Method Summary

Modifier and Type	Method and Description
boolean	canDirtyCheck(Object entity, EntityPersister persister, Session session) Is this strategy capable of telling whether the given entity is dirty? A return of true means that CustomEntityDirtinessStrategy.isDirty(java.lang.Object, org.hibernate.persister.entity.EntityPersister, org.hibernate.Session) will be called next as the definitive means to determine whether the entity is dirty.
void	findDirty(Object entity, EntityPersister persister, Session session, CustomEntityDirtinessStrategy.DirtyCheckContext dirtyCheckContext) Callback used to hook into Hibernate algorithm for determination of which attributes have changed.
boolean	isDirty(Object entity, EntityPersister persister, Session session) The callback used by Hibernate to determine if the given entity is dirty.
void	resetDirty(Object entity, EntityPersister persister, Session session) Callback used by Hibernate to signal that the entity dirty flag should be cleared.

canDirtyCheck

public boolean canDirtyCheck(Object entity,
                             EntityPersister persister,
                             Session session)

Description copied from interface: CustomEntityDirtinessStrategy

Is this strategy capable of telling whether the given entity is dirty? A return of true means that CustomEntityDirtinessStrategy.isDirty(java.lang.Object, org.hibernate.persister.entity.EntityPersister, org.hibernate.Session) will be called next as the definitive means to determine whether the entity is dirty.

Specified by:

canDirtyCheck in interface CustomEntityDirtinessStrategy

Parameters:

entity - The entity to be check.

persister - The persister corresponding to the given entity

session - The session from which this check originates.

Returns:

true indicates the dirty check can be done; false indicates it cannot.

isDirty

public boolean isDirty(Object entity,
                       EntityPersister persister,
                       Session session)

Description copied from interface: CustomEntityDirtinessStrategy

The callback used by Hibernate to determine if the given entity is dirty. Only called if the previous CustomEntityDirtinessStrategy.canDirtyCheck(java.lang.Object, org.hibernate.persister.entity.EntityPersister, org.hibernate.Session) returned true

Specified by:

isDirty in interface CustomEntityDirtinessStrategy

Parameters:

entity - The entity to check.

persister - The persister corresponding to the given entity

session - The session from which this check originates.

Returns:

true indicates the entity is dirty; false indicates the entity is not dirty.

resetDirty

public void resetDirty(Object entity,
                       EntityPersister persister,
                       Session session)

Description copied from interface: CustomEntityDirtinessStrategy

Callback used by Hibernate to signal that the entity dirty flag should be cleared. Generally this happens after previous dirty changes were written to the database.

Specified by:

resetDirty in interface CustomEntityDirtinessStrategy

Parameters:

entity - The entity to reset

persister - The persister corresponding to the given entity

session - The session from which this call originates.

findDirty

public void findDirty(Object entity,
                      EntityPersister persister,
                      Session session,
                      CustomEntityDirtinessStrategy.DirtyCheckContext dirtyCheckContext)

Description copied from interface: CustomEntityDirtinessStrategy

Callback used to hook into Hibernate algorithm for determination of which attributes have changed. Applications wanting to hook in to this would call back into the given CustomEntityDirtinessStrategy.DirtyCheckContext.doDirtyChecking(org.hibernate.CustomEntityDirtinessStrategy.AttributeChecker) method passing along an appropriate CustomEntityDirtinessStrategy.AttributeChecker implementation.

Specified by:

findDirty in interface CustomEntityDirtinessStrategy

Parameters:

entity - The entity being checked

persister - The persister corresponding to the given entity

session - The session from which this call originates.

dirtyCheckContext - The callback context
