public interface Value
extends Serializable

A mapping model object which represents something that's persisted "by value", instead of "by reference", that is, anything with no primary key.

A Value is essentially a Hibernate Type, together with zero or more columns. In the mapping model, a Value always comes wrapped in something with higher-level semantics, for example, a property, a collection, or a class.

Method Detail

getColumnSpan

int getColumnSpan()

The number of columns and formulas in the mapping.

getSelectables

List<Selectable> getSelectables()

The mapping to columns and formulas.

getColumns

List<Column> getColumns()

If the mapping involves only columns, return them.

Throws:

AssertionFailure - if the mapping involves formulas

getVirtualSelectables

default List<Selectable> getVirtualSelectables()

Same as getSelectables() except it returns the PK for the non-owning side of a one-to-one association.

getConstraintColumns

default List<Column> getConstraintColumns()

Same as getColumns() except it returns the PK for the non-owning side of a one-to-one association.

Throws:

AssertionFailure - if the mapping involves formulas

getType

Type getType()
      throws MappingException

Throws:

MappingException

getSelectableType

@Incubating
default JdbcMapping getSelectableType(Mapping factory,
                                      int index)
                               throws MappingException

Throws:

MappingException

getFetchMode

FetchMode getFetchMode()

getTable

Table getTable()

hasFormula

boolean hasFormula()

isAlternateUniqueKey

boolean isAlternateUniqueKey()

isNullable

boolean isNullable()

createForeignKey

void createForeignKey()

createUniqueKey

void createUniqueKey()

isSimpleValue

boolean isSimpleValue()

isValid

boolean isValid(Mapping mapping)
         throws MappingException

Throws:

MappingException

setTypeUsingReflection

void setTypeUsingReflection(String className,
                            String propertyName)
                     throws MappingException

Throws:

MappingException

accept

Object accept(ValueVisitor visitor)

isSame

boolean isSame(Value other)

getColumnInsertability

boolean[] getColumnInsertability()

hasAnyInsertableColumns

boolean hasAnyInsertableColumns()

getColumnUpdateability

boolean[] getColumnUpdateability()

hasAnyUpdatableColumns

boolean hasAnyUpdatableColumns()

getBuildingContext

@Incubating
default MetadataBuildingContext getBuildingContext()

getServiceRegistry

ServiceRegistry getServiceRegistry()

copy

Value copy()

isColumnInsertable

boolean isColumnInsertable(int index)

isColumnUpdateable

boolean isColumnUpdateable(int index)

getExtraCreateTableInfo

@Incubating
default String getExtraCreateTableInfo()

checkColumnDuplication

@Internal
default void checkColumnDuplication(Set<String> distinctColumns,
                                    String owner)

Checks if this value contains any duplicate column. A column is considered duplicate when its name is already contained in the distinctColumn set.

If a duplicate column is found, a MappingException is thrown.

Parameters:

distinctColumns - set containing the names of the columns to check

owner - the owner of this value, used just for error reporting
