EmbeddableInitializerImpl

public EmbeddableInitializerImpl(EmbeddableResultGraphNode resultDescriptor,
 BasicFetch<?> discriminatorFetch,
 InitializerParent<?> parent,
 AssemblerCreationState creationState,
 boolean isResultInitializer)

Method Details

getInitializedPart

public EmbeddableValuedModelPart getInitializedPart()

Specified by:

getInitializedPart in interface EmbeddableInitializer<EmbeddableInitializerImpl.EmbeddableInitializerData>

Specified by:

getInitializedPart in interface Initializer<EmbeddableInitializerImpl.EmbeddableInitializerData>

getParent

public @Nullable InitializerParent<?> getParent()

Description copied from interface: Initializer

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

Specified by:

getParent in interface EmbeddableInitializer<EmbeddableInitializerImpl.EmbeddableInitializerData>

Specified by:

getParent in interface Initializer<EmbeddableInitializerImpl.EmbeddableInitializerData>

getNavigablePath

public NavigablePath getNavigablePath()

Specified by:

getNavigablePath in interface Initializer<EmbeddableInitializerImpl.EmbeddableInitializerData>

isResultInitializer

public boolean isResultInitializer()

Description copied from interface: Initializer

Indicates if this is a result or fetch initializer.

Specified by:

isResultInitializer in interface Initializer<EmbeddableInitializerImpl.EmbeddableInitializerData>

isPartOfKey

public boolean isPartOfKey()

Description copied from interface: Initializer

Indicates whether this initializer is part of a key i.e. entity identifier, foreign key or collection key.

Specified by:

isPartOfKey in interface Initializer<EmbeddableInitializerImpl.EmbeddableInitializerData>

isEager

public boolean isEager()

Description copied from interface: Initializer

Indicates whether calling resolve is needed when the object for this initializer is initialized already.

Specified by:

isEager in interface Initializer<EmbeddableInitializerImpl.EmbeddableInitializerData>

isLazyCapable

public boolean isLazyCapable()

Description copied from interface: Initializer

Indicates whether this initializer or one of its sub-parts could be made lazy.

Specified by:

isLazyCapable in interface Initializer<EmbeddableInitializerImpl.EmbeddableInitializerData>

hasLazySubInitializers

public boolean hasLazySubInitializers()

Description copied from interface: Initializer

Indicates whether this initializer has sub-initializers which are lazy.

Specified by:

hasLazySubInitializers in interface Initializer<EmbeddableInitializerImpl.EmbeddableInitializerData>

createInitializerData

protected InitializerData createInitializerData(RowProcessingState rowProcessingState)

Specified by:

createInitializerData in class AbstractInitializer<EmbeddableInitializerImpl.EmbeddableInitializerData>

resolveKey

public void resolveKey(EmbeddableInitializerImpl.EmbeddableInitializerData 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<EmbeddableInitializerImpl.EmbeddableInitializerData>

Overrides:

resolveKey in class AbstractInitializer<EmbeddableInitializerImpl.EmbeddableInitializerData>

resetResolvedEntityRegistrations

public void resetResolvedEntityRegistrations(RowProcessingState rowProcessingState)

Description copied from interface: EmbeddableInitializer

Resets the resolved entity registrations by i.e. removing EntityHolder. This is used after EntityInitializer.resolveEntityKeyOnly(RowProcessingState) to deregister registrations for entities that were only resolved, but not initialized. Failing to do this will lead to errors, because PersistenceContext.postLoad(JdbcValuesSourceProcessingState, Consumer) is called, which expects all registrations to be fully initialized.

Specified by:

resetResolvedEntityRegistrations in interface EmbeddableInitializer<EmbeddableInitializerImpl.EmbeddableInitializerData>

resolveFromPreviousRow

public void resolveFromPreviousRow(EmbeddableInitializerImpl.EmbeddableInitializerData 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<EmbeddableInitializerImpl.EmbeddableInitializerData>

resolveInstance

public void resolveInstance(EmbeddableInitializerImpl.EmbeddableInitializerData 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<EmbeddableInitializerImpl.EmbeddableInitializerData>

resolveInstance

public void resolveInstance(@Nullable Object instance,
 EmbeddableInitializerImpl.EmbeddableInitializerData 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<EmbeddableInitializerImpl.EmbeddableInitializerData>

initializeInstance

public void initializeInstance(EmbeddableInitializerImpl.EmbeddableInitializerData data)

Description copied from interface: Initializer

Step 3 - Initialize the state of the instance resolved in Initializer.resolveInstance(Data) from the current row values. All resolved state for the current row is injected into the resolved instance

Specified by:

initializeInstance in interface Initializer<EmbeddableInitializerImpl.EmbeddableInitializerData>

Overrides:

initializeInstance in class AbstractInitializer<EmbeddableInitializerImpl.EmbeddableInitializerData>

forEachSubInitializer

protected void forEachSubInitializer(BiConsumer<Initializer<?>,RowProcessingState> consumer,
 InitializerData data)

Specified by:

forEachSubInitializer in class AbstractInitializer<EmbeddableInitializerImpl.EmbeddableInitializerData>

initializeInstanceFromParent

public void initializeInstanceFromParent(Object parentInstance,
 EmbeddableInitializerImpl.EmbeddableInitializerData 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<EmbeddableInitializerImpl.EmbeddableInitializerData>

resolveState

public void resolveState(EmbeddableInitializerImpl.EmbeddableInitializerData data)

Specified by:

resolveState in interface Initializer<EmbeddableInitializerImpl.EmbeddableInitializerData>

toString

public String toString()

Overrides:

toString in class Object
