EntityDelayedFetchInitializer

public EntityDelayedFetchInitializer(FetchParentAccess parentAccess,
                                     NavigablePath fetchedNavigable,
                                     ToOneAttributeMapping referencedModelPart,

Method Detail

getNavigablePath

public NavigablePath getNavigablePath()

Specified by:

getNavigablePath in interface FetchParentAccess

Specified by:

getNavigablePath in interface Initializer

resolveKey

public void resolveKey(RowProcessingState rowProcessingState)

Description copied from interface: Initializer

Step 1 - Resolve the key value for this initializer for the current row. After this point, the initializer knows the entity/collection/component key for the current row

Specified by:

resolveKey in interface Initializer

getInitializedPart

public ModelPart getInitializedPart()

Specified by:

getInitializedPart in interface Initializer

resolveInstance

public void resolveInstance(RowProcessingState rowProcessingState)

Description copied from interface: Initializer

Step 2 - Using the key resolved in Initializer.resolveKey(org.hibernate.sql.results.jdbc.spi.RowProcessingState), 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

Specified by:

resolveInstance in interface Initializer

initializeInstance

public void initializeInstance(RowProcessingState rowProcessingState)

Description copied from interface: Initializer

Step 3 - Initialize the state of the instance resolved in Initializer.resolveInstance(org.hibernate.sql.results.jdbc.spi.RowProcessingState) from the current row values. All resolved state for the current row is injected into the resolved instance

Specified by:

initializeInstance in interface Initializer

finishUpRow

public void finishUpRow(RowProcessingState rowProcessingState)

Description copied from interface: Initializer

Lifecycle method called at the end of the current row processing. Provides ability to complete processing from the current row and prepare for the next row.

Specified by:

finishUpRow in interface Initializer

markShallowCached

public void markShallowCached()

Specified by:

markShallowCached in interface Initializer

endLoading

public void endLoading(ExecutionContext executionContext)

Description copied from interface: Initializer

Lifecycle method called at the very end of the result values processing

Specified by:

endLoading in interface Initializer

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

getEntityInstance

public Object getEntityInstance()

Description copied from interface: EntityInitializer

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

Specified by:

getEntityInstance in interface EntityInitializer

isEntityInitialized

public boolean isEntityInitialized()

Specified by:

isEntityInitialized in interface EntityInitializer

Returns:

true if the current entity associated to this EntityInitializer has been initialized
