Method Detail

close

void close()

Close the factory, releasing any resources that it holds. After a factory instance has been closed, all methods invoked on it will throw the IllegalStateException, except for isOpen, which will return false. Once an EntityManagerFactory has been closed, all its entity managers are considered to be in the closed state.

Throws:

IllegalStateException - if the entity manager factory has been closed

createEntityManager

EntityManagerLite createEntityManager()

Create a new application-managed EntityManager. This method returns a new EntityManager instance each time it is invoked. The isOpen method will return true on the returned instance.

Returns:

entity manager instance

Throws:

IllegalStateException - if the entity manager factory has been closed

createEntityManager

EntityManagerLite createEntityManager(Map<String,Object> map)

Create a new application-managed EntityManager with the specified Map of properties. This method returns a new EntityManager instance each time it is invoked. The isOpen method will return true on the returned instance.

Parameters:

map - properties for entity manager

Returns:

entity manager instance

Throws:

IllegalStateException - if the entity manager factory has been closed

getProperties

Map<String,Object> getProperties()

Get the properties and associated values that are in effect for the entity manager factory. Changing the contents of the map does not change the configuration in effect.

Returns:

properties

isOpen

boolean isOpen()

Indicates whether the factory is open. Returns true until the factory has been closed.

Returns:

boolean indicating whether the factory is open
