Typedef Documentation

IndexMultimap

template<typename Value , typename Key = std::size_t>

using FW::IndexMultimap = typedef boost::container::flat_multimap<Key, Value>

Store elements that are identified by an index, e.g. in another container.

Each index can have zero or more associated elements. A typical case could be to store all generating particles for a hit where the hit is identified by its index in the hit container.

ProtoTrack

using FW::ProtoTrack = typedef std::vector<size_t>

A proto track is a collection of hits identified by their indices.

ProtoTrackContainer

using FW::ProtoTrackContainer = typedef std::vector<ProtoTrack>

Container of proto tracks. Each proto track is identified by its index.

Function Documentation

invertIndexMultimap()

template<typename Value , typename Key >

IndexMultimap< Key, Value > FW::invertIndexMultimap ( const IndexMultimap< Value, Key > &  multimap )

inline

Invert the multimap, i.e. from a -> {b...} to b -> {a...}.

Note

This assumes that the value in the initial multimap is itself a sortable index-like object, as would be the case when mapping e.g. hit ids to particle ids/ barcodes.
