Method Detail

deepCopyNotNull

public final Object deepCopyNotNull(Object value)
                             throws HibernateException

Specified by:

deepCopyNotNull in class NullableType

Throws:

HibernateException

---

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

---

hasNiceEquals

public boolean hasNiceEquals()

Description copied from interface: Type

Does this type implement a well-behaved equals() method. (ie. one that is consistent with Type.equals().) Strictly, if this method returns true then x.equals(y) implies Type.equals(x, y) and also Type.equals(x, y) implies that probably x.equals(y)

See Also:

Object.equals(java.lang.Object), Type.equals(java.lang.Object, java.lang.Object)

copy

public Object copy(Object original,
                   Object target,
                   SessionImplementor session,
                   Object owner,
                   Map copiedAlready)
            throws HibernateException

Specified by:

copy in interface Type

Overrides:

copy in class AbstractType

Throws:
