All Implemented Interfaces:

MiddleComponentMapper

public class MiddleMapKeyPropertyComponentMapper
extends AbstractMiddleComponentMapper

A component mapper for the @MapKey mapping with the name parameter specified: the value of the map's key is a property of the entity. This doesn't have an effect on the data stored in the versions tables, so mapToMapFromObject is empty.

Method Summary

Modifier and Type	Method	Description
void	addMiddleEqualToQuery(Parameters parameters, String idPrefix1, String prefix1, String idPrefix2, String prefix2)	Adds query statements, which contains restrictions, which express the property that part of the middle entity with alias prefix1, is equal to part of the middle entity with alias prefix2 (the entity is the same).
void	mapToMapFromObject(SessionImplementor session, Map<String,Object> idData, Map<String,Object> data, Object obj)	Maps from an object to the object's map representation (for an entity - only its id).
Object	mapToObjectFromFullMap(EntityInstantiator entityInstantiator, Map<String,Object> data, Object dataObject, Number revision)	Maps from full object data, contained in the given map (or object representation of the map, if available), to an object.

Method Detail

mapToObjectFromFullMap

public Object mapToObjectFromFullMap(EntityInstantiator entityInstantiator,
                                     Map<String,Object> data,
                                     Object dataObject,
                                     Number revision)

Description copied from interface: MiddleComponentMapper

Maps from full object data, contained in the given map (or object representation of the map, if available), to an object.

Parameters:

entityInstantiator - An entity instatiator bound with an open versions reader.

data - Full object data.

dataObject - An optional object representation of the data.

revision - Revision at which the data is read.

Returns:

An object with data corresponding to the one found in the given map.

mapToMapFromObject

public void mapToMapFromObject(SessionImplementor session,
                               Map<String,Object> idData,
                               Map<String,Object> data,
                               Object obj)

Description copied from interface: MiddleComponentMapper

Maps from an object to the object's map representation (for an entity - only its id).

Parameters:

session - The current session.

idData - Map to which composite-id data should be added.

data - Map to which data should be added.

obj - Object to map from.

addMiddleEqualToQuery

public void addMiddleEqualToQuery(Parameters parameters,
                                  String idPrefix1,
                                  String prefix1,
                                  String idPrefix2,
                                  String prefix2)

Description copied from interface: MiddleComponentMapper

Adds query statements, which contains restrictions, which express the property that part of the middle entity with alias prefix1, is equal to part of the middle entity with alias prefix2 (the entity is the same). The part is the component's representation in the middle entity.

Parameters:

parameters - Parameters, to which to add the statements.

idPrefix1 - First alias of the entity + prefix + id to add to the properties.

prefix1 - First alias of the entity + prefix to add to the properties.

idPrefix2 - Second alias of the entity + prefix + id to add to the properties.

prefix2 - Second alias of the entity + prefix to add to the properties.
