Detailed Description

The purpose of the Store object is to act as a "particle manager" that keeps track ofall the particles in our simulation. It also tracks the avatars and their connections to particles.

void G4INCL::Store::add

(

Particle *

p

)

Add one particle to the store.

Particle objects don't know anything about avatars so this method will only do two things:

1. add the particle to the particle map ParticleID -> Particle*
2. add an empty entry for this particle into map AvatarID -> [ParticleID]

Definition at line 58 of file G4INCLStore.cc.

                             {
    inside.push_back(p);
  }

Here is the caller graph for this function:

void G4INCL::Store::add

(

ParticleList const &

pL

)

Add a list of particles to the Store.

This acts as if add(Particle *) was called on each element of the list.

Definition at line 62 of file G4INCLStore.cc.

                                        {
    inside.insert(inside.end(), pL.begin(), pL.end());
  }

void G4INCL::Store::add

(

IAvatar *

a

)

Add one avatar to the store

Avatars know about the particles they are associated with. Adding an avatar consists of the following steps:

1. Add the new avatar to the avatar list
2. Add any related new particles to the store by calling add(Particle*) (this should not happen, by the time we are adding avatars all particles should have already been added)
3. Connect the particles involved to the avatar in the map: particleAvatarConnections :: ParticleID -> [AvatarID]
4. Add the new avatar to the map: avatarParticleConnections :: AvatarID -> [ParticleID]

Definition at line 83 of file G4INCLStore.cc.

                            {
    // Add the avatar to the avatar map
    avatarList.push_back(a);

    for(ParticleIter i=pList.begin(), e=pList.end(); i!=e; ++i) {
      // Connect each particle to the avatar
      connectAvatarToParticle(a, *i);
    }

  }

void G4INCL::Store::addIncomingParticle
