Constructor Details

EntityDelayedFetchInitializer

public EntityDelayedFetchInitializer(InitializerParent<?> parent,
 NavigablePath fetchedNavigable,
 ToOneAttributeMapping referencedModelPart,
 boolean selectByUniqueKey,
 DomainResult<?> keyResult,
 @Nullable BasicFetch<?> discriminatorResult,
 AssemblerCreationState creationState)

Method Details

createInitializerData

protected InitializerData createInitializerData(RowProcessingState rowProcessingState)

Specified by:

createInitializerData in class AbstractInitializer<EntityDelayedFetchInitializer.EntityDelayedFetchInitializerData>

getNavigablePath

public NavigablePath getNavigablePath()

Specified by:

getNavigablePath in interface Initializer<EntityDelayedFetchInitializer.EntityDelayedFetchInitializerData>

getInitializedPart

public ModelPart getInitializedPart()

Specified by:

getInitializedPart in interface Initializer<EntityDelayedFetchInitializer.EntityDelayedFetchInitializerData>

resolveFromPreviousRow

public void resolveFromPreviousRow(EntityDelayedFetchInitializer.EntityDelayedFetchInitializerData 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<EntityDelayedFetchInitializer.EntityDelayedFetchInitializerData>

resolveInstance

public void resolveInstance(EntityDelayedFetchInitializer.EntityDelayedFetchInitializerData 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<EntityDelayedFetchInitializer.EntityDelayedFetchInitializerData>

resolveInstance

public void resolveInstance(Object instance,
 EntityDelayedFetchInitializer.EntityDelayedFetchInitializerData 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<EntityDelayedFetchInitializer.EntityDelayedFetchInitializerData>

forEachSubInitializer

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

Specified by:

forEachSubInitializer in class AbstractInitializer<EntityDelayedFetchInitializer.EntityDelayedFetchInitializerData>

getEntityDescriptor

public EntityPersister getEntityDescriptor()

Description copied from interface: EntityInitializer

Get the descriptor for the type of entity being initialized

Specified by:

getEntityDescriptor in interface EntityInitializer<EntityDelayedFetchInitializer.EntityDelayedFetchInitializerData>

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 Initializer<EntityDelayedFetchInitializer.EntityDelayedFetchInitializerData>

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<EntityDelayedFetchInitializer.EntityDelayedFetchInitializerData>

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<EntityDelayedFetchInitializer.EntityDelayedFetchInitializerData>

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<EntityDelayedFetchInitializer.EntityDelayedFetchInitializerData>

isResultInitializer

public boolean isResultInitializer()

Description copied from interface: Initializer

Indicates if this is a result or fetch initializer.

Specified by:

isResultInitializer in interface Initializer<EntityDelayedFetchInitializer.EntityDelayedFetchInitializerData>

getConcreteDescriptor

public EntityPersister getConcreteDescriptor(EntityDelayedFetchInitializer.EntityDelayedFetchInitializerData data)

Specified by:

getConcreteDescriptor in interface EntityInitializer<EntityDelayedFetchInitializer.EntityDelayedFetchInitializerData>

resolveState

public void resolveState(EntityDelayedFetchInitializer.EntityDelayedFetchInitializerData data)

Specified by:

resolveState in interface Initializer<EntityDelayedFetchInitializer.EntityDelayedFetchInitializerData>

getEntityIdentifier

public @Nullable Object getEntityIdentifier(EntityDelayedFetchInitializer.EntityDelayedFetchInitializerData data)

Specified by:

getEntityIdentifier in interface EntityInitializer<EntityDelayedFetchInitializer.EntityDelayedFetchInitializerData>

toString

public String toString()

Overrides:

toString in class Object

isSelectByUniqueKey

protected boolean isSelectByUniqueKey()

getIdentifierAssembler

protected DomainResultAssembler<?> getIdentifierAssembler()

getDiscriminatorAssembler

protected @Nullable BasicResultAssembler<?> getDiscriminatorAssembler()
