 @Nullable Fetch discriminatorFetch,
 @Nullable DomainResult<?> keyResult,
 @Nullable DomainResult<Object> rowIdResult,

Method Details

createInitializerData

protected EntityInitializerImpl.EntityInitializerData createInitializerData(RowProcessingState rowProcessingState)

Specified by:

createInitializerData in class AbstractInitializer<EntityInitializerImpl.EntityInitializerData>

resolveKey

public void resolveKey(EntityInitializerImpl.EntityInitializerData data)

Description copied from interface: Initializer

Step 1.1 - Resolve the key value for this initializer for the current row and then recurse to the sub-initializers.

After this point, the initializer knows whether further processing is necessary for the current row i.e. if the object is missing.

Specified by:

resolveKey in interface Initializer<EntityInitializerImpl.EntityInitializerData>

Overrides:

resolveKey in class AbstractInitializer<EntityInitializerImpl.EntityInitializerData>

getEntityIdentifier

public @Nullable Object getEntityIdentifier(EntityInitializerImpl.EntityInitializerData data)

Specified by:

getEntityIdentifier in interface EntityInitializer<EntityInitializerImpl.EntityInitializerData>

resolveEntityKeyOnly

public @Nullable EntityKey resolveEntityKeyOnly(RowProcessingState rowProcessingState)

Specified by:

resolveEntityKeyOnly in interface EntityInitializer<EntityInitializerImpl.EntityInitializerData>

resetResolvedEntityRegistrations

public void resetResolvedEntityRegistrations(RowProcessingState rowProcessingState)

Description copied from interface: EntityInitializer

Resets the resolved entity registrations by i.e. removing EntityHolder.

Specified by:

resetResolvedEntityRegistrations in interface EntityInitializer<EntityInitializerImpl.EntityInitializerData>

See Also:

• EmbeddableInitializer.resetResolvedEntityRegistrations(RowProcessingState)

resolveKey

protected void resolveKey(EntityInitializerImpl.EntityInitializerData data,
 boolean entityKeyOnly)

resolveInstanceSubInitializers

protected void resolveInstanceSubInitializers(EntityInitializerImpl.EntityInitializerData data)

resolveKeySubInitializers

protected void resolveKeySubInitializers(EntityInitializerImpl.EntityInitializerData data)

resolveEntityKey

@EnsuresNonNull("data.entityKey")
protected void resolveEntityKey(EntityInitializerImpl.EntityInitializerData data,
 Object id)

setMissing

protected void setMissing(EntityInitializerImpl.EntityInitializerData data)

resolveFromPreviousRow

public void resolveFromPreviousRow(EntityInitializerImpl.EntityInitializerData data)

Description copied from interface: Initializer

Step 1.2 - Special variant of Initializer.resolveKey(InitializerData) that allows the reuse of key value and instance value from the previous row.

Specified by:

resolveFromPreviousRow in interface Initializer<EntityInitializerImpl.EntityInitializerData>

initializeInstanceFromParent

public void initializeInstanceFromParent(Object parentInstance,
 EntityInitializerImpl.EntityInitializerData data)

Description copied from interface: Initializer

Step 3.1 - Initialize the state of the instance as extracted from the given parentInstance. Extraction can be done with the Initializer.getInitializedPart(). Initializers are supposed to recursively call this method for sub-initializers.

This alternative initialization protocol is used for shallow query cache hits, in which case there is no data available in the JdbcValuesCacheHit to initialize potentially lazy associations.

Specified by:

initializeInstanceFromParent in interface Initializer<EntityInitializerImpl.EntityInitializerData>

isResultInitializer

public boolean isResultInitializer()

Description copied from interface: Initializer

Indicates if this is a result or fetch initializer.

Specified by:

public ModelPart getInitializedPart()

Specified by:

getInitializedPart in interface Initializer<EntityInitializerImpl.EntityInitializerData>

public NavigablePath getNavigablePath()

Specified by:

getNavigablePath in interface Initializer<EntityInitializerImpl.EntityInitializerData>

Description copied from interface: EntityInitializer

Get the descriptor for the type of entity being initialized

Specified by:

getTargetInstance

public Object getTargetInstance(EntityInitializerImpl.EntityInitializerData data)

Description copied from interface: EntityInitializer

Get the target entity instance for the currently processing "row".

Specified by:

getParent

public @Nullable InitializerParent<?> getParent()

Description copied from interface: Initializer

Returns the parent Initializer or null if this is a result initializer.

Specified by:

 @Nullable BasicResultAssembler<?> discriminatorAssembler,
 EntityPersister entityDescriptor)
                                                                   throws WrongClassException

Throws:

WrongClassException

useEmbeddedIdentifierInstanceAsEntity

protected boolean useEmbeddedIdentifierInstanceAsEntity(EntityInitializerImpl.EntityInitializerData data)

resolveInstance

public void resolveInstance(Object instance,
 EntityInitializerImpl.EntityInitializerData data)

Description copied from interface: Initializer

Step 2.2 - Use the given instance as resolved instance for this initializer. Initializers are supposed to recursively call this method for sub-initializers.

This alternative initialization protocol is used when a parent instance was already part of the persistence context.

Specified by:

resolveInstance in interface Initializer<EntityInitializerImpl.EntityInitializerData>

resolveInstance

public void resolveInstance(EntityInitializerImpl.EntityInitializerData data)

Description copied from interface: Initializer

Step 2.1 - Using the key resolved in Initializer.resolveKey(Data), resolve the instance (of the thing initialized) to use for the current row.

After this point, the initializer knows the entity/collection/component instance for the current row based on the resolved key. If the resolving was successful, Initializer.getResolvedInstance(RowProcessingState) will return that instance.

Specified by:

resolveInstance in interface Initializer<EntityInitializerImpl.EntityInitializerData>
