Package org.hibernate.sql.results.graph

Interface Initializer

All Known Subinterfaces:

CollectionInitializer, EmbeddableInitializer, EntityInitializer, FetchParentAccess

All Known Implementing Classes:

AbstractEmbeddableInitializer, AbstractEntityInitializer, AbstractFetchParentAccess

public interface Initializer

Defines a multi-step process for initializing entity, collection and composite state. Each step is performed on each initializer before starting the next step.

Method Summary

Modifier and Type	Method	Description
default void	endLoading(ExecutionContext context)	Lifecycle method called at the very end of the result values processing
void	finishUpRow(RowProcessingState rowProcessingState)	Lifecycle method called at the end of the current row processing.
Object	getInitializedInstance()
ModelPart	getInitializedPart()
NavigablePath	getNavigablePath()
void	initializeInstance(RowProcessingState rowProcessingState)	Step 3 - Initialize the state of the instance resolved in resolveInstance(org.hibernate.sql.results.jdbc.spi.RowProcessingState) from the current row values.
void	resolveInstance(RowProcessingState rowProcessingState)	Step 2 - Using the key resolved in resolveKey(org.hibernate.sql.results.jdbc.spi.RowProcessingState), resolve the instance (of the thing initialized) to use for the current row.
void	resolveKey(RowProcessingState rowProcessingState)	Step 1 - Resolve the key value for this initializer for the current row.

Method Detail

getNavigablePath

NavigablePath getNavigablePath()

getInitializedPart

ModelPart getInitializedPart()

getInitializedInstance

Object getInitializedInstance()

resolveKey

void resolveKey(RowProcessingState rowProcessingState)

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

resolveInstance

void resolveInstance(RowProcessingState rowProcessingState)

Step 2 - Using the key resolved in 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 todo (6.0) : much of the various implementations of this are similar enough to handle in a common base implementation (templating?) things like resolving as managed (Session cache), from second-level cache, from LoadContext, etc..

initializeInstance

void initializeInstance(RowProcessingState rowProcessingState)

Step 3 - Initialize the state of the instance resolved in 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

finishUpRow

void finishUpRow(RowProcessingState rowProcessingState)

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.

endLoading

default void endLoading(ExecutionContext context)

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