方法详细资料

hasSubclasses

boolean hasSubclasses()

Does this persistent class have subclasses?

getDiscriminatorType

Type getDiscriminatorType()

Get the discriminator type

getDiscriminatorValue

Object getDiscriminatorValue()

Get the discriminator value

getSubclassForDiscriminatorValue

String getSubclassForDiscriminatorValue(Object value)

Get the concrete subclass corresponding to the given discriminator value

getIdentifierColumnNames

String[] getIdentifierColumnNames()

Get the names of columns used to persist the identifier

getIdentifierAliases

String[] getIdentifierAliases(String suffix)

Get the result set aliases used for the identifier columns, given a suffix

getPropertyAliases

String[] getPropertyAliases(String suffix,
                            int i)

Get the result set aliases used for the property columns, given a suffix (properties of this class, only).

getPropertyColumnNames

String[] getPropertyColumnNames(int i)

Get the result set column names mapped for this property (properties of this class, only).

getDiscriminatorAlias

String getDiscriminatorAlias(String suffix)

Get the result set aliases used for the identifier columns, given a suffix

getDiscriminatorColumnName

String getDiscriminatorColumnName()

返回:

the column name for the discriminator as specified in the mapping.

hasRowId

boolean hasRowId()

Does the result set contain rowids?

hydrate

Object[] hydrate(ResultSet rs,
                 Serializable id,
                 Object object,
                 Loadable rootLoadable,
                 String[][] suffixedPropertyColumns,
                 boolean allProperties,
                 SharedSessionContractImplementor session)
          throws SQLException,
                 HibernateException

Retrieve property values from one row of a result set

抛出:

SQLException

HibernateException

isAbstract

boolean isAbstract()

registerAffectingFetchProfile

void registerAffectingFetchProfile(String fetchProfileName)

Register the name of a fetch profile determined to have an affect on the underlying loadable in regards to the fact that the underlying load SQL needs to be adjust when the given fetch profile is enabled.

参数:

fetchProfileName - The name of the profile affecting this.

getTableAliasForColumn

String getTableAliasForColumn(String columnName,
                              String rootAlias)

Given a column name and the root table alias in use for the entity hierarchy, determine the proper table alias for the table in that hierarchy that contains said column.

NOTE : Generally speaking the column is not validated to exist. Most implementations simply return the root alias; the exception is JoinedSubclassEntityPersister

参数:

columnName - The column name

rootAlias - The hierarchy root alias

返回:

The proper table alias for qualifying the given column.
