0012 /** \class EcalTrigPrimCompactColl
0013 
0014 This collection is used to store ECAL trigger primitive with a low footpring in ROOT EDM file.
0015 
0016 Note that only the time sample of interest time is stored. In nornal operation data contains only this time sample.
0017 
0018 The interface is similar to EcalTriggerPrimitiveSample one. The collection can also be converted to an EcalTrigPrimDigiCollection
0019 with the method toEcalTrigPrimDigiCollection().
0020 
0021 The collection is generated with EcalCompactTrigPrimProducer module from package RecoLocalCalo/EcalRecProducers.
