Detailed Description

TightTrackVertexAssociationTool: apply tight track-vertex association process, the main idea is base on track used in vertex fit and recover the rest by loose method

Member Function Documentation

xAOD::TrackVertexAssociationMap CP::TightTrackVertexAssociationTool::getUniqueMatchMap	(	std::vector< const xAOD::TrackParticle * > &	trk_list,
		std::vector< const xAOD::Vertex * > &	vx_list
	)			const [virtual]

This functions related to the previous functions, will return a map<const xAOD::Vertex*, std::vector<const xAOD::TrackParticle*> > (defined as TrackVertexAssociationMap) to store the best matched tracks for each vertex. Note: the dummy vertex will be also stored in the map but the track stored vector which assigned to this vertex will be empty

Implements CP::ITrackVertexAssociationTool.

ElementLink< xAOD::VertexContainer > CP::TightTrackVertexAssociationTool::getUniqueMatchVertexLink	(	const xAOD::TrackParticle &	trk,
		const xAOD::VertexContainer &	vxCont
	)			const [virtual]

This functions will return the best matched vertex For ambiguity resolve: 1) If this track is used in vertex fit, always pick up the vertex fitted using this track. 2) If this track is not used for any vertex fit, pick up the vertex with mini_dz

Dummy implementation of the initialisation function

It's here to allow the dual-use tools to skip defining an initialisation function. Since many are doing so...

Reimplemented from asg::AsgTool.

bool CP::TightTrackVertexAssociationTool::isCompatible	(	const xAOD::TrackParticle &	trk,
		const xAOD::Vertex &	vx
	)			const [virtual]

This function will return the decision of whether the track is matched to the Vertex Not sure whether the track is matched to best choice Note: Only apply to good vertex(vx->vertexType()!=xAODVxType::NoVtx), return false if vertex is a dummy one

Implements CP::ITrackVertexAssociationTool.
