 DomainResult<?> keyResult,
 boolean affectedByFilter,

Method Details

registerResolutionListener

protected abstract void registerResolutionListener(Data data)

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 AbstractBatchEntitySelectFetchInitializer.AbstractBatchEntitySelectFetchInitializerData>

Overrides:

resolveKey in class AbstractInitializer<Data extends AbstractBatchEntitySelectFetchInitializer.AbstractBatchEntitySelectFetchInitializerData>

resolveInstance

public void resolveInstance(Data 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.

Specified by:

resolveInstance in interface Initializer<Data extends AbstractBatchEntitySelectFetchInitializer.AbstractBatchEntitySelectFetchInitializerData>

Overrides:

resolveInstance in class EntitySelectFetchInitializer<Data extends AbstractBatchEntitySelectFetchInitializer.AbstractBatchEntitySelectFetchInitializerData>

resolveInstanceFromIdentifier

protected void resolveInstanceFromIdentifier(Data data)

resolveInstance

public void resolveInstance(Object instance,
 Data 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.

Specified by:

resolveInstance in interface Initializer<Data extends AbstractBatchEntitySelectFetchInitializer.AbstractBatchEntitySelectFetchInitializerData>

Overrides:

resolveInstance in class EntitySelectFetchInitializer<Data extends AbstractBatchEntitySelectFetchInitializer.AbstractBatchEntitySelectFetchInitializerData>

initializeInstance

public void initializeInstance(Data data)

Description copied from interface: Initializer

Step 3 - Initialize the state of the instance resolved in Initializer.resolveInstance(Data) from the current row values.

All resolved state for the current row is injected into the resolved instance

Specified by:

initializeInstance in interface Initializer<Data extends AbstractBatchEntitySelectFetchInitializer.AbstractBatchEntitySelectFetchInitializerData>

Overrides:

initializeInstance in class EntitySelectFetchInitializer<Data extends AbstractBatchEntitySelectFetchInitializer.AbstractBatchEntitySelectFetchInitializerData>

getExistingInitializedInstance

protected Object getExistingInitializedInstance(Data data)

registerToBatchFetchQueue

protected void registerToBatchFetchQueue(Data data)

initializeInstanceFromParent

public void initializeInstanceFromParent(Object parentInstance,
 Data 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.

Specified by:

initializeInstanceFromParent in interface Initializer<Data extends AbstractBatchEntitySelectFetchInitializer.AbstractBatchEntitySelectFetchInitializerData>

Overrides:

initializeInstanceFromParent in class EntitySelectFetchInitializer<Data extends AbstractBatchEntitySelectFetchInitializer.AbstractBatchEntitySelectFetchInitializerData>

loadInstance

protected static Object loadInstance(EntityKey entityKey,
 ToOneAttributeMapping toOneMapping,
 boolean affectedByFilter,

getParentEntityAttributes

protected AttributeMapping[] getParentEntityAttributes(String attributeName)

getParentEntityAttribute

protected static AttributeMapping getParentEntityAttribute(EntityMappingType subMappingType,
 ToOneAttributeMapping referencedModelPart,
 String attributeName)
