Member Function Documentation

template<typename propagator_state_t , typename stepper_t >

void Acts::MaterialInteractor::operator() ( propagator_state_t &  state, const stepper_t &  stepper, result_type &  result  ) const

inline

Interaction with detector material for the ActionList of the Propagator.

It checks if the state has a current surface, in which case the action is performed: the covariance is transported to the position, multiple scattering and energy loss is applied according to the configuration.

Template Parameters

propagator_state_t	is the type of Propagagor state
stepper_t	Type of the stepper of the propagation

Parameters

state	is the mutable propagator state object
stepper	The stepper in use
result	is the mutable result state object
