towers() [2/2]

CaloTowerStore::tower_subseg_iterator CaloTowerStore::towers

(

const

Return an iterator for looping over all towers defined by the window subseg.

No end iterator is defined; use subseg.size() to tell when to stop the iteration.

The iteration may not be in tower index order. Use the itower() method of the iterator to find the current tower index.

m_entry_index

CxxUtils::CachedValue<std::vector<unsigned short> > CaloTowerStore::m_entry_index

One of these for each entry in m_towers, giving the index of the corresponding entry in m_entries.

This is only needed for the case of iterating over a window; it is otherwise not filled in. Use a CachedValue for thread-safety.
