Struct Acts::VolumeCollector

template<typename Selector = VolumeSelector>
struct VolumeCollector

A Volume Collector struct templated with a Selector type.

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

Public Types

using result_type = this_result

Public Functions

template<typename propagator_state_t, typename stepper_t>
inline void operator()(propagator_state_t &state, const stepper_t &stepper, result_type &result) const

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

  • it records the volume 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
  • state[inout] is the mutable stepper state object

  • stepper[in] The stepper in use

  • result[inout] is the mutable result object

template<typename propagator_state_t, typename stepper_t>
inline void operator()(propagator_state_t&, const stepper_t&) const

Pure observer interface.

  • this does not apply to the volume collector

Public Members

Selector selector

The selector used for this volume.

struct this_result

Simple result struct to be returned It has all the VolumeHit objects that are collected (and thus have been selected)

Public Members

std::vector<VolumeHit> collected
