Detailed Description

Ownership model:

• GMagneto owns a map of field objects (GField) created via dynamic plugin loading.
• For each field it also owns a corresponding G4FieldManager created by create_FieldManager().

Lifecycle:

• Fields and managers are constructed during GMagneto() based on the field definitions produced by gfields::get_GFieldDefinition().
• Maps live for the lifetime of the GMagneto instance.

Constructor & Destructor Documentation

GMagneto()

GMagneto::GMagneto ( const std::shared_ptr< GOptions > & gopts )

explicit

Parameters

gopts

Shared options used for configuration and logging.

This constructor:

1. Builds the list of GFieldDefinition objects from options,
2. Loads each corresponding plugin library using the factory manager,
3. Instantiates the field and calls load_field_definitions(),
4. Creates and stores a G4FieldManager via create_FieldManager().

Member Function Documentation

getField()

std::shared_ptr< GField > GMagneto::getField ( std::string name )

inline

Parameters

name	Field name key.

Returns

Shared pointer to the requested GField instance.

If the field is not found, an error is logged and execution is terminated by the logger.

Definition at line 75 of file gmagneto.h.

getFieldMgr()

std::shared_ptr< G4FieldManager > GMagneto::getFieldMgr ( std::string name )

inline

Parameters

name	Field name key.

Returns

Shared pointer to the requested G4FieldManager.

If the field manager is not found, an error is logged and execution is terminated by the logger.

Definition at line 89 of file gmagneto.h.

isField()

bool GMagneto::isField ( const std::string & name ) const

inline

Parameters

name	Field name key.

Returns

True if name is present in the internal field map.
