AbstractEmbeddableInitializer

                                     FetchParentAccess fetchParentAccess,
                                     AssemblerCreationState creationState)

Method Detail

initializeAssemblers

                                    AssemblerCreationState creationState,

getInitializedPart

public EmbeddableValuedModelPart getInitializedPart()

Specified by:

getInitializedPart in interface EmbeddableInitializer

Specified by:

getInitializedPart in interface Initializer

getFetchParentAccess

public FetchParentAccess getFetchParentAccess()

Specified by:

getFetchParentAccess in interface EmbeddableInitializer

getNavigablePath

public NavigablePath getNavigablePath()

Specified by:

getNavigablePath in interface FetchParentAccess

Specified by:

getNavigablePath in interface Initializer

getCompositeInstance

public Object getCompositeInstance()

Specified by:

getCompositeInstance in interface EmbeddableInitializer

findFirstEntityDescriptorAccess

public FetchParentAccess findFirstEntityDescriptorAccess()

Description copied from interface: FetchParentAccess

Find the first entity access up the fetch parent graph

Specified by:

findFirstEntityDescriptorAccess in interface FetchParentAccess

findFirstEntityInitializer

public EntityInitializer findFirstEntityInitializer()

Specified by:

findFirstEntityInitializer in interface FetchParentAccess

resolveKey

public void resolveKey(RowProcessingState processingState)

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

resolveInstance

public void resolveInstance(RowProcessingState processingState)

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

initializeInstance

public void initializeInstance(RowProcessingState processingState)

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

getValues

public Object[] getValues()

Description copied from interface: ValueAccess

The complete set of values.

Specified by:

getValues in interface ValueAccess

getValue

public <T> T getValue(int i,
                      Class<T> clazz)

Description copied from interface: ValueAccess

Access to an individual value.

Specified by:

getValue in interface ValueAccess

getOwner

public Object getOwner()

Description copied from interface: ValueAccess

Access to the owner of the instance being instantiated

Specified by:

getOwner in interface ValueAccess

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

toString

public String toString()

Overrides:
