Interface EntityDiscriminatorMapping

All Superinterfaces:

BasicValuedMapping, BasicValuedModelPart, Bindable, DiscriminatorMapping, Fetchable, FetchOptions, FetchStyleAccess, FetchTimingAccess, JavaTypedExpressible, JdbcMappingContainer, MappingModelExpressible, ModelPart, SelectableMapping, SelectableMappings, SqlExpressible, SqlTypedMapping, ValuedModelPart, ValueMapping, VirtualModelPart

All Known Implementing Classes:

AbstractDiscriminatorMapping, CaseStatementDiscriminatorMappingImpl, ExplicitColumnDiscriminatorMappingImpl

public interface EntityDiscriminatorMapping
extends DiscriminatorMapping, FetchOptions

Details about the discriminator for an entity hierarchy.

• DiscriminatorColumn
• DiscriminatorValue

Implementation Note:

All entity-mappings within the hierarchy share the same EntityDiscriminatorMapping instance.

Method Details

matchesRoleName

static boolean matchesRoleName(String name)

getPartName

default String getPartName()

Description copied from interface: ModelPart

The local part name, which is generally the unqualified role name

Specified by:

getPartName in interface ModelPart

getFetchableName

default String getFetchableName()

Description copied from interface: Fetchable

The name of the fetchable. This is the part's "local name".

Specified by:

getFetchableName in interface Fetchable

See Also:

• ModelPart.getNavigableRole()
• NavigableRole.getLocalName()

hasPhysicalColumn

boolean hasPhysicalColumn()

Is the discriminator defined by a physical column?

getFetchableKey

default int getFetchableKey()

Description copied from interface: Fetchable

The key that identifies this Fetchable within a FetchableContainer. If this Fetchable is part of FetchableContainer.visitFetchables(IndexedConsumer, EntityMappingType), the values is guaranteed to be between 0 (inclusive) and FetchableContainer.getNumberOfFetchableKeys() (exclusive). Other Fetchable objects may have a special negative value.

The main intent of this key is to index e.g. Fetch objects in an array.

Specified by:

getFetchableKey in interface Fetchable

getMappedFetchOptions

default FetchOptions getMappedFetchOptions()

Description copied from interface: Fetchable

The configured fetch timing and style

Specified by:

getMappedFetchOptions in interface Fetchable

getStyle

default FetchStyle getStyle()

Specified by:

getStyle in interface FetchStyleAccess

getTiming

default FetchTiming getTiming()

Specified by:

getTiming in interface FetchTimingAccess
