package org.jooq;
import org.jooq.impl.ThreadLocalTransactionProvider;
An FunctionalInterface
that wraps transactional code.
This callable may depend on captured scope ("context") in order to discover a contextual Configuration
to be used to create new SQL statements. Clients are responsible to implement such context state in appropriate ConnectionProvider
and TransactionProvider
implementations.
An out-of-the-box implementation for a fitting TransactionProvider
is available through ThreadLocalTransactionProvider
.

public interface ContextTransactionalCallable<T> {
Run the transactional code.
If this method completes normally, and this is not a nested transaction, then the transaction will be committed. If this method completes with an exception (any Throwable
), then the transaction is rolled back to the beginning of this ContextTransactionalCallable
.
Throws: - Throwable – Any exception that will cause a rollback of the code
contained in this transaction. If this is a nested
transaction, the rollback may be performed only to the state
before executing this
ContextTransactionalCallable
.
Returns: The outcome of the transaction.
