Detailed Description

The method buildSolid() dispatches on s->getType() and creates the corresponding Geant4 solid. The helper checkAndReturnParameters() validates and parses the parameter list.

Member Function Documentation

◆ buildSolid()

G4VSolid * G4NativeSystemFactory::buildSolid	(	const GVolume *	s,
		std::unordered_map< std::string, G4Volume * > *	g4s )

overrideprotectedvirtual

Parameters

s	GEMC volume definition containing the type and parameters.
g4s	Map holding cached `G4Volume` wrappers.

Returns: Pointer to the created/reused solid, or nullptr if dependencies are missing or type unsupported.

The method performs:

dependency checks (copy/boolean operations)
wrapper retrieval/creation
parameter parsing and validation
dispatch to the proper Geant4 constructor

Implements G4ObjectsFactory.

Definition at line 24 of file buildSolid.cc.

◆ checkAndReturnParameters()

std::vector< double > G4NativeSystemFactory::checkAndReturnParameters ( const GVolume * s )

protected

Parameters

s	Pointer to the GEMC volume record whose `getParameters()` string is to be parsed.

Returns: A std::vector<double> holding the converted values in the order expected by the constructor.

Some primitives have fixed parameter counts, while others have special rules:

polycones accept multiple constructor layouts, validated via modular arithmetic
polyhedra accept multiple constructor layouts, validated similarly

When validation fails, an error is emitted through the logger.

Definition at line 13 of file checkAndReturnParameters.cc.

◆ className()

std::string_view G4NativeSystemFactory::className ( ) const

inlineoverridevirtual

Returns: "G4NativeSystemFactory".

Implements G4ObjectsFactory.

Definition at line 48 of file g4NativeObjectsFactory.h.

◆ G4ObjectsFactory()

G4ObjectsFactory::G4ObjectsFactory ( const std::shared_ptr< GOptions > & g )

inlineexplicit

Parameters

g	Shared option set used to initialize the logging base and other behaviors.
