Method Detail

deepCopy

public final Object deepCopy(Object value,
                             EntityMode entityMode,
                             SessionFactoryImplementor factory)
Description copied from interface: Type
Return a deep copy of the persistent state, stopping at entities and at collections.

Parameters:
value - generally a collection element or entity field
Returns:
Object a copy

isMutable

public final boolean isMutable()
Description copied from interface: Type
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.)

Returns:
boolean

replace

public Object replace(Object original,
                      Object target,
                      SessionImplementor session,
                      Object owner,
                      Map copyCache)
               throws HibernateException
Description copied from interface: Type
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.

Parameters:
original - the value from the detached entity being merged
target - the value in the managed entity
Returns:
the value to be merged
Throws:
HibernateException
