	blk,
		const LhaID &	code
	)		const

Retrieves the value of a parameter identified by an LhaID.

Parameters

blk	Name of the block.
code	LhaID of the parameter.

Returns: The current parameter value, including any imaginary component.

Definition at line 73 of file SourceView.cpp.

◆ get_val() [2/6]

scalar_t BlockSrc::get_val	(	std::string_view	blk,
		int	code
	)		const

Helper: get value from an integer code.

Parameters

blk	Name of the block.
code	Integer PDG-like code.

Returns: The current parameter value, including any imaginary component.

Definition at line 77 of file SourceView.cpp.

◆ get_val() [3/6]

scalar_t BlockSrc::get_val	(	std::string_view	blk,
		std::initializer_list< int >	code
	)		const

Retrieves the value of a parameter given as an initializer_list.

Example:

auto v = src.get_val("MASS", {25}); // H mass

auto v2 = src.get_val("YU", {3,3}); // Yukawa entry

Parameters

blk	Name of the block.
code	List of positive integer components used to build an LhaID.

Returns: The current parameter value (scalar_t).

Exceptions

std::invalid_argument if the block or parameter is missing.

Definition at line 66 of file SourceView.cpp.

◆ get_val() [4/6]

scalar_t BlockSrc::get_val	(	std::string_view	blk,
		std::initializer_list< long >	code
	)		const

Retrieves the value of a parameter given as an initializer_list.

Example:

auto v = src.get_val("MASS", {25}); // H mass

auto v2 = src.get_val("YU", {3,3}); // Yukawa entry

Parameters

blk	Name of the block.
code	List of integer components used to build an LhaID.

Returns: The current parameter value (scalar_t).

Exceptions

std::invalid_argument if the block or parameter is missing.

Definition at line 54 of file SourceView.cpp.

◆ get_val() [5/6]

scalar_t BlockSrc::get_val	(	std::string_view	blk,
		std::initializer_list< std::size_t >	code
	)		const

Retrieves the value of a parameter given as an initializer_list.

Example:

auto v = src.get_val("MASS", {25}); // H mass

auto v2 = src.get_val("YU", {3,3}); // Yukawa entry

Parameters

blk	Name of the block.
code	List of positive integer components used to build an LhaID.

Returns: The current parameter value (scalar_t).

Exceptions

std::invalid_argument if the block or parameter is missing.

Definition at line 58 of file SourceView.cpp.

◆ get_val() [6/6]

scalar_t BlockSrc::get_val	(	std::string_view	blk,
		std::pair< int, int >	code
	)		const

Helper: get value from a pair of integers.

Parameters

blk	Name of the block.
code	Pair of indices.

Returns: The current parameter value, including any imaginary component.

Definition at line 81 of file SourceView.cpp.

◆ has_block()

bool BlockSrc::has_block ( std::string_view name ) const

Checks whether a block with a given name is present.

Parameters

name	Name of the block.

Returns: True if the underlying map contains this block.

Definition at line 23 of file SourceView.cpp.

◆ raw()

const std::unordered_map< std::string, std::shared_ptr< Block > > & BlockSrc::raw ( ) const
