Package org.jdbi.v3.sqlobject.transaction

Interface Transactional<This extends Transactional<This>>

Type Parameters:
This - must match the interface that is extending this one.
All Superinterfaces:
SqlObject
public interface Transactional<This extends Transactional<This>> extends SqlObject
A mixin interface to expose transaction methods on the sql object.

Use caution with on-demand Transactional instances. Handle throws TransactionException if closed while a transaction is open. Since on-demand extensions open and close a handle around each method invocation, calling begin() on an on-demand Transactional will always leave a transaction open, and thus always throw this exception.

Users of on-demand Transactional instances should use the inTransaction and useTransaction methods to execute transactions. It is safe to call other Transactional methods from inside these callbacks.
