Constructor Detail

### SpecialOneToOneType

    public SpecialOneToOneType(String referencedEntityName,
                               ForeignKeyDirection foreignKeyType,
                               String uniqueKeyPropertyName,
                               boolean lazy,
                               boolean unwrapProxy,
                               String entityName,
                               String propertyName)

Method Detail

### getColumnSpan

    public int getColumnSpan(Mapping mapping)
                      throws MappingException

  Description copied from interface: `Type`
  How many columns are used to persist this type.

  Specified by:
    `getColumnSpan` in interface `Type`
  Overrides:
    `getColumnSpan` in class `OneToOneType`
  Throws:
    `MappingException`

### sqlTypes

    public int[] sqlTypes(Mapping mapping)
                   throws MappingException

  Description copied from interface: `Type`
  Return the SQL type codes for the columns mapped by this type. The codes are defined on `java.sql.Types`.

  Specified by:
    `sqlTypes` in interface `Type`
  Overrides:
    `sqlTypes` in class `OneToOneType`
  Returns:
    the typecodes
  Throws:
    `MappingException`
  See Also:
    `Types`

### useLHSPrimaryKey

    public boolean useLHSPrimaryKey()

  Description copied from interface: `AssociationType`
  Is the primary key of the owning entity table to be used in the join?

  Specified by:
    `useLHSPrimaryKey` in interface `AssociationType`
  Overrides:
    `useLHSPrimaryKey` in class `OneToOneType`

### hydrate

    public Object hydrate(ResultSet rs,
                          String[] names,

                   throws HibernateException,
                          SQLException

  Description copied from interface: `Type`
  Retrieve an instance of the mapped class, or the identifier of an entity or collection, from a JDBC resultset. This is useful for 2-phase property initialization - the second phase is a call to `resolveIdentifier()`.

  Specified by:
    `hydrate` in interface `Type`
  Overrides:
    `hydrate` in class `OneToOneType`
    `names` - the column names
    `session` - the session
    `owner` - the parent entity
  Returns:
    Object an identifier or actual value
  Throws:
    `HibernateException`
    `SQLException`
  See Also:
    `Type.resolve(Object, SessionImplementor, Object)`

### disassemble

                             throws HibernateException

  Description copied from interface: `Type`
  Return a cacheable "disassembled" representation of the object.

  Specified by:
    `disassemble` in interface `Type`
  Overrides:
    `disassemble` in class `OneToOneType`
  Parameters:
    `value` - the value to cache
    `session` - the session
    `owner` - optional parent entity object (needed for collections)
  Returns:
    the disassembled, deep cloned state
  Throws:
    `HibernateException`

### assemble

    public Object assemble(Serializable oid,
                           SessionImplementor session,
                           Object owner)
                    throws HibernateException

  Description copied from interface: `Type`
  Reconstruct the object from its cached "disassembled" state.

  Specified by:
    `assemble` in interface `Type`
  Overrides:
    `assemble` in class `OneToOneType`
  Parameters:
    `oid` - the disassembled state from the cache
    `session` - the session
    `owner` - the parent entity object
  Returns:
    the the object
  Throws:
    `HibernateException`
