Detailed Description

Implementation of CaloRecHitMetaCollectionV which internally stores a vector of const CaloRecHit pointers. Fast for access and relatively fast to build, but uses more memory than CaloRecHitMetaCollectionCompact.

Appropriate class for subcollections produced by selection algorithms.
