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.

act()

template<typename Selector = SurfaceSelector>

template<typename propagator_state_t, typename stepper_t, typename navigator_t>

Result< void > Acts::SurfaceCollector< Selector >::act	(	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 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
navigator_t	Type of the navigator used for the propagation

Parameters

[in,out]	state	is the mutable stepper state object
[in]	stepper	The stepper in use
[in]	navigator	The navigator in use
[in,out]	result	is the mutable result object
	logger	a logger instance
