bool Add(recob::Cluster const &cluster)
Merges a single cluster into this object.

Member Function Documentation

bool cluster::ClusterMerger::Add ( recob::Cluster const &  cluster)

Merges a single cluster into this object.

Parameters
clusterthe cluster to be merged
Returns
whether the addition was successful

The two ends of the cluster are merged into this one, that gets extended.

The new cluster must have the same view as the prevopus ones and must lay on the same plane. If the new cluster has invalid plane, the current one is kept; if the current plane is invalid, it is overwritten (that means that if both are invalid, the merged cluster will also have an invalid plane).

Note that this code is crap unless the cluster is track-like.
