Method Detail

initialize

public static void initialize()

getDefaultFactory

public static EntityManagerFactory getDefaultFactory()

setDefaultFactory

public static void setDefaultFactory(EntityManagerFactory defaultFactory)

registerQueryProcessor

public static void registerQueryProcessor(QueryProcessor processor)

processorForQuery

public QueryProcessor processorForQuery(QuerySpecification spec)

Specified by:

processorForQuery in class ObjectContext

merge

public <T> T merge(T t)

Specified by:

merge in class ObjectContext

remove

public void remove(Object o)

Specified by:

remove in class ObjectContext

find

public <T> T find(Class<T> tClass,
                  Object primaryKey)

Specified by:

find in class ObjectContext

recordForInsert

public void recordForInsert(Object o)

Description copied from class: ObjectContext

Records object for insert on next save(). Some contexts may persist here, others may defer the persist until just pre-save, to give the newly created object a change to be fully initialized prior to persist()

Overrides:

recordForInsert in class ObjectContext

Parameters:

o - object instance to be inserted

save

public void save()

Specified by:

save in class ObjectContext

createNestedContext

public ObjectContext createNestedContext()

NOTE: this implementation is currently BROKEN! The JPA EntityManager API does not include support for nested EntityManagers, and this attempt to emulate from the outside (including using Hibernate interceptor APIs) does not work completely (do to issues with applying merge() when saving back unsaved objects from the child back to the parent).

Overrides:

createNestedContext in class ObjectContext

Returns:

the new child context instance

isTransient

public Boolean isTransient(Object o)

lock

public void lock(Object o)

Specified by:

lock in class ObjectContext

contains

public boolean contains(Object o)

Specified by:

contains in class ObjectContext

executeNamedQuery

public List executeNamedQuery(String s,
                              Map<String,Object> params)

Specified by:

executeNamedQuery in class ObjectContext

getDelegate

public Object getDelegate()

Specified by:

getDelegate in class ObjectContext

getJPAEntityManager

public EntityManager getJPAEntityManager()
