          extended by org.eclipse.persistence.mappings.CollectionMapping
              extended by org.eclipse.persistence.mappings.AggregateCollectionMapping
All Implemented Interfaces:
java.io.Serializable, java.lang.Cloneable, ContainerMapping, EmbeddableMapping, MapComponentMapping, RelationalMapping

public class AggregateCollectionMapping
extends CollectionMapping
implements RelationalMapping, MapComponentMapping, EmbeddableMapping

Purpose: The aggregate collection mapping is used to represent the aggregate relationship between a single source object and a collection of target objects. The target objects cannot exist without the existence of the source object (privately owned) Unlike the normal aggregate mapping, there is a target table being mapped from the target objects. Unlike normal 1:m mapping, there is no 1:1 back reference mapping, as foreign key constraints have been resolved by the aggregation.

Field Detail

targetForeignKeyFields

protected transient java.util.Vector<org.eclipse.persistence.internal.helper.DatabaseField> targetForeignKeyFields
This is a key in the target table which is a foreign key in the target table.


sourceKeyFields

protected transient java.util.Vector<org.eclipse.persistence.internal.helper.DatabaseField> sourceKeyFields
This is a primary key in the source table that is used as foreign key in the target table


targetForeignKeyToSourceKeys

protected transient java.util.Map<org.eclipse.persistence.internal.helper.DatabaseField,org.eclipse.persistence.internal.helper.DatabaseField> targetForeignKeyToSourceKeys
Foreign keys in the target table to the related keys in the source table


aggregateToSourceFieldNames

protected transient java.util.Map<java.lang.String,java.lang.String> aggregateToSourceFieldNames
Map the name of a field in the aggregate collection descriptor to a field in the actual table specified in the mapping.


nestedAggregateToSourceFieldNames

protected transient java.util.Map<java.lang.String,java.util.Map<java.lang.String,java.lang.String>> nestedAggregateToSourceFieldNames
Map the name of an attribute of the reference descriptor mapped with AggregateCollectionMapping to aggregateToSourceFieldNames that should be applied to this mapping.


remoteReferenceDescriptor

protected ClassDescriptor remoteReferenceDescriptor
In RemoteSession case the mapping needs the reference descriptor serialized from the server, but referenceDescriptor attribute defined as transient in the superclass. To overcome that in non-remote case referenceDescriptor is assigned to remoteReferenceDescriptor; in remote - another way around.


isEntireObjectPK

protected transient boolean isEntireObjectPK
Indicates whether the entire target object is primary key - in that case the object can't be updated in the db, but rather deleted and then re-inserted.

protected transient DataModifyQuery updateListOrderFieldQuery

bulkUpdateListOrderFieldQuery

protected transient DataModifyQuery bulkUpdateListOrderFieldQuery

pkUpdateListOrderFieldQuery

protected transient DataModifyQuery pkUpdateListOrderFieldQuery

Method Detail

isRelationalMapping

public boolean isRelationalMapping()
INTERNAL:

Overrides:
isRelationalMapping in class DatabaseMapping

addOverrideManyToManyMapping

public void addOverrideManyToManyMapping(ManyToManyMapping mapping)
INTERNAL: In JPA users may specify overrides to apply to a many to many mapping on a shared embeddable descriptor. These settings are applied at initialize time, after the reference descriptor is cloned. In an aggregate collection case, this is not supported and currently silently ignored and does nothing.

Specified by:
addOverrideManyToManyMapping in interface EmbeddableMapping

addOverrideUnidirectionalOneToManyMapping

public void addOverrideUnidirectionalOneToManyMapping(UnidirectionalOneToManyMapping mapping)
INTERNAL: In JPA users may specify overrides to apply to a unidirectional one to many mapping on a shared embeddable descriptor. These settings are applied at initialize time, after the reference descriptor is cloned. In an aggregate collection case, this is not supported and currently silently ignored and does nothing.

Specified by:
addOverrideUnidirectionalOneToManyMapping in interface EmbeddableMapping
