                throws HibernateException

Description copied from interface: Type

Return a deep copy of the persistent state, stopping at entities and at collections.

Specified by:

deepCopy in interface Type

Parameters:

value - generally a collection element or entity field

Returns:

Object a copy

Throws:

Description copied from interface: CompositeType

Is the given method a member of this component's class?

Specified by:

Has the value been modified compared to the current database state? The difference between this and the Type.isDirty(java.lang.Object, java.lang.Object, org.hibernate.engine.SessionImplementor) methods is that here we need to account for "partially" built values. This is really only an issue with association types.

Specified by:

isModified in interface Type

Overrides:

isModified in class AbstractType
