Class MutableType
- Serializable, Type
public abstract class MutableType
Superclass for mutable nullable types
Object | deepCopy(Object value, EntityMode entityMode, SessionFactoryImplementor factory) - Return a deep copy of the persistent state, stopping at entities and at
collections.
|
protected abstract Object | deepCopyNotNull(Object value)
|
boolean | isMutable() - Are objects of this type mutable.
|
Object | replace(Object original, Object target, SessionImplementor session, Object owner, Map copyCache) - During merge, replace the existing (target) value in the entity we are merging to
with a new (original) value from the detached entity we are merging.

isMutable
public final boolean isMutable()
Are objects of this type mutable. (With respect to the referencing object ...
entities and collections are considered immutable because they manage their
own internal state.)

Object owner,
Map copyCache)
throws HibernateException
During merge, replace the existing (target) value in the entity we are merging to
with a new (original) value from the detached entity we are merging. For immutable
objects, or null values, it is safe to simply return the first parameter. For
mutable objects, it is safe to return a copy of the first parameter. For objects
with component values, it might make sense to recursively replace component values.

original
- the value from the detached entity being mergedtarget
- the value in the managed entity
