Member Function Documentation

approachSurface()

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

pure virtual

Get the surface on approach.

Parameters

gctx	The current geometry context object, e.g. alignment
position	is the position from start of the search
direction	is the direction at the start of the search
boundaryTolerance	is the boundary check directive
nearLimit	The minimum distance for an intersection to be considered
farLimit	The maximum distance for an intersection to be considered

Returns

is a surface intersection

Implemented in Acts::GenericApproachDescriptor.

containedSurfaces() [1/2]

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

pure virtual

Get all the contained surfaces.

Returns

all contained surfaces of this approach descriptor

Implemented in Acts::GenericApproachDescriptor.

containedSurfaces() [2/2]

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

pure virtual

Non-const version.

Returns

Mutable reference to all contained surfaces of this approach descriptor

Implemented in Acts::GenericApproachDescriptor.

registerLayer()

virtual void Acts::ApproachDescriptor::registerLayer ( const Layer & lay )

pure virtual

Register Layer Links the layer to the approach surfaces.

Parameters

lay	is the layer to be assigned

Implemented in Acts::GenericApproachDescriptor.
