`SessionBroker`	`getSessionBroker()`	Returns the SessionBroker that the Factory will be using and initializes it if it is not available.
`void`	`refreshMetadata(java.util.Map<java.lang.String,java.lang.Object> properties)`	As this EntityManagerFactory to refresh itself.

- Method Detail
  - getDatabaseSession
```
org.eclipse.persistence.internal.sessions.DatabaseSessionImpl getDatabaseSession()
```
    Returns the DatabaseSession that the Factory will be using and initializes it if it is not available.
  - getServerSession
```
ServerSession getServerSession()
```
    Returns the ServerSession that the Factory will be using and initializes it if it is not available.
  - getSessionBroker
```
SessionBroker getSessionBroker()
```
    Returns the SessionBroker that the Factory will be using and initializes it if it is not available. Calls to this method should only be made on entity managers representing composite persistence units.
  - unwrap
```
org.eclipse.persistence.internal.jpa.EntityManagerFactoryDelegate unwrap()
```
    Gets the underlying implementation of the EntityManagerFactory. This method will return a version of EntityManagerFactory that is based on the available metadata at the time it is called. Future calls to refresh will not affect that metadata on this EntityManagerFactory.
    
    Returns:
  - refreshMetadata
```
void refreshMetadata(java.util.Map<java.lang.String,java.lang.Object> properties)
```
    As this EntityManagerFactory to refresh itself. This will cause the underlying EntityManagerFactory implementation to be dropped and a new one to be bootstrapped. Existing EntityManagers will continue to use the old implementation
