EntityManagerFactoryBuilder (OSGi Compendium Release 6)

```
public interface EntityManagerFactoryBuilder
```
This service interface offers JPA clients the ability to create instances of EntityManagerFactory for a given named persistence unit. A service instance will be created for each named persistence unit and can be filtered by comparing the value of the osgi.unit.name property containing the persistence unit name. This service is used specifically when the caller wants to pass in factory-scoped properties as arguments. If no properties are being used in the creation of the EntityManagerFactory then the basic EntityManagerFactory service should be used.
