Abstract Value Members
- abstract def close(): Unit
Closes the underlying database (if the system is durable).
Closes the underlying database (if the system is durable). The STM cannot be used beyond this call. An in-memory system should have a no-op implementation.

- abstract def numUserRecords(implicit tx: T): Int
Reports the current number of user records stored in the database.
Reports the current number of user records stored in the database. That is the number of records minus those records used for database maintenance.

- abstract def root[A](init: (T) => A)(implicit format: TFormat[T, A]): Source[T, A]
Reads the root object representing the stored data structure, or provides a newly initialized one via the
initargument, if no root has been stored yet.Reads the root object representing the stored data structure, or provides a newly initialized one via the

- abstract def step[A](fun: (Durable.Txn) => A): A
Issues a new transaction (executor), runs the function argument on it, and returns the result.

- abstract def stepTag[A](systemTimeNanos: Long)(fun: (Durable.Txn) => A): A
Issues a new transaction (executor), tagged with the given time referring to "now", runs the function argument on it, and returns the result.
Issues a new transaction (executor), tagged with the given time referring to "now", runs the function argument on it, and returns the result.
The tagging can be used for latency based circumstances, such as scheduling OSC bundles on a sound server.
- systemTimeNanos
Time in nano-seconds since midnight, January 1, 1970 UTC. E.g.
System.currentTimeMillis() * 1000000000L(possibly adding nano-seconds fraction).
