Class UnitManager

java.lang.Object

ru.vyarus.guicey.jdbi3.unit.UnitManager

All Implemented Interfaces:

javax.inject.Provider<org.jdbi.v3.core.Handle>

@Singleton
public class UnitManager
extends java.lang.Object
implements javax.inject.Provider<org.jdbi.v3.core.Handle>

Manages JDBI Handle for current unit of work. This handle must be used by all JDBI proxies. Unit of work is thread-bound (all actions in one thread participate in one unit of work). It is not intended to be used directly (only in really rare cases when manual unit required without opening transaction).

Raw provider may be injected to obtain current handle: @Inject Provider<Handle>. In all other cases transaction annotation must be used to wrap code into unit of work using guice aop.
