◆ Cache

typedef std::unordered_map<size_t,std::unique_ptr< ParticleCellAssociation > > Rec::IParticleCaloCellAssociationTool::Cache

Method to get the ParticleCellAssociation for a given Particle.

Parameters

particle	input particle
dr	cone size used for the association @ param cache cache for keeping previous results
container	cell container to be used if provided
extensionCache	A calo extension cache to be used if provided

Returns: ParticleCellAssociation* (plain ptr cache has ownership)

An alg looping over a single collection of IParticles
re-using them multiple times can use a local cache of the form std::unordered_map<size_t,std::unique_ptr<ParticleCellAssociation >>. where the key is the value of IParticle::index()

This method adds the ParticleCellAssociation to the cache look-up table which retains ownership.
