Method Detail

getInitializedPart

public ModelPart getInitializedPart()

Specified by:

getInitializedPart in interface Initializer

getNavigablePath

public NavigablePath getNavigablePath()

Specified by:

getNavigablePath in interface FetchParentAccess

Specified by:

getNavigablePath in interface Initializer

isPartOfKey

public boolean isPartOfKey()

Specified by:

isPartOfKey in interface Initializer

isResultInitializer

public boolean isResultInitializer()

Specified by:

isResultInitializer 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

registerResolutionListener

protected abstract void registerResolutionListener()

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

getExistingInitializedInstance

protected Object getExistingInitializedInstance(RowProcessingState rowProcessingState)

registerToBatchFetchQueue

protected void registerToBatchFetchQueue(RowProcessingState rowProcessingState)

initializeInstanceFromParent

public void initializeInstanceFromParent(Object parentInstance,
                                         RowProcessingState rowProcessingState)

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

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

Description copied from interface: EntityInitializer

Get the descriptor for the type of entity being initialized

Specified by:

getEntityDescriptor in interface EntityInitializer

getEntityInstance
