package org.springframework.orm.jpa.persistenceunit;
import javax.persistence.spi.PersistenceUnitInfo;
Interface that defines an abstraction for finding and managing JPA PersistenceUnitInfos. Used by LocalContainerEntityManagerFactoryBean
in order to obtain a PersistenceUnitInfo
for building a concrete EntityManagerFactory
. Obtaining a PersistenceUnitInfo instance is an exclusive process.
A PersistenceUnitInfo instance is not available for further calls
anymore once it has been obtained.
