Member Function Documentation

template<typename propagator_state_t >

void Acts::MaterialCollector::debugLog ( propagator_state_t &  state, const std::function< std::string()> &  logAction  ) const

inlineprivate

The private propagation debug logging

It needs to be fed by a lambda function that returns a string, that guarantees that the lambda is only called in the state.debug == true case in order not to spend time when not needed.

Template Parameters

propagator_state_t

Type of the propagator state

Parameters

state	the propagator state for the debug flag, prefix and length
logAction	is a callable function that returns a streamable object

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

inline

Collector action for the ActionList of the Propagator It checks if the state has a current surface, in which case the action is performed:

• it records the surface given the configuration

Template Parameters

propagator_state_t	is the type of Propagator 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 result object to be filled

Member Data Documentation

bool Acts::MaterialCollector::detailedCollection = false

In the detailed collection mode the material per surface is collected, otherwise only the total pathlength in X0 or L0 are recorded
