Detailed Description

Class to decide and return which approaching surface to be taken, it's a generic descriptor for n surfaces.

Constructor & Destructor Documentation

GenericApproachDescriptor()

Acts::GenericApproachDescriptor::GenericApproachDescriptor ( std::vector< std::shared_ptr< const Surface > > aSurfaces )

explicit

A generic approach descriptor for new Acts::Surface objects passing ownership.

Parameters

aSurfaces

are the approach surfaces

Member Function Documentation

approachSurface()

NavigationTarget Acts::GenericApproachDescriptor::approachSurface ( const GeometryContext & gctx, const Vector3 & position, const Vector3 & direction, const BoundaryTolerance & boundaryTolerance, double nearLimit, double farLimit ) const

overridevirtual

Get the approach surface to the layer.

Parameters

gctx	The current geometry context object, e.g. alignment
position	The global position to start the approach from
direction	The momentum vector
boundaryTolerance	The boundary check prescription
nearLimit	The minimum distance for an intersection to be considered
farLimit	The maximum distance for an intersection to be considered

Returns

: a NavigationTarget

Implements Acts::ApproachDescriptor.

containedSurfaces() [1/2]

const std::vector< const Surface * > & Acts::GenericApproachDescriptor::containedSurfaces ( ) const

overridevirtual

return all contained surfaces of this approach descriptor

Returns

Const reference to vector of contained surface pointers

Implements Acts::ApproachDescriptor.

containedSurfaces() [2/2]

std::vector< const Surface * > & Acts::GenericApproachDescriptor::containedSurfaces ( )

overridevirtual

Non-const version.

Returns

Mutable reference to vector of contained surface pointers

Implements Acts::ApproachDescriptor.

registerLayer()

void Acts::GenericApproachDescriptor::registerLayer ( const Layer & lay )

overridevirtual

Register the Layer to the surfaces.

Parameters

lay	is the layer to be registered

Implements Acts::ApproachDescriptor.
