abstract def newHandle[A](value: A)(implicit serializer: Serializer[S.Tx, S.Acc, A]): Source[S.Tx, A]

Creates a handle (in-memory) to refresh a stale version of an object, assuming that the future transaction is issued from the same cursor that is used to create the handle, except for potentially having advanced.
Creates a handle (in-memory) to refresh a stale version of an object, assuming that the future transaction is issued from the same cursor that is used to create the handle, except for potentially having advanced. This is a mechanism that can be used in live views to gain valid access to a referenced object (e.g. self access).

the object which will be refreshed when calling get on the returned handle

used to write and freshly read the object
returns
the handle
abstract def newID(): S.ID
abstract def newInMemoryIDMap[A]: IdentifierMap[S.ID, S.Tx, A]

Creates a new in-memory transactional map for storing and retrieving values based on a mutable's identifier as key.
Creates a new in-memory transactional map for storing and retrieving values based on a mutable's identifier as key. If a system is confluently persistent, the get operation will find the most recent key that matches the search key. Objects are not serialized but kept live in memory.
ID maps can be used by observing views to look up associated view meta data even though they may be presented with a more recent access path of the model peer (e.g. when a recent event is fired and observed).
A
the value type in the map

Every transaction has a plain Scala-STM transaction as a peer.
Every transaction has a plain Scala-STM transaction as a peer. This comes handy for setting up custom things like TxnLocal, TMap, or calling into the hooks of concurrent.stm.Txn. It is also needed when re-wrapping the transaction of one system into another.
