Class AggregateObjectMapping

java.lang.Object
  extended by org.eclipse.persistence.mappings.DatabaseMapping
      extended by org.eclipse.persistence.mappings.AggregateMapping
          extended by org.eclipse.persistence.mappings.AggregateObjectMapping
All Implemented Interfaces:
java.io.Serializable, java.lang.Cloneable, EmbeddableMapping, MapComponentMapping, MapKeyMapping, RelationalMapping

public class AggregateObjectMapping
extends AggregateMapping
implements RelationalMapping, MapKeyMapping, EmbeddableMapping

Purpose:Two objects can be considered to be related by aggregation if there is a strict 1:1 relationship between the objects. This means that the target (child or owned) object cannot exist without the source (parent) object. In TopLink, it also means the data for the owned object is stored in the same table as the parent.

Field Detail

isNullAllowed

protected boolean isNullAllowed
If all the fields in the database row for the aggregate object are NULL, then, by default, the mapping will place a null in the appropriate source object (as opposed to an aggregate object filled with nulls). To change this behavior, set the value of this variable to false. Then the mapping will build a new instance of the aggregate object that is filled with nulls and place it in the source object.


aggregateKeyTable

protected org.eclipse.persistence.internal.helper.DatabaseTable aggregateKeyTable

aggregateToSourceFields

protected transient java.util.Map<java.lang.String,org.eclipse.persistence.internal.helper.DatabaseField> aggregateToSourceFields
322233 - changed to store the source DatabaseField to hold Case and other colunm info


nestedFieldTranslations

protected transient java.util.Map<java.lang.String,java.lang.Object[]> nestedFieldTranslations
Map of nested attributes that need to apply an override name to their a nested aggregate mapping's database field. Aggregate to source fields map is the existing EclipseLink functionality and works well when all embeddable mappings have unique database fields. This map adds specific attribute to database field override.

See Also:
addFieldTranslation()

overrideManyToManyMappings

protected transient java.util.List<ManyToManyMapping> overrideManyToManyMappings
List of many to many mapping overrides to apply at initialize time to their cloned aggregate mappings.


overrideUnidirectionalOneToManyMappings

protected transient java.util.List<UnidirectionalOneToManyMapping> overrideUnidirectionalOneToManyMappings
List of unidirectional one to many mapping overrides to apply at initialize time to their cloned aggregate mappings.


mapsIdMappings

protected transient java.util.List<DatabaseMapping> mapsIdMappings
List of maps id mappings that need to be set to read only at initialize time on their cloned aggregate mappings.

public void addAdditionalFieldsToQuery(ReadQuery selectionQuery,
                                       Expression baseExpression)
INTERNAL: Used when initializing queries for mappings that use a Map Called when the selection query is being initialized to add the fields for the map key to the query

Specified by:
addAdditionalFieldsToQuery in interface MapKeyMapping

addFieldsForMapKey

public void addFieldsForMapKey(org.eclipse.persistence.internal.sessions.AbstractRecord joinRow)
INTERNAL: Used when initializing queries for mappings that use a Map Called when the insert query is being initialized to ensure the fields for the map key are in the insert query

Specified by:
addFieldsForMapKey in interface MapKeyMapping

addFieldNameTranslation

public void addFieldNameTranslation(java.lang.String sourceFieldName,
                                    java.lang.String aggregateFieldName)
PUBLIC: Add a field name translation that maps from a field name in the source table to a field name in the aggregate descriptor.

public void addFieldTranslation(org.eclipse.persistence.internal.helper.DatabaseField sourceField,
                                java.lang.String aggregateFieldName)
PUBLIC: Add a field translation that maps from a field in the source table to a field name in the aggregate descriptor.

Specified by:
addFieldTranslation in interface EmbeddableMapping

addMapsIdMapping

public void addMapsIdMapping(DatabaseMapping mapping)
INTERNAL: In JPA users may specify a maps id mapping on a shared embeddable descriptor. These mappings need to be set to read-only at initialize time, after the reference descriptor is cloned.


addNestedFieldTranslation

public void addNestedFieldTranslation(java.lang.String attributeName,
                                      org.eclipse.persistence.internal.helper.DatabaseField sourceField,
                                      java.lang.String aggregateFieldName)
INTERNAL: Add a nested field translation that maps from a field in the source table to a field name in a nested aggregate descriptor.

allAggregateFieldsAreNull

protected boolean allAggregateFieldsAreNull(org.eclipse.persistence.internal.sessions.AbstractRecord databaseRow)
INTERNAL: Return whether all the aggregate fields in the specified row are NULL.


allowNull

public void allowNull()
PUBLIC: If all the fields in the database row for the aggregate object are NULL, then, by default, the mapping will place a null in the appropriate source object (as opposed to an aggregate object filled with nulls). This behavior can be explicitly set by calling #allowNull(). To change this behavior, call #dontAllowNull(). Then the mapping will build a new instance of the aggregate object that is filled with nulls and place it in the source object. In either situation, when writing, the mapping will place a NULL in all the fields in the database row for the aggregate object. Note: Any aggregate that has a relationship mapping automatically does not allow null.


backupAttributeValueIsNull

INTERNAL: Return whether the query's backup object has an attribute value of null.

INTERNAL: A combination of readFromRowIntoObject and buildClone.

buildClone assumes the attribute value exists on the original and can simply be copied.

readFromRowIntoObject assumes that one is building an original.

Both of the above assumptions are false in this method, and actually attempts to do both at the same time.

Extract value from the row and set the attribute to this value in the working copy clone. In order to bypass the shared cache when in transaction a UnitOfWork must be able to populate working copies directly from the row.

dontAllowNull

public void dontAllowNull()
