public void onDelete(Object entity,
                     Serializable id,
                     Object[] state,
                     String[] propertyNames,
                     Type[] types)
```
    从接口复制的说明: Interceptor
    
    Called before an object is deleted. It is not recommended that the interceptor modify the state.
    
    指定者:
    
    onDelete 在接口中 Interceptor
    
    参数:
    
    entity - The entity instance being deleted
    
    id - The identifier of the entity
    
    state - The state of the entity
    
    propertyNames - The names of the entity properties.
    
    types - The types of the entity properties
  - onFlushDirty
```
public boolean onFlushDirty(Object entity,
                            Serializable id,
                            Object[] currentState,
                            Object[] previousState,
                            String[] propertyNames,
                            Type[] types)
```
    从接口复制的说明: Interceptor
    
    Called when an object is detected to be dirty, during a flush. The interceptor may modify the detected currentState, which will be propagated to both the database and the persistent object. Note that not all flushes end in actual synchronization with the database, in which case the new currentState will be propagated to the object, but not necessarily (immediately) to the database. It is strongly recommended that the interceptor not modify the previousState.
    NOTE: The indexes across the currentState, previousState, propertyNames and types arrays match.
    
    指定者:
    
    onFlushDirty 在接口中 Interceptor
    
    参数:
    
    entity - The entity instance detected as being dirty and being flushed
    
    id - The identifier of the entity
    
    currentState - The entity's current state
    
    previousState - The entity's previous (load time) state.
    
    propertyNames - The names of the entity properties
    
    types - The types of the entity properties
    
    返回:
    
    true if the user modified the currentState in any way.
  - onLoad
```
public boolean onLoad(Object entity,

                      Object[] state,
                      String[] propertyNames,
                      Type[] types)
```
    从接口复制的说明: Interceptor
    
    Called just before an object is initialized. The interceptor may change the state, which will be propagated to the persistent object. Note that when this method is called, entity will be an empty uninitialized instance of the class.
    NOTE: The indexes across the state, propertyNames and types arrays match.
    
    指定者:
    
    onLoad 在接口中 Interceptor
    
    参数:
    
    entity - The entity instance being loaded
    
    id - The identifier value being loaded
    
    state - The entity state (which will be pushed into the entity instance)
    
    propertyNames - The names of the entity properties, corresponding to the state.
    
    types - The types of the entity properties, corresponding to the state.
    
    返回:
    
    true if the user modified the state in any way.
  - onSave
```
public boolean onSave(Object entity,
                      Serializable id,
                      Object[] state,
                      String[] propertyNames,
                      Type[] types)
```
    从接口复制的说明: Interceptor
    
    Called before an object is saved. The interceptor may modify the state, which will be used for the SQL INSERT and propagated to the persistent object.
    
    指定者:
    
    onSave 在接口中 Interceptor
    
    参数:
    
    entity - The entity instance whose state is being inserted
    
    id - The identifier of the entity
    
    state - The state of the entity which will be inserted
    
    propertyNames - The names of the entity properties.
    
    types - The types of the entity properties
    
    返回:
    
    true if the user modified the state in any way.
