Detailed Description

Nested State struct.

It acts as an internal state which is created for every propagation and meant to keep thread-local navigation information.

Constructor & Destructor Documentation

◆ State()

Acts::Navigator::State::State ( const Options & options_ )

explicit

Constructor with navigation options.

Parameters

options_ The navigation options for this state

Member Function Documentation

◆ navBoundary()

NavigationTarget & Acts::Navigator::State::navBoundary ( )

Get reference to current navigation boundary.

Returns: Reference to current boundary intersection

◆ navCandidate()

NavigationTarget & Acts::Navigator::State::navCandidate ( )

Get reference to current navigation candidate.

Returns: Reference to current boundary intersection

◆ navLayer()

NavigationTarget & Acts::Navigator::State::navLayer ( )

Get reference to current navigation layer.

Returns: Reference to current layer intersection

◆ navSurface()

NavigationTarget & Acts::Navigator::State::navSurface ( )

Get reference to current navigation surface.

Returns: Reference to current navigation target

Member Data Documentation

◆ freeCandidates

std::vector<std::pair<const Surface*, bool> > Acts::Navigator::State::freeCandidates {}

Free candidates not part of the tracking geometry.

and a boolean indicating whether the surface has already been reached during propagation
