Class AbstractToOneBinaryHandler

java.lang.Object

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

All Implemented Interfaces:

SelectionPathHandler

Direct Known Subclasses:

ToOneDetailDocumentHandler, ToOneResourceContentHandler

public abstract class AbstractToOneBinaryHandler
extends Object
implements SelectionPathHandler

Abstract SelectionPathHandler for all to-one 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.

Method Details

select

public void select(Path path)

Specified by:

select in interface SelectionPathHandler

Parameters:

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

processSelection

public void processSelection(SelectionRegistry selectionRegistry)

Description copied from interface: SelectionPathHandler

This is called before the query is executed. The handler can add all required selection paths to the given SelectionRegistry.

Specified by:

processSelection in interface SelectionPathHandler

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.

Specified by:

processResults in interface SelectionPathHandler

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> keys)
