Method Detail

createInitializerData

protected InitializerData createInitializerData(RowProcessingState rowProcessingState)

Specified by:

createInitializerData in class AbstractInitializer<Data extends AbstractCollectionInitializer.CollectionInitializerData>

resolveKey

public void resolveKey(Data data)

Description copied from interface: Initializer

Step 1.1 - Resolve the key value for this initializer for the current row and then recurse to the sub-initializers. After this point, the initializer knows whether further processing is necessary for the current row i.e. if the object is missing.

Specified by:

resolveKey in interface Initializer<Data extends AbstractCollectionInitializer.CollectionInitializerData>

Overrides:

resolveKey in class AbstractInitializer<Data extends AbstractCollectionInitializer.CollectionInitializerData>

resolveState

public void resolveState(Data data)

Specified by:

resolveState in interface Initializer<Data extends AbstractCollectionInitializer.CollectionInitializerData>

resolveFromPreviousRow

public void resolveFromPreviousRow(Data data)

Description copied from interface: Initializer

Step 1.2 - Special variant of Initializer.resolveKey(InitializerData) that allows the reuse of key value and instance value from the previous row.

Specified by:

resolveFromPreviousRow in interface Initializer<Data extends AbstractCollectionInitializer.CollectionInitializerData>

setMissing

protected void setMissing(Data data)

resolveCollectionKey

protected void resolveCollectionKey(Data data,
                                    boolean checkPreviousRow)

forEachSubInitializer

protected void forEachSubInitializer(BiConsumer<Initializer<?>,RowProcessingState> consumer,
                                     InitializerData data)

Specified by:

forEachSubInitializer in class AbstractInitializer<Data extends AbstractCollectionInitializer.CollectionInitializerData>

getCollectionInstance

public @Nullable PersistentCollection<?> getCollectionInstance(Data data)

Specified by:

getCollectionInstance in interface CollectionInitializer<Data extends AbstractCollectionInitializer.CollectionInitializerData>

getNavigablePath

public NavigablePath getNavigablePath()

Specified by:

getNavigablePath in interface Initializer<Data extends AbstractCollectionInitializer.CollectionInitializerData>

getCollectionAttributeMapping

public PluralAttributeMapping getCollectionAttributeMapping()

getInitializedPart

public PluralAttributeMapping getInitializedPart()

Specified by:

getInitializedPart in interface CollectionInitializer<Data extends AbstractCollectionInitializer.CollectionInitializerData>

Specified by:

getInitializedPart in interface Initializer<Data extends AbstractCollectionInitializer.CollectionInitializerData>

getParent

public @Nullable InitializerParent<?> getParent()

Description copied from interface: Initializer

Returns the parent Initializer or null if this is a result initializer.

Specified by:

getParent in interface Initializer<Data extends AbstractCollectionInitializer.CollectionInitializerData>

isPartOfKey

public boolean isPartOfKey()

Description copied from interface: Initializer

Indicates whether this initializer is part of a key i.e. entity identifier, foreign key or collection key.

Specified by:

isPartOfKey in interface Initializer<Data extends AbstractCollectionInitializer.CollectionInitializerData>

isEager

public boolean isEager()

Description copied from interface: Initializer

Indicates whether calling resolve is needed when the object for this initializer is initialized already.

Specified by:

isEager in interface Initializer<Data extends AbstractCollectionInitializer.CollectionInitializerData>

hasLazySubInitializers

public boolean hasLazySubInitializers()

Description copied from interface: Initializer

Indicates whether this initializer has sub-initializers which are lazy.

Specified by:

hasLazySubInitializers in interface Initializer<Data extends AbstractCollectionInitializer.CollectionInitializerData>

isResultInitializer

public boolean isResultInitializer()

Description copied from interface: Initializer

Indicates if this is a result or fetch initializer.

Specified by:

isResultInitializer in interface Initializer<Data extends AbstractCollectionInitializer.CollectionInitializerData>
