Method Details

hasContainingClass

public boolean hasContainingClass()

Description copied from interface: CompositeIdentifierMapping

Does the identifier have a corresponding EmbeddableId or IdClass?

Specified by:

hasContainingClass in interface CompositeIdentifierMapping

Returns:

false if there is not an IdCass or an EmbeddableId

getMappedType

public EmbeddableMappingType getMappedType()

Description copied from interface: ValueMapping

Descriptor for the type of this mapping

Specified by:

getMappedType in interface EmbeddableValuedModelPart

Specified by:

getMappedType in interface ValueMapping

getEmbeddableTypeDescriptor

public EmbeddableMappingType getEmbeddableTypeDescriptor()

Specified by:

getEmbeddableTypeDescriptor in interface EmbeddableValuedModelPart

getContainingTableExpression

public String getContainingTableExpression()

Description copied from interface: ValuedModelPart

The table which contains the columns mapped by this value

Specified by:

getContainingTableExpression in interface ValuedModelPart

getNavigableRole

public NavigableRole getNavigableRole()

Specified by:

getNavigableRole in interface ModelPart

See Also:

• ModelPart.getPartName()

generateFetch

public Fetch generateFetch(FetchParent fetchParent,
 NavigablePath fetchablePath,
 FetchTiming fetchTiming,
 boolean selected,
 String resultVariable,
 DomainResultCreationState creationState)

Description copied from interface: Fetchable

Generates a Fetch of this fetchable

Specified by:

generateFetch in interface Fetchable

Parameters:

fetchParent - The parent of the Fetch we are generating

fetchablePath - The overall path within the graph

fetchTiming - The requested fetch timing

createTableGroupJoin

public TableGroupJoin createTableGroupJoin(NavigablePath navigablePath,
 TableGroup lhs,
 String explicitSourceAlias,
 SqlAliasBase explicitSqlAliasBase,
 SqlAstJoinType requestedJoinType,
 boolean fetched,
 boolean addsPredicate,
 SqlAstCreationState creationState)

Description copied from interface: TableGroupJoinProducer

Create a TableGroupJoin.

Specified by:

createTableGroupJoin in interface TableGroupJoinProducer

Parameters:

navigablePath - The NavigablePath to the join

lhs - The join's (L)eft-(H)and (S)ide

explicitSqlAliasBase - A specific SqlAliasBase to use. May be null indicating one should be created using the SqlAliasBaseGenerator from creationState

requestedJoinType - An explicit join-type. May be null to signal that the join is for an implicit path.

addsPredicate - Indicates there are explicit, additional predicates (from an SQM tree ON/WITH clause)

createRootTableGroupJoin

public TableGroup createRootTableGroupJoin(NavigablePath navigablePath,
 TableGroup lhs,
 String explicitSourceAlias,
 SqlAliasBase explicitSqlAliasBase,
 SqlAstJoinType sqlAstJoinType,
 boolean fetched,
 Consumer<Predicate> predicateConsumer,
 SqlAstCreationState creationState)

Description copied from interface: TableGroupJoinProducer

Create the "join", but return a TableGroup. Intended for creating sub-query correlations. E.g., given

     from SomeEntity e
     where exists (
         select 1
         from AnotherEntity a
         where e.association.attr = 1
     )
 

We call this for the `e.association` path.

Specified by:

createRootTableGroupJoin in interface TableGroupJoinProducer

Parameters:

navigablePath - The NavigablePath to the join

lhs - The join's (L)eft-(H)and (S)ide

explicitSqlAliasBase - A specific SqlAliasBase to use. May be null indicating one should be created using the SqlAliasBaseGenerator from creationState

sqlAstJoinType - An explicit join-type. May be null to signal that the join is for an implicit path.

predicateConsumer - Consumer for additional predicates from the producer's mapping.
