Method Detail

getInitializedPart

public ModelPart getInitializedPart()

public NavigablePath getNavigablePath()

Specified by:

getIdentifierAssembler

protected DomainResultAssembler<?> getIdentifierAssembler()

isMissing

protected boolean isMissing()

setMissing

protected void setMissing(boolean missing)

isEntityReturn

protected abstract boolean isEntityReturn()

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

getKeyValue

public Object getKeyValue()

getEntityKey

public EntityKey getEntityKey()

Specified by:

getEntityKey in interface EntityInitializer

getParentKey

public Object getParentKey()

Specified by:

getParentKey in interface FetchParentAccess

registerResolutionListener

public void registerResolutionListener(Consumer<Object> listener)

Description copied from interface: FetchParentAccess

Register a listener to be notified when the parent is "resolved"

Specified by:

registerResolutionListener in interface FetchParentAccess

Overrides:

registerResolutionListener in class AbstractFetchParentAccess

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

resolveEntityKey

protected void resolveEntityKey(RowProcessingState rowProcessingState)

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 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..

Specified by:

resolveInstance in interface Initializer
