Package jakarta.persistence.spi

package jakarta.persistence.spi

Defines an SPI for integrating with the persistence provider and with the Jakarta EE platform.

• PersistenceProvider must be implemented by every persistence provider.
• ClassTransformer allows the persistence provider to peform its own custom bytecode processing in a Jakarta EE environment.
• PersistenceUnitInfo carries information about a persistence unit under the management of the Jakarta EE container.
• The Discoverable meta-annotation identifies annotation types which trigger automatic discovery of classes by the Jakarta EE container.
