All Implemented Interfaces:

Serializable, Cloneable

Direct Known Subclasses:

AbstractCompositeCollectionMapping, AbstractCompositeObjectMapping, AggregateObjectMapping, XMLInverseReferenceMapping, XMLObjectReferenceMapping

public abstract class AggregateMapping
extends DatabaseMapping

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 if the source (parent)object exists, then the target (child or owned) object must exist. This class implements the behavior common to the aggregate object and structure mappings.

Since:

TopLink for Java 1.0

protected String referenceClassName

referenceDescriptor

protected ClassDescriptor referenceDescriptor

The descriptor of the reference class

hasNestedIdentityReference

Constructor Details

AggregateMapping

protected AggregateMapping()

Default constructor.

Method Details

buildAggregateDeleteQuery

protected DeleteObjectQuery buildAggregateDeleteQuery(DeleteObjectQuery sourceQuery,
 Object sourceAttributeValue)

Make a copy of the sourceQuery for the attribute.

buildAggregateModifyQuery

protected void buildAggregateModifyQuery(ObjectLevelModifyQuery sourceQuery,
 ObjectLevelModifyQuery aggregateQuery,
 Object sourceAttributeValue)

Initialize the aggregate query with the settings from the source query.

buildAggregateWriteQuery

protected WriteObjectQuery buildAggregateWriteQuery(WriteObjectQuery sourceQuery,
 Object sourceAttributeValue)

Make a copy of the sourceQuery for the attribute.

buildBackupClone

public void buildBackupClone(Object clone,
 Object backup,
 UnitOfWorkImpl unitOfWork)

INTERNAL: Clone the attribute from the clone and assign it to the backup.

Specified by:

buildBackupClone in class DatabaseMapping

Parameters:

clone - TODO

backup - TODO

unitOfWork - TODO

buildBackupClonePart

protected Object buildBackupClonePart(Object attributeValue,
 UnitOfWorkImpl unitOfWork)

INTERNAL: Build and return a backup clone of the attribute.

buildClone

public void buildClone(Object original,
 CacheKey cacheKey,
 Object clone,
 Integer refreshCascade,
 AbstractSession cloningSession)

INTERNAL: Clone the attribute from the original and assign it to the clone.

Specified by:

buildClone in class DatabaseMapping

Parameters:

original - TODO

cacheKey - TODO

clone - TODO

refreshCascade - TODO

buildCloneFromRow

public void buildCloneFromRow(AbstractRecord databaseRow,
 JoinedAttributeManager joinManager,
 Object clone,
 CacheKey sharedCacheKey,
 ObjectBuildingQuery sourceQuery,
 UnitOfWorkImpl unitOfWork,
 AbstractSession executionSession)

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.

Specified by:

buildCloneFromRow in class DatabaseMapping

Parameters:

databaseRow - TODO

joinManager - TODO

clone - TODO

sharedCacheKey - TODO

 AbstractSession targetSession)

INTERNAL: Merge changes from the source to the target object.
