(

const std::string &

libName

)

Loads a physics list plugin library.

This method opens the library and creates the physics list it contains.

Parameters

libName

Full path to the library file.

bool GGSMCPluginManager::LoadPlugin

(

const std::string &

libName

)

Loads a plugin library.

This method opens the library and gives access to the plugin objects (user actions and sensitive detectors) inside it.

Parameters
