Interface ManagedEntity

All Superinterfaces:

Managed, PrimeAmongSecondarySupertypes

public interface ManagedEntity
extends Managed

Specialized Managed contract for entity classes. Essentially provides access to information about an instance's association to a Session/EntityManager. Specific information includes:

• the association's EntityEntry (by way of $$_hibernate_getEntityEntry() and $$_hibernate_setEntityEntry(org.hibernate.engine.spi.EntityEntry)). EntityEntry describes states, snapshots, etc.
• link information. ManagedEntity instances are part of a "linked list", thus link information describes the next and previous entries/nodes in that ordering. See $$_hibernate_getNextManagedEntity(), $$_hibernate_setNextManagedEntity(org.hibernate.engine.spi.ManagedEntity), $$_hibernate_getPreviousManagedEntity(), $$_hibernate_setPreviousManagedEntity(org.hibernate.engine.spi.ManagedEntity)

Method Summary

Modifier and Type	Method	Description
EntityEntry	$$_hibernate_getEntityEntry()	Provides access to the associated EntityEntry.
Object	$$_hibernate_getEntityInstance()	Obtain a reference to the entity instance.
ManagedEntity	$$_hibernate_getNextManagedEntity()	Part of entry linking; obtain reference to the next entry.
ManagedEntity	$$_hibernate_getPreviousManagedEntity()	Part of entry linking; obtain reference to the previous entry.
void	$$_hibernate_setEntityEntry(EntityEntry entityEntry)	Injects the EntityEntry associated with this entity instance.
void	$$_hibernate_setNextManagedEntity(ManagedEntity next)	Part of entry linking; sets the next entry.
void	$$_hibernate_setPreviousManagedEntity(ManagedEntity previous)	Part of entry linking; sets the previous entry.
void	$$_hibernate_setUseTracker(boolean useTracker)	Used to understand if the tracker can be used to detect dirty properties.
boolean	$$_hibernate_useTracker()	Can the tracker be used to detect dirty attributes

Method Details

$$_hibernate_getEntityInstance

Object $$_hibernate_getEntityInstance()

Obtain a reference to the entity instance.

Returns:

The entity instance.

$$_hibernate_getEntityEntry

EntityEntry $$_hibernate_getEntityEntry()

Provides access to the associated EntityEntry.

Returns:

The EntityEntry associated with this entity instance.

See Also:

• $$_hibernate_setEntityEntry(org.hibernate.engine.spi.EntityEntry)

$$_hibernate_setEntityEntry

void $$_hibernate_setEntityEntry(EntityEntry entityEntry)

Injects the EntityEntry associated with this entity instance. The EntityEntry represents state associated with the entity in regards to its association with a Hibernate Session.

Parameters:

entityEntry - The EntityEntry associated with this entity instance.

$$_hibernate_getPreviousManagedEntity

ManagedEntity $$_hibernate_getPreviousManagedEntity()

Part of entry linking; obtain reference to the previous entry. Can be null, which should indicate this is the head node.

Returns:

The previous entry

$$_hibernate_setPreviousManagedEntity

void $$_hibernate_setPreviousManagedEntity(ManagedEntity previous)

Part of entry linking; sets the previous entry. Again, can be null, which should indicate this is (now) the head node.

Parameters:

previous - The previous entry

$$_hibernate_getNextManagedEntity

ManagedEntity $$_hibernate_getNextManagedEntity()

Part of entry linking; obtain reference to the next entry. Can be null, which should indicate this is the tail node.

Returns:

The next entry

$$_hibernate_setNextManagedEntity

void $$_hibernate_setNextManagedEntity(ManagedEntity next)

Part of entry linking; sets the next entry. Again, can be null, which should indicate this is (now) the tail node.

Parameters:

next - The next entry

$$_hibernate_setUseTracker

void $$_hibernate_setUseTracker(boolean useTracker)

Used to understand if the tracker can be used to detect dirty properties. E.g:

Parameters:

useTracker - true if the tracker can be used to detect dirty properties, false otherwise

$$_hibernate_useTracker

boolean $$_hibernate_useTracker()

Can the tracker be used to detect dirty attributes

Returns:

true if the tracker can be used to detect dirty properties, false otherwise

asManagedEntity

default ManagedEntity asManagedEntity()

Special internal contract to optimize type checking

Specified by:

asManagedEntity in interface PrimeAmongSecondarySupertypes

Returns:

this same instance
