Detailed Description

A base class for describing clusters of EEMC towers.

This class is designed to represent EEMC tower clusters. By "tower cluster" I mean a cluster of StEEmcTower objects, which can in principle be clusters of tower, preshower or postshower elements.

By convention, we assume that the first tower added to the cluster is the "seed" tower.

Each cluster should be assigned its own unique "key" by the maker which produces it.

This class makes no assumtion about the size and/or shape of the cluster.

Constructor & Destructor Documentation

StEEmcIUCluster::~StEEmcIUCluster ( )

If we have created an StEmcCluster, delete it

Member Function Documentation

void StEEmcIUCluster::add ( StEEmcTower  tower,
Float_t  weight = 1.0 

add a tower to this cluster. The code assumes that the first tower added is the seed tower, and hence is the most energetic.

Bool_t StEEmcIUCluster::operator== ( const StEEmcIUCluster other) const

Tests whether the cluster has the same seed tower as another cluster. If so, these clusters are considered equal

Definition at line 58 of file StEEmcIUCluster.h.

References StEEmcTower::index(), and tower().

StEmcCluster * StEEmcIUCluster::stemc ( )

Create and return an StEmcCluster using this cluster's hits, energy, etc... The StEmcCluster will be deleted when this cluster's destructor is called.
