Method Details

getCardinality

public EntityCollectionPart.Cardinality getCardinality()

Specified by:

getCardinality in interface EntityCollectionPart

breakDownJdbcValues

public <X,
Y> int breakDownJdbcValues(Object domainValue,
 int offset,
 X x,
 Y y,
 ModelPart.JdbcValueBiConsumer<X,Y> valueConsumer,
 SharedSessionContractImplementor session)

Description copied from interface: ModelPart

Breaks down the domain value to its constituent JDBC values. Think of it as breaking the multi-dimensional array into a visitable flat array. Additionally, it passes through the values X and Y to the consumer. Returns the amount of jdbc types that have been visited.

Specified by:

breakDownJdbcValues in interface ModelPart

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

getSelectable

public SelectableMapping getSelectable(int columnIndex)

Description copied from interface: SelectableMappings

Get the selectable at the given position

Specified by:

getSelectable in interface SelectableMappings

forEachSelectable

public int forEachSelectable(int offset,
 SelectableConsumer consumer)

Description copied from interface: ModelPart

Visits each selectable mapping with the selectable index offset by the given value. Returns the amount of jdbc types that have been visited.

Specified by:

forEachSelectable in interface ModelPart

Specified by:

forEachSelectable in interface SelectableMappings

Specified by:

forEachSelectable in interface ValuedModelPart

• SelectableConsumer.accept(int, SelectableMapping)

resolveFetchAssociationKey

protected AssociationKey resolveFetchAssociationKey()

Specified by:

resolveFetchAssociationKey in class AbstractEntityCollectionPart

hasPartitionedSelectionMapping

public boolean hasPartitionedSelectionMapping()

Specified by:

hasPartitionedSelectionMapping in interface ModelPart

getDefaultSqlAstJoinType

public SqlAstJoinType getDefaultSqlAstJoinType(TableGroup parentTableGroup)

Specified by:

getDefaultSqlAstJoinType in interface TableGroupJoinProducer

isSimpleJoinPredicate

public boolean isSimpleJoinPredicate(Predicate predicate)

Description copied from interface: TableGroupJoinProducer

Returns whether the given predicate is a simple join predicate for this attribute. This is useful to understand if a predicate has additional conjunctions other than the FK related predicate.

Specified by:

isSimpleJoinPredicate in interface TableGroupJoinProducer

createTableGroupJoin

public TableGroupJoin createTableGroupJoin(NavigablePath navigablePath,
 TableGroup lhs,
 @Nullable String explicitSourceAlias,
 @Nullable SqlAliasBase explicitSqlAliasBase,
 @Nullable 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,
 @Nullable String explicitSourceAlias,
 @Nullable SqlAliasBase explicitSqlAliasBase,
 @Nullable SqlAstJoinType sqlAstJoinType,
 boolean fetched,
 @Nullable 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.

createAssociatedTableGroup

public TableGroup createAssociatedTableGroup(boolean canUseInnerJoins,
 NavigablePath append,
 boolean fetched,
 String sourceAlias,
 SqlAliasBase sqlAliasBase,
 SqlAstCreationState creationState)

finishInitialization

public boolean finishInitialization(CollectionPersister collectionDescriptor,
 Collection bootValueMapping,
 String fkTargetModelPartName,
 MappingModelCreationProcess creationProcess)

Description copied from interface: EntityCollectionPart

Perform any delayed initialization.

The initialization is considered successful if the result is true. It is considered unsuccessful if the result is false or an exception is thrown. Unsuccessful initializations are generally retried "later", to allow waiting for model-parts being available e.g.

If the exception is something that will just never succeed, consider throwing an exception with the NonTransientException marker to allow the creation process to stop immediately

Specified by:

finishInitialization in interface EntityCollectionPart

getJdbcMapping

public JdbcMapping getJdbcMapping(int index)

Specified by:

getJdbcMapping in interface JdbcMappingContainer
