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(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.

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<AbstractCollectionInitializer.CollectionInitializerData>

Overrides:

isEager in class AbstractCollectionInitializer<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<AbstractCollectionInitializer.CollectionInitializerData>

Overrides:

hasLazySubInitializers in class AbstractCollectionInitializer<AbstractCollectionInitializer.CollectionInitializerData>

toString

public String toString()

Overrides:

toString in class Object
