Method Details

getColumnSpan

public int getColumnSpan(MappingContext mapping)
                  throws MappingException

Description copied from interface: Type

How many columns are used to persist this type?

Always the same as getSqlTypCodes(mappingContext).length.

Specified by:

getColumnSpan in interface Type

Overrides:

getColumnSpan in class OneToOneType

Parameters:

mapping - The mapping Context object MappingContext

Returns:

The number of columns

Throws:

MappingException - Generally indicates an issue accessing the passed mappingContext object.

getSqlTypeCodes

public int[] getSqlTypeCodes(MappingContext mappingContext)
                      throws MappingException

Description copied from interface: Type

Return the JDBC types codes as defined by Types or SqlTypes for the columns mapped by this type.

The number of elements in this array must match the return from Type.getColumnSpan(org.hibernate.engine.spi.Mapping).

Specified by:

getSqlTypeCodes in interface Type

Overrides:

getSqlTypeCodes in class OneToOneType

Parameters:

mappingContext - The mapping context MappingContext :/

Returns:

The JDBC type codes.

Throws:

MappingException - Generally indicates an issue accessing the passed mapping object.

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

disassemble

public Serializable disassemble(Object value,
 SharedSessionContractImplementor session,
 Object owner)
                         throws HibernateException

Description copied from interface: Type

Return a disassembled representation of the object. This is the representation that is stored in the second-level cache.

A reference to an associated entity should be disassembled to its primary key value.

Specified by:

disassemble in interface Type

Overrides:

disassemble in class OneToOneType

Parameters:

value - the value to cache

session - the originating session

owner - optional parent entity object (needed for collections)

Returns:

the disassembled, deep cloned state

Throws:

HibernateException - An error from Hibernate

disassemble

public Serializable disassemble(Object value,
 SessionFactoryImplementor sessionFactory)
                         throws HibernateException

Description copied from interface: Type

Return a disassembled representation of the object. This is the representation that is stored in the second-level cache.

A reference to an associated entity should be disassembled to its primary key value.

A high-quality implementation of this method should ensure that:

 Objects.equals(disassemble(x,s), disassemble(y,s)) == isEqual(x,y,sf)
 

and that:

 Objects.equals(x, assemble(disassemble(x,s),s,o))
 

That is, the implementation must be consistent with Type.isEqual(Object, Object, SessionFactoryImplementor) and with Type.assemble(Serializable, SharedSessionContractImplementor, Object).

Specified by:

disassemble in interface Type

Overrides:

disassemble in class OneToOneType

Parameters:

value - the value to cache

sessionFactory - the session factory

Returns:

the disassembled, deep cloned state

Throws:

HibernateException - An error from Hibernate

assemble

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

Description copied from interface: Type

Reconstruct the object from its disassembled state. This function is the inverse of Type.disassemble(Object, SharedSessionContractImplementor, Object).

Specified by:

assemble in interface Type

Overrides:

assemble in class OneToOneType

Parameters:

oid - the disassembled state from the cache

session - the originating session

owner - the parent entity object

Returns:

the (re)assembled object

Throws:

HibernateException - An error from Hibernate
