IdentifierMap

trait IdentifierMap[Id, -Tx, A] extends Disposable[Tx]

An identifier map is basically a transactional map whose keys are system identifiers. However, there are two important aspects: First, the map is always ephemeral (but might be still durable!), even for a confluently persistent system. Second, for systems whose identifiers constitute temporal traces (confluently persistent system), lookup (via get, contains etc.) finds _any_ value stored for the current version or any older version. That is to say, in a confluently persistent system, it looks up the most recent entry for the key. It is therefore a useful tool to map system entities to ephemeral live views.

Id

the underlying system's identifier type

Tx

the underlying system's transaction type

A

the values stored at the keys. Unit can be used if only set functionality is needed.
