Durable

Type Members

final 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 Unit for ephemeral systems.

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.

final type Tx = Txn

The transaction type of the system.
The transaction type of the system.

final 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 Var trait.

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.
