Collaboration diagram for Acts::VertexInfo:

Public Member Functions
	VertexInfo (const Acts::Vertex &constr, const Acts::Vector4 &pos)
	Construct VertexInfo with constraint and position.

Public Attributes
Acts::Vertex	constraint
	Vertex constraint for fitting procedure.
std::map< InputTrack, const BoundTrackParameters >	impactParams3D
	Map of 3D impact parameters for each associated track.
Acts::Vector4	linPoint {Acts::Vector4::Zero()}
	Point where all associated tracks are linearized.
Acts::Vector4	oldPosition {Acts::Vector4::Zero()}
	Vertex position from the last iteration of the fit.
bool	relinearize = true
	Flag indicating if associated tracks need relinearization.
Acts::Vector4	seedPosition {Acts::Vector4::Zero()}
	The seed position (i.e., the first estimate for the vertex position as obtained by the vertex seed finder).
std::vector< InputTrack >	trackLinks
	Vector of all tracks that are currently assigned to vertex.

Detailed Description

Helper struct for storing vertex related information.

Deprecated: Superseded by VertexFitCandidate, which describes the vertex to be fitted, and the private fitter cache, which holds the fitter's per-vertex scratch data. This type merges the two and is kept only so that code written against the pre-split AdaptiveMultiVertexFitter::State keeps compiling; it is no longer used by the fitter itself.

Constructor & Destructor Documentation

Acts::VertexInfo::VertexInfo	(	const Acts::Vertex &	constr,
		const Acts::Vector4 &	pos )

Construct VertexInfo with constraint and position.

Parameters

constr	Vertex constraint for the fitting procedure
pos	Initial position for linearization, old position, and seed
