Method Details

resolveInstance

public void resolveInstance(AbstractCollectionInitializer.CollectionInitializerData data)

Description copied from interface: Initializer

Step 2.1 - Using the key resolved in Initializer.resolveKey(Data), 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. If the resolving was successful, Initializer.getResolvedInstance(RowProcessingState) will return that instance.

resolveInstance

public void resolveInstance(@Nullable Object instance,
 AbstractCollectionInitializer.CollectionInitializerData data)

Description copied from interface: Initializer

Step 2.2 - Use the given instance as resolved instance for this initializer. Initializers are supposed to recursively call this method for sub-initializers.

This alternative initialization protocol is used when a parent instance was already part of the persistence context.

initializeInstanceFromParent

public void initializeInstanceFromParent(Object parentInstance,
 AbstractCollectionInitializer.CollectionInitializerData data)

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.

toString
