canDirtyCheck

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

从接口复制的说明: 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.

指定者:

canDirtyCheck 在接口中 CustomEntityDirtinessStrategy

参数:

entity - The entity to be check.

persister - The persister corresponding to the given entity

session - The session from which this check originates.

返回:

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

isDirty

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

从接口复制的说明: 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

指定者:

isDirty 在接口中 CustomEntityDirtinessStrategy

参数:

entity - The entity to check.

persister - The persister corresponding to the given entity

session - The session from which this check originates.

返回:

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

resetDirty

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

从接口复制的说明: 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.

指定者:

resetDirty 在接口中 CustomEntityDirtinessStrategy

参数:

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)

从接口复制的说明: 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.

指定者:

findDirty 在接口中 CustomEntityDirtinessStrategy

参数:

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
