Member Function Documentation

xAOD::TrackVertexAssociationMap CP::LooseTrackVertexAssociationTool::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::LooseTrackVertexAssociationTool::getUniqueMatchVertexLink	(	const xAOD::TrackParticle &	trk,
		const xAOD::VertexContainer &	vxCont
	)			const [virtual]

This functions will return the best matched vertex Match method is same as isCompatible. but will only keep the best vertex(with mini_dz) with more than one vertices match to the same track

Implements CP::ITrackVertexAssociationTool.

StatusCode CP::LooseTrackVertexAssociationTool::initialize

void

[virtual]

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::LooseTrackVertexAssociationTool::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 after matching method 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.
