Detailed Description

User implementation for CBoolAlgoBase class doxygen documentation!

This algo looks for tiny clusters and looks to merge them with big clusters. It uses code from PolyShortestDist and says if the small cluster is close(ish) to the big one, merge it.

void cmtool::CBAlgoMergeTinyWithBig::SetMinHitsBig ( size_t nhits )

inline

Optional function: called at the beginning of 1st iteration. This is called per event. Optional function: called at the end of event ... after the last merging iteration is over. Optional function: called at the beggining of each iteration over all pairs of clusters. This provides all clusters' information in case the algorithm need them. Note this is called per iteration which may be more than once per event. Optional function: called at the end of each iteration over all pairs of clusters.
