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, typename navigator_t>
inline void operator()(propagator_state_t &state, const stepper_t &stepper, const navigator_t &navigator, result_type &result, const Logger &logger) 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

  • navigator_t – Type of the navigator used for the propagation

  • state[inout] is the mutable stepper state object

  • stepper[in] The stepper in use

  • navigator[in] The navigator in use

  • result[inout] is the mutable result object

  • logger – the logger object

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)
