 It is invoked by the container in Java EE environments and
 by the Persistence class in Java SE environments to
 create an EntityManagerFactory and/or to cause
 schema generation to occur.

EntityManagerFactory createEntityManagerFactory(String emName, Map map)
Persistence class when an
 EntityManagerFactory is to be created.emName - the name of the persistence unitmap - a Map of properties for use by the 
 persistence provider. These properties may be used to
 override the values of the corresponding elements in 
 the persistence.xml file or specify values for 
 properties not specified in the persistence.xml
 (and may be null if no properties are specified).EntityManagerFactory createContainerEntityManagerFactory(PersistenceUnitInfo info, Map map)
EntityManagerFactory
 is to be created.info - metadata for use by the persistence providermap - a Map of integration-level properties for use 
 by the persistence provider (may be null if no properties
 are specified).  These properties may include properties to
 control schema generation.
 If a Bean Validation provider is present in the classpath,
 the container must pass the ValidatorFactory instance in
 the map with the key "javax.persistence.validation.factory".
 If the containing archive is a bean archive, the container
 must pass the BeanManager instance in the map with the key
 "javax.persistence.bean.manager".void generateSchema(PersistenceUnitInfo info, Map map)
Called by the container when schema generation is to occur as a separate phase from creation of the entity manager factory.
info - metadata for use by the persistence providermap - properties for schema generation;  these may
             also include provider-specific propertiesPersistenceException - if insufficient or inconsistent

Called by the Persistence class when schema generation is to occur as a separate phase from creation of the entity manager factory.
persistenceUnitName - the name of the persistence unitmap - properties for schema generation;  these may
             also contain provider-specific properties.  The
             value of these properties override any values that
             may have been configured elsewhere.PersistenceException - if insufficient or inconsistent
