Abstract methods

def debugListUserRecords()(implicit tx: T): Seq[Ident[T]]
def numRecords(implicit tx: T): Int

Reports the current number of records stored in the database.

Reports the current number of records stored in the database.

def numUserRecords(implicit tx: T): Int

Reports the current number of user records stored in the database. That is the number of records minus those records used for database maintenance.

Reports the current number of user records stored in the database. That is the number of records minus those records used for database maintenance.

Inherited methods

def close(): Unit

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.

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 init argument, if no root has been stored yet.

def step[A](fun: Tx => A): A

Issues a new transaction (executor), runs the function argument on it, and returns the result.

def stepTag[A](systemTimeNanos: Long)(fun: Tx => 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.

Value Params
systemTimeNanos

Time in nano-seconds since midnight, January 1, 1970 UTC. E.g. System.currentTimeMillis() * 1000000000L (possibly adding nano-seconds fraction).
