Method Detail

getColumnSpan

public int getColumnSpan(Mapping mapping)
                  throws MappingException

Description copied from interface: Type

How many columns are used to persist this type. Always the same as sqlTypes(mapping).length

Specified by:

getColumnSpan in interface Type

Overrides:

getColumnSpan in class OneToOneType

Parameters:

mapping - The mapping object :/

Returns:

The number of columns

Throws:

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

sqlTypes

public int[] sqlTypes(Mapping mapping)
               throws MappingException

Description copied from interface: Type

Return the JDBC types codes (per Types) for the columns mapped by this type.

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

Specified by:

sqlTypes in interface Type

Overrides:

sqlTypes in class OneToOneType

Parameters:

mapping - The mapping object :/

Returns:

The JDBC type codes.

Throws:

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

dictatedSizes

public Size[] dictatedSizes(Mapping mapping)
                     throws MappingException

Description copied from interface: Type

Return the column sizes dictated by this type. For example, the mapping for a char/Character would have a dictated length limit of 1; for a string-based UUID would have a size limit of 36; etc.

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

Specified by:

dictatedSizes in interface Type

Overrides:

dictatedSizes in class OneToOneType

Parameters:

mapping - The mapping object :/

Returns:

The dictated sizes.

Throws:

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

defaultSizes

public Size[] defaultSizes(Mapping mapping)
                    throws MappingException

Description copied from interface: Type

Defines the column sizes to use according to this type if the user did not explicitly say (and if no Type.dictatedSizes(org.hibernate.engine.spi.Mapping) were given).

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

Specified by:

defaultSizes in interface Type

Overrides:

defaultSizes in class OneToOneType

Parameters:

mapping - The mapping object :/

Returns:

The default sizes.

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

hydrate

public Object hydrate(ResultSet rs,
                      String[] names,
                      SharedSessionContractImplementor session,
                      Object owner)
               throws HibernateException,
                      SQLException

Description copied from interface: Type

Extract a value from the JDBC result set. This is useful for 2-phase property initialization - the second phase is a call to Type.resolve(java.lang.Object, org.hibernate.engine.spi.SharedSessionContractImplementor, java.lang.Object) This hydrated value will be either:

• in the case of an entity or collection type, the key
• otherwise, the value itself

Specified by:

hydrate in interface Type

Overrides:

hydrate in class OneToOneType

Parameters:

rs - The JDBC result set

names - the column names making up this type value (use to read from result set)

session - The originating session

owner - the parent entity

Returns:

An entity or collection key, or an actual value.

Throws:

HibernateException - An error from Hibernate

SQLException - An error from the JDBC driver

Type.resolve(java.lang.Object, org.hibernate.engine.spi.SharedSessionContractImplementor, java.lang.Object)

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 value Hibernate will use in second level caching, so care should be taken to break values down to their simplest forms; for entities especially, this means breaking them down into their constituent parts.

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

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 method is the reciprocal of Type.disassemble(java.lang.Object, org.hibernate.engine.spi.SharedSessionContractImplementor, java.lang.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
