Detailed Description

Member Typedef Documentation

Key

typedef std::pair< bool, Particles > Key

key for the internal container of this map

.first is a bool which is true, if combination was from the same particle which was primary .second vector of IDs (e.g. PDG or mcParticleIDs)

Definition at line 217 of file observers.cc.

Particles

typedef std::vector<int> Particles

a vector containing IDs

Definition at line 209 of file observers.cc.
