方法详细资料

getColumnSpan

public int getColumnSpan(Mapping mapping)
                  throws MappingException

从接口复制的说明: Type

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

指定者:

getColumnSpan 在接口中 Type

覆盖:

getColumnSpan 在类中 OneToOneType

参数:

mapping - The mapping object :/

返回:

The number of columns

抛出:

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

sqlTypes

public int[] sqlTypes(Mapping mapping)
               throws MappingException

从接口复制的说明: 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).

指定者:

sqlTypes 在接口中 Type

覆盖:

sqlTypes 在类中 OneToOneType

参数:

mapping - The mapping object :/

返回:

The JDBC type codes.

抛出:

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

dictatedSizes

public Size[] dictatedSizes(Mapping mapping)
                     throws MappingException

从接口复制的说明: 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).

指定者:

dictatedSizes 在接口中 Type

覆盖:

dictatedSizes 在类中 OneToOneType

参数:

mapping - The mapping object :/

返回:

The dictated sizes.

抛出:

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

defaultSizes

public Size[] defaultSizes(Mapping mapping)
                    throws MappingException

从接口复制的说明: 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).

指定者:

defaultSizes 在接口中 Type

覆盖:

defaultSizes 在类中 OneToOneType

参数:

mapping - The mapping object :/

返回:

The default sizes.

抛出:

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

useLHSPrimaryKey

public boolean useLHSPrimaryKey()

从接口复制的说明: AssociationType

Is the primary key of the owning entity table to be used in the join?

指定者:

useLHSPrimaryKey 在接口中 AssociationType

覆盖:

useLHSPrimaryKey 在类中 OneToOneType

hydrate

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

从接口复制的说明: 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

指定者:

hydrate 在接口中 Type

覆盖:

hydrate 在类中 OneToOneType

参数:

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

返回:

An entity or collection key, or an actual value.

抛出:

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

从接口复制的说明: 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.

指定者:

disassemble 在接口中 Type

覆盖:

disassemble 在类中 OneToOneType

参数:

value - the value to cache

session - the originating session

owner - optional parent entity object (needed for collections)

返回:

the disassembled, deep cloned state

抛出:

HibernateException - An error from Hibernate

assemble

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

从接口复制的说明: 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)

指定者:

assemble 在接口中 Type

覆盖:

assemble 在类中 OneToOneType

参数:

oid - the disassembled state from the cache

session - the originating session

owner - the parent entity object

返回:
