Detailed Description

The static blueprint node wraps a single already-constructred TrackingVolume.

The node will present this volume to its hierarchy. The volume is given as mutable, and will be potentially enlarged in order to connect to neighboring volumes.

In case the volume already has child volumes, they will be retained.
In case the volume already has a registered navigation policy, it will be overwritten with the one configured on this node, regardless of content.

Constructor & Destructor Documentation

◆ StaticBlueprintNode()

Acts::Experimental::StaticBlueprintNode::StaticBlueprintNode ( std::unique_ptr< TrackingVolume > volume )

explicit

Construct the static node from an existing volume.

Parameters

volume The volume to wrap

Member Function Documentation

◆ addToGraphviz()

void Acts::Experimental::StaticBlueprintNode::addToGraphviz ( std::ostream & os ) const

overrideprotectedvirtual

Method that writes a representatiohn of this node only to graphviz.

This should generally not be called on its own, but through the BlueprintNode::graphviz method.

Parameters

os	The stream to print to

Reimplemented from Acts::Experimental::BlueprintNode.

◆ build()

Volume & Acts::Experimental::StaticBlueprintNode::build	(	const BlueprintOptions &	options,
		const GeometryContext &	gctx,
		const Logger &	logger = Acts::getDummyLogger() )

overridevirtual

This method is called during the build phase of the blueprint tree construction.

It returns a single Acts::Volume which represents transform and bounds of the entire subtree. This does not have to correspond to the final Acts::TrackingVolume, some node types will produce temporary volume representations. Lifetime of the returned volume is managed by the source node! Nodes higher in the hierarchy will issue resizes down the tree hierarchy. This is not done through a direct hierarchy, but coordinated by the respective node type, by internally consulting its children.

Note: Generally, you should not need to to call this method directly. The construction should usually be done through the special Acts::Experimental::Blueprint class.

Parameters

options	The global construction options
gctx	The geometry context for construction (usually nominal)
logger	The logger to use for output during construction

Returns: The volume used for communicating transform and size up the hierarchy Build-phase of the blueprint construction. Returns the wrapped volume for sizing.

Implements Acts::Experimental::BlueprintNode.

◆ connect()

PortalShellBase & Acts::Experimental::StaticBlueprintNode::connect	(	const BlueprintOptions &	options,
		const GeometryContext &	gctx,
		const Logger &	logger = Acts::getDummyLogger() )

overridevirtual

This method is called during the connect phase.

This phase handles the creation and connection of portals (instances of Acts::PortalLinkBase). After the build-phase has completed, the volume sizes are final. Each node will consult its fully sized volume to produce boundary surfaces. Each boundary surface is then turned into a Acts::TrivialPortalLink, which in turn produces a one-sided portal (see Acts::Portal documentation)

Some nodes (like Acts::Experimental::ContainerBlueprintNode) will take action on their children, and unify the connected portals.

After a node's processing has completed, it returns a reference to a Acts::PortalShellBase, which represents a set of portals in a specific geometry arrangement. The returned object lifetime is managed by the returning node.

Parameters

options	The global construction options
gctx	The geometry context for construction (usually nominal)
logger	The logger to use for output during construction

Returns: Reference to portal shell containing connected portals for this node

Implements Acts::Experimental::BlueprintNode.

◆ finalize()

void Acts::Experimental::StaticBlueprintNode::finalize	(	const BlueprintOptions &	options,
		const GeometryContext &	gctx,
		TrackingVolume &	parent,
		const Logger &	logger = Acts::getDummyLogger() )

overridevirtual

This method is called during the finalize phase.

This phase handles:

Registering portals into their final volumes
Registering volumes into their parents
Creating navigation policies
(In future) Handle geometry identification assignment

At the end of this phase, each node will have transferred any temporary resources created during the build, that need to be retained, into the final Acts::TrackingGeometry, and can be safely destroyed.

Note: The parent for volumes, portals, etc to be registered in is passed in as an argument, rather than being implicitly determined from the parent node. This is done so that nodes can remove themselves from the final volume hierarchy, like container nodes or the Acts::Experimental::MaterialDesignatorBlueprintNode.

Parameters

options	The global construction options
gctx	The geometry context for construction (usually nominal)
parent	The parent volume to register in
logger	The logger to use for output during construction

Implements Acts::Experimental::BlueprintNode.

◆ name()

const std::string & Acts::Experimental::StaticBlueprintNode::name ( ) const

overridevirtual

Get the name of this node.

It is automatically taken from the wrapped volume

Returns: The name of the volume

Implements Acts::Experimental::BlueprintNode.

◆ navigationPolicyFactory()

const NavigationPolicyFactory * Acts::Experimental::StaticBlueprintNode::navigationPolicyFactory ( ) const

Get the navigation policy factory for this node.

Returns: Pointer to the navigation policy factory (may be nullptr)

◆ setNavigationPolicyFactory()

virtual StaticBlueprintNode & Acts::Experimental::StaticBlueprintNode::setNavigationPolicyFactory ( std::shared_ptr< NavigationPolicyFactory > navigationPolicyFactory )

virtual

Set the navigation policy factory for this node.

Parameters

navigationPolicyFactory Shared pointer to navigation policy factory

Returns: Reference to this node for chaining
