type
Acc = Unit
The path access type for objects if they carry a temporal trace.
The path access type for objects if they carry a temporal trace. This is used by confluently persistent systems, while it is typically
Unitfor ephemeral systems.- Definition Classes

final
type
Id = lucre.stm.DurableLike.Id[Durable]
The identifier type of the system.
The identifier type of the system. This is an opaque type about which the user only knows that it uniquely identifies and object (or an object along with its access path in the confluent case). It is thus valid to assume that two objects are equal if their identifiers are equal.

type
Var[A] = lucre.stm.Var[Tx, A]
The variable type of the system.
The variable type of the system. Variables allow transactional storage and retrieval both of immutable and mutable values. Specific systems may extend the minimum capabilities described by the
Vartrait.- Definition Classes

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.

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).
