◆ Init()

static void Herwig::PowhegShowerHandler::Init ( )
static

The standard Init function used to initialize the interfaces.

Called exactly once for each class by the class description system before the main function starts or when this class is dynamically loaded.

◆ operator=()

PowhegShowerHandler& Herwig::PowhegShowerHandler::operator= ( const PowhegShowerHandler )
private
