Detailed Description

Class managing the creation of a new recob::Cluster object.

A Creator is a class that creates a temporary data product, and at the end it yields it to the caller for storage. This last step should be by move construction, although a copy method is also provided.

An example of creating a Cluster object:

Todo:: Add the example!

cluster::ClusterCreator cluster(...);
cluster.push_back(cluster.move()); // cluster content becomes invalid

This is a one-step creation object: the cluster is constructed at the same time the ClusterCreator is, and no facility is offered to modify the constructed cluster, or to create another one.

Member Function Documentation

recob::Cluster const& cluster::ClusterCreator::copy ( ) const

inline

Returns the constructed wire.

Returns: a constant reference to the constructed wire

Despite the name, no copy happens in this function. Copy takes place in the caller code as proper; for example:

// be cluster a ClusterCreator instance:
std::vector<recob::Cluster> Clusters;
cluster.copy();                        // nothing happens
Clusters.push_back(cluster.copy());    // here a copy happens
recob::Cluster single_cluster(cluster.copy()); // copied again

inline

Prepares the constructed hit to be moved away.

Returns: a right-value reference to the constructed hit

Despite the name, no move happens in this function. Move takes place in the caller code as proper; for example:

// be cluster a ClusterCreator instance:
std::vector<recob::Cluster> Clusters;
cluster.move();                        // nothing happens
Clusters.push_back(cluster.move());    // here the move happens
recob::Cluster single_cluster(cluster.move()); // wrong! cluster is empty now
