io.micronaut.transaction

Interface TransactionStatus<T>

Type Parameters:

T - The native transaction type

All Superinterfaces:

java.io.Flushable, SavepointManager, TransactionExecution

All Known Implementing Classes:

AbstractTransactionStatus, DefaultTransactionStatus

public interface TransactionStatus<T>
extends TransactionExecution, SavepointManager, java.io.Flushable

NOTICE: This is a fork of Spring's TransactionStatus modernizing it to use enums, Slf4j and decoupling from Spring. Representation of the status of a transaction.

Transactional code can use this to retrieve status information, and to programmatically request a rollback (instead of throwing an exception that causes an implicit rollback).

Includes the SavepointManager interface to provide access to savepoint management facilities. Note that savepoint management is only available if supported by the underlying transaction manager.

Method Detail

hasSavepoint

boolean hasSavepoint()

Return whether this transaction internally carries a savepoint, that is, has been created as nested transaction based on a savepoint.

This method is mainly here for diagnostic purposes, alongside TransactionExecution.isNewTransaction(). For programmatic handling of custom savepoints, use the operations provided by SavepointManager.

Returns:

Whether a save point is present

flush

void flush()

Flush the underlying session to the datastore, if applicable: for example, all affected Hibernate/JPA sessions.

This is effectively just a hint and may be a no-op if the underlying transaction manager does not have a flush concept. A flush signal may get applied to the primary resource or to transaction synchronizations, depending on the underlying resource.

Specified by:

flush in interface java.io.Flushable

getTransaction

@NonNull
java.lang.Object getTransaction()

Returns:

The underlying transaction object.

getConnection

@NonNull
T getConnection()

Returns:

The associated connection.
