Detailed Description

template<typename T>
class TTStubAssociator< T >

Plugin to create the MC truth for TTStubs.

After moving from SimDataFormats to DataFormats, the template structure of the class was maintained in order to accomodate any types other than PixelDigis in case there is such a need in the future.

Constructor & Destructor Documentation

template<typename T >

TTStubAssociator< T >::TTStubAssociator ( const edm::ParameterSet & iConfig )

explicit

Constructors.

Close class.

NOTE since pattern hit correlation must be performed within a stacked module, one must store Clusters in a proper way, providing easy access to them in a detector/member-wise way

Implementation of methods

Here, in the header file, the methods which do not depend on the specific type <T> that can fit the template. Other methods, with type-specific features, are implemented in the source file.Constructors

Date: 2013, Jul 19Implement the producer

Exit if real data

Exit if the vectors are uncorrectly dimensioned

Loop over the InputTags to handle multiple collections

Prepare output

Get the Stubs already stored away

Get the Cluster MC truth

Prepare the necessary maps

Loop over the input Stubs

Get the DetSets of the Clusters

Make the reference to be put in the map

Get the two clusters

Fill the inclusive map which is careless of the stub classification

Prepare the maps wrt TrackingParticle

Fill the auxiliary map

GENUINE for clusters means not combinatoric and not unknown: same MC truth content MUST be found in both clusters composing the stub

If at least one cluster is unknown, it means either unknown, either combinatoric Do nothing, and go to the next Stub

Here both are clusters are genuine/combinatoric If both clusters have some known SimTrack content they must be compared to each other

If both clusters are genuine, they must be associated to the same TrackingParticle in order to return a genuine stub. Period. Note we can perform safely this comparison because, if both clusters are genuine, their TrackingParticle shall NEVER be NULL

Two genuine clusters with same SimTrack content mean genuine

Fill the map: by construction, this will always be the first time the stub is inserted into the map: no need for "find"

At this point, go to the next Stub

It means combinatoric

End of two genuine clusters

Here, at least one cluster is combinatoric

Skip NULL pointers

Same SimTrack is present in both clusters

If two different SimTracks are found in both clusters, then the stub is for sure combinatoric

End of double loop over SimTracks of both clusters

If two different SimTracks are found in both clusters, go to the next stub

No SimTracks were found to be in both clusters

Only one SimTrack was found to be present in both clusters even if one of the clusters (or both) are combinatoric: this means there is only one track that participates in both clusters, hence the stub is genuine

Fill the map: by construction, this will always be the first time the stub is inserted into the map: no need for "find"

At this point, go to the next Stub

End of one single SimTrack in both clusters

End of "at least one cluster is combinatoric"

End of "both clusters are known, somehow..."

End of loop over Stubs

Clean the only map that needs cleaning Prepare the output map wrt TrackingParticle

Get the vector of references to TTStub

Sort and remove duplicates

Put the vector in the output map

Also, create the pointer to the TTClusterAssociationMap

Put the maps in the association object

Put output in the event

End of loop over InputTags
