persistence provider when creating an EntityManagerFactory
.
Method Summary | |
---|---|
void |
addTransformer(ClassTransformer transformer)
Add a transformer supplied by the provider that will be called for every new class definition or class redefinition that gets loaded by the loader returned by the PersistenceUnitInfo#getClassLoader method. |
boolean |

getValidationMode()
Returns the validation mode to be used by the persistence provider for the persistence unit. |
Method Detail |
---|
java.lang.String getPersistenceUnitName()
name
attribute in the persistence.xml file.
- Returns:
- the name of the persistence unit
java.lang.String getPersistenceProviderClassName()
provider
element in
the persistence.xml
file.
PersistenceUnitTransactionType getTransactionType()
EntityManagerFactory
. The transaction type corresponds to
the transaction-type
attribute in the persistence.xml
file.
javax.sql.DataSource getJtaDataSource()
jta-data-source
element in the persistence.xml
file or is
provided at deployment or by the container.
javax.sql.DataSource getNonJtaDataSource()
non-jta-data-source
element in the persistence.xml
file or
provided at deployment or by the container.
java.util.List<java.lang.String> getMappingFileNames()
mapping-file
element in the
persistence.xml
file.
java.util.List<java.net.URL> getJarFileUrls()
jar-file
element in the
persistence.xml
file. A URL will either be a
file: URL referring to a jar file or referring to a directory
that contains an exploded jar file, or some other URL from
which an InputStream in jar format can be obtained.
java.net.URL getPersistenceUnitRootUrl()
java.util.List<java.lang.String> getManagedClassNames()
class
element in the
persistence.xml
file.
boolean excludeUnlistedClasses()
exclude-unlisted-classes
element in the persistence.xml
file.
SharedCacheMode getSharedCacheMode()
shared-cache-mode
element in the persistence.xml
file.
ValidationMode getValidationMode()
validation-mode
element in the
persistence.xml
file.
java.util.Properties getProperties()
property
element in the persistence.xml
file.
java.lang.String getPersistenceXMLSchemaVersion()
persistence.xml
file.
java.lang.ClassLoader getClassLoader()
void addTransformer(ClassTransformer transformer)
PersistenceUnitInfo#getClassLoader
method. The transformer
has no effect on the result returned by the
PersistenceUnitInfo#getNewTempClassLoader
method.
Classes are only transformed once within the same classloading
scope, regardless of how many persistence units they may be
a part of.
transformer
- provider-supplied transformer that the
container invokes at class-(re)definition timejava.lang.ClassLoader getNewTempClassLoader()
PersistenceUnitInfo#getClassLoader
. None of the classes loaded
by this class loader will be visible to application
components. The provider may only use this ClassLoader within
the scope of the PersistenceProvider#createContainerEntityManagerFactory
call.
