java.lang.Object

ch.tocco.nice2.persist.core.impl.hibernate.query.selection.AbstractToManySelectionPathHandler

ch.tocco.nice2.persist.core.impl.hibernate.query.selection.binary.AbstractToManyBinaryHandler

All Implemented Interfaces:

SelectionPathHandler

Direct Known Subclasses:

ToManyDetailDocumentHandler, ToManyResourceContentHandler

public abstract class AbstractToManyBinaryHandler
extends AbstractToManySelectionPathHandler

Abstract SelectionPathHandler for all to-many fields of type binary. Only the associated primary key of the entity (Resource_content or the related entity if it's an entity doc) is queried from the database. The BinaryDataAccessor is then used to efficiently query all necessary data based on the retrieved primary keys.

AbstractToManyBinaryHandler

public AbstractToManyBinaryHandler(TypeManager typeManager,
 FieldResolver fieldResolver,
 EntityModel rootModel,
 PredicateFactory predicateFactory,
 List<QueryBuilderInterceptor> interceptors,
 Map<String,ParameterProvider<?>> parameterProviders,
 org.hibernate.Session session,
 jakarta.persistence.criteria.CriteriaBuilder criteriaBuilder)

Method Details

select

public void select(Path path)

Parameters:

path - a path that should be selected by this handler.

processAdditionalQuery

protected void processAdditionalQuery(AbstractToManySelectionPathHandler.QueryHolder queryHolder,
 List<Path> paths)

Specified by:

processAdditionalQuery in class AbstractToManySelectionPathHandler

processResults

public <RT> void processResults(List<Object[]> queryResults,
 List<RT> target,
 SelectionRegistry selectionRegistry,
 ResultRowMapper<RT> mapper)

Description copied from interface: SelectionPathHandler

This is called after the query was executed. The handler is expected to map the query results to the target array that is returned from the query builder.

Parameters:

queryResults - the query result, contains all paths added during SelectionPathHandler.processSelection(SelectionRegistry)

target - the list of arrays that will be returned from the query builder

loadBinaryData

protected abstract Map<Serializable,BinaryData> loadBinaryData(Path path,
 List<Serializable> allKeys)
