Member Function Documentation

bool cmtool::CBAlgoPolyShortestDist::Bool ( const ::cluster::ClusterParamsAlg &  cluster1, const ::cluster::ClusterParamsAlg &  cluster2  )

virtual

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. Core function: given the CPAN input, return whether a cluster should be merged or not.

Reimplemented from cmtool::CBoolAlgoBase.
