getVersion

public Object getVersion()

Specified by:

getVersion in interface EntityEntry

postInsert

public void postInsert(Object version)

Specified by:

postInsert in interface EntityEntry

getPersister

public EntityPersister getPersister()

Specified by:

getPersister in interface EntityEntry

getEntityKey

public EntityKey getEntityKey()

Description copied from interface: EntityEntry

Get the EntityKey for this entry.

Specified by:

getEntityKey in interface EntityEntry

Returns:

the EntityKey

getEntityName

public String getEntityName()

Specified by:

getEntityName in interface EntityEntry

isBeingReplicated

public boolean isBeingReplicated()

Specified by:

isBeingReplicated in interface EntityEntry

getRowId

public Object getRowId()

Specified by:

getRowId in interface EntityEntry

postUpdate

public void postUpdate(Object entity,
 Object[] updatedState,
 Object nextVersion)

Description copied from interface: EntityEntry

Handle updating the internal state of the entry after actually performing the database update. Specifically, we update the snapshot information and escalate the lock mode.

Specified by:

postUpdate in interface EntityEntry

Parameters:

entity - The entity instance

updatedState - The state calculated after the update (becomes the new loaded state.

nextVersion - The new version.

postLoad

public void postLoad(Object entity)

Specified by:

postLoad in interface EntityEntry

postDelete

public void postDelete()

Description copied from interface: EntityEntry

After actually deleting a row, record the fact that the instance no longer exists in the database.

Specified by:

postDelete in interface EntityEntry

postInsert

public void postInsert(Object[] insertedState)

Description copied from interface: EntityEntry

After actually inserting a row, record the fact that the instance exists in the database (needed for identity column key generation).

Specified by:

postInsert in interface EntityEntry

isNullifiable

public boolean isNullifiable(boolean earlyInsert,
 SharedSessionContractImplementor session)

Specified by:

isNullifiable in interface EntityEntry

getLoadedValue

public Object getLoadedValue(String propertyName)

Specified by:

getLoadedValue in interface EntityEntry

overwriteLoadedStateCollectionValue

public void overwriteLoadedStateCollectionValue(String propertyName,
 PersistentCollection<?> collection)

Specified by:

overwriteLoadedStateCollectionValue in interface EntityEntry

requiresDirtyCheck

public boolean requiresDirtyCheck(Object entity)

Description copied from interface: EntityEntry

Returns true if the entity can possibly be dirty. This can only be the case if it is in a modifiable state (not read-only nor deleted) and it either has mutable properties or field-interception is not telling us that it is dirty.

Specified by:

requiresDirtyCheck in interface EntityEntry

Parameters:

entity - The entity to test

Returns:

true indicates that the entity could possibly be dirty and that the dirty-check should happen; false indicates there is no way the entity can be dirty

isModifiableEntity

public boolean isModifiableEntity()

Description copied from interface: EntityEntry

Can the entity be modified?

The entity is modifiable if all the following are true:

• the entity class is mutable,
• the entity is not read-only, and
• if the current status is Status.DELETED, then the entity was not read-only when it was deleted.

Specified by:

isModifiableEntity in interface EntityEntry

Returns:

true, if the entity is modifiable; false, otherwise,

forceLocked

public void forceLocked(Object entity,
 Object nextVersion)

Specified by:

forceLocked in interface EntityEntry

isReadOnly

public boolean isReadOnly()

Specified by:

isReadOnly in interface EntityEntry

setReadOnly

public void setReadOnly(boolean readOnly,
 Object entity)

Specified by:

setReadOnly in interface EntityEntry

getMaybeLazySet

public @Nullable ImmutableBitSet getMaybeLazySet()

Description copied from interface: EntityEntry

Has a bit set for every attribute position that is potentially lazy. When null, no knowledge is available and every attribute must be assumed potentially lazy.

Specified by:

getMaybeLazySet in interface EntityEntry

setMaybeLazySet

public void setMaybeLazySet(@Nullable ImmutableBitSet maybeLazySet)

Specified by:

setMaybeLazySet in interface EntityEntry

toString in interface EntityEntry

Overrides:

toString in class Object

serialize

               throws IOException

Description copied from interface: EntityEntry

Custom serialization routine used during serialization of a Session/PersistenceContext for increased performance.

Specified by:
