Detailed Description

template<typename T>
class TTClusterAssociator< T >

Plugin to create the MC truth for TTClusters.

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.

TTClusterAssociator()

template<typename T >

TTClusterAssociator< T >::TTClusterAssociator ( 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

Exit if real data

Get the PixelDigiSimLink

Get the TrackingParticles

Preliminary task: map SimTracks by TrackingParticle Prepare the map








































Loop over TrackingParticles

Make the pointer to the TrackingParticle

Get the EncodedEventId

Loop over SimTracks inside TrackingParticle

Use the unique SimTrack Id (which is SimTrack ID + EncodedEventId)

End of loop over TrackingParticles

Loop over InputTags to handle multiple collections

Prepare output

Get the Clusters already stored away

Prepare the necessary maps

Loop over the input Clusters

Get the DetSets of the Clusters

Make the reference to be put in the map

Prepare the maps wrt TTCluster

Get the PixelDigiSimLink Safety check added after new digitizer (Oct 2014)

























Sensor is not found in DigiSimLink. Set MC truth to NULL for all hits in this sensor. Period.
























Get the Digis and loop over them

No SimLink is found by definition Then store NULL MC truth for all the digis






















Go to the next sensor

Get the Digis and loop over them

Loop over PixelDigiSimLink

Find the link and, if there's not, skip

Get SimTrack Id and type

Prepare the SimTrack Unique ID

Get the corresponding TrackingParticle

Store the TrackingParticle

Prepare the maps wrt TrackingParticle

Fill the auxiliary map

In case no TrackingParticle is found, store a NULL pointer

End of loop over PixelDigiSimLink

End of loop over all the hits composing the Cluster

Check that the cluster has a non-NULL TP pointer

In case no TrackingParticle is found at all, drop the map element

Use "erase by key"

End of loop over all the TTClusters of the event

Clean the maps that need cleaning Prepare the output map wrt TrackingParticle




Get the vector of references to TTCluster

Sort and remove duplicates

Put the maps in the association object

Put output in the event
