Also, if these IntBags are really “artifacts” owned or possessed by “agents”, they why not create separate objects called Artifacts or equivalent? Each artifact would have variable of type Agent to identify it’s owner -- a single agent. Each agent would have a bag of “myArtifacts”. Upon request from another agent, the owner agent could transferOwnership() of the requested artifact, removing it from its own myArtifacts bag, and by calling a method in the artifact object: changeOwner(newAgentID). The artifact object could then signal completion of the transaction by calling addNewArtifact() method in the requesting agent, which would add it to myArtifacts.
