public class AggregateEmbeddableInitializerImpl
extends EmbeddableInitializerImpl

An initializer for an embeddable that is mapped as aggregate e.g. STRUCT, JSON or XML. The aggregate selection reads an Object[] from JDBC which serves as data for the nested DomainResultAssembler. This class exposes the Object[] of the aggregate to the nested assemblers through a wrapping RowProcessingState.

Method Details

startLoading

public void startLoading(RowProcessingState rowProcessingState)

Description copied from interface: Initializer

Step 0 - Callback for initializers before the first row is read. It is the responsibility of this initializer to recurse to the sub-initializers and register InitializerData for the initializer id via RowProcessingState.setInitializerData(int, InitializerData). This is useful for e.g. preparing initializers in case of a cache hit.

Specified by:

startLoading in interface Initializer<EmbeddableInitializerImpl.EmbeddableInitializerData>

Overrides:

startLoading in class AbstractInitializer<EmbeddableInitializerImpl.EmbeddableInitializerData>

getAggregateValuesArrayPositions

public int[] getAggregateValuesArrayPositions()

getJdbcValues

public Object[] getJdbcValues(RowProcessingState processingState)
