Detailed Description

template<typename Selector = SurfaceSelector>
struct Acts::SurfaceCollector< Selector >

A Surface Collector struct templated with a Selector type

Whenever a surface is passed in the propagation that satisfies the selector, it is recorded for further usage in the flow.

template<typename Selector = SurfaceSelector>

template<typename propagator_state_t >

void Acts::SurfaceCollector< Selector >::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

Here is the caller graph for this function:

template<typename Selector = SurfaceSelector>

template<typename propagator_state_t , typename stepper_t >

void Acts::SurfaceCollector< Selector >::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 propagator 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 used for the propagation

Parameters

[in,out]	state	is the mutable stepper state object
[in]	stepper	The stepper in use
[in,out]	result	is the mutable result object
