Method Summary

Modifier and TypeMethod and Description
public Object[]

Returns:

The assembled state
assemble(final Object
The entity instance
instance, final Serializable
The entity identifier
id, final EntityPersister
The entity persister
persister, final Interceptor
(currently unused)
interceptor, final EventSource
The session
session)

Deprecated as a consequence of EventSource being deprecated.
Assemble the previously disassembled state represented by this entry into the given entity instance.
public Serializable[]
getDisassembledState()

Implements org.hibernate.cache.spi.entry.CacheEntry.getDisassembledState.

Get the underlying disassembled state todo : this was added to support initializing an entity's EntityEntry snapshot during reattach; this should be refactored to instead expose a method to assemble an EntityEntry based on this state for return.
public String
getSubclass()

Implements org.hibernate.cache.spi.entry.CacheEntry.getSubclass.

Hibernate stores all entries pertaining to a given entity hierarchy in a single region.
public Object
getVersion()

Implements org.hibernate.cache.spi.entry.CacheEntry.getVersion.

Retrieves the version (optimistic locking) associated with this cache entry.
public boolean

Returns:

true/false
isDeepCopyNeeded()

After assembly, is a copy of the array needed?

public boolean
isReferenceEntry()

Implements org.hibernate.cache.spi.entry.CacheEntry.isReferenceEntry.

Does this entry represent a direct entity reference (rather than disassembled state)?
public String
toString()

Overrides java.lang.Object.toString.

Returns a string representation of the object.
Inherited from java.lang.Object:

assembleback to summary
public Object[] assemble(final Object instance, final Serializable id, final EntityPersister persister, final Interceptor interceptor, final EventSource session) throws HibernateException

Deprecated

as a consequence of EventSource being deprecated. See corresponding docs for further information.

Assemble the previously disassembled state represented by this entry into the given entity instance. Additionally manages the PreLoadEvent callbacks.

Parameters
instance:Object

The entity instance

id:Serializable

The entity identifier

persister:EntityPersister

The entity persister

interceptor:Interceptor

(currently unused)

session:EventSource

The session

Returns:Object[]

The assembled state

Exceptions
HibernateException:
Indicates a problem performing assembly or calling the PreLoadEventListeners.
