PUBLIC:

Purpose:Provide a mapping that can map a single attribute to a number of different elements in an XML Document. This will be used to map to Choices or Substitution Groups in an XML Schema

Responsibilities:

• Allow the user to specify XPath -> Type mappings
• Handle reading and writing of XML Documents containing a single choice or substitution group element

The XMLChoiceMapping allows the user to specify a number of different xpaths, and types associated with those xpaths. When any of these elements are encountered in the XML Document, they are read in as the correct type and set in the object.

Setting up XPath mappings:Unlike other OXM Mappings, instead of setting a single xpath, the addChoiceElement method is used to specify an xpath and the type associated with this xpath.
xmlChoiceCollectionMapping.addChoiceElement("mystring/text()", String.class);
xmlChoiceCollectionMapping.addChoiceElement("myaddress", Address.class);

Method Details

getConverter

public Converter getConverter()

Specified by:

getConverter in interface org.eclipse.persistence.internal.oxm.mappings.ChoiceObjectMapping<AttributeAccessor,org.eclipse.persistence.internal.sessions.AbstractSession,org.eclipse.persistence.internal.queries.ContainerPolicy,Converter,ClassDescriptor,org.eclipse.persistence.internal.helper.DatabaseField,XMLMarshaller,Session,XMLUnmarshaller,XMLField,XMLMapping,XMLRecord>

setConverter

public void setConverter(Converter converter)

Set the converter on the mapping. A converter can be used to convert between the object's value and database value of the attribute.

Specified by:

setConverter in interface org.eclipse.persistence.internal.oxm.mappings.ChoiceObjectMapping<AttributeAccessor,org.eclipse.persistence.internal.sessions.AbstractSession,org.eclipse.persistence.internal.queries.ContainerPolicy,Converter,ClassDescriptor,org.eclipse.persistence.internal.helper.DatabaseField,XMLMarshaller,Session,XMLUnmarshaller,XMLField,XMLMapping,XMLRecord>

buildBackupClone

public void buildBackupClone(Object clone,
 Object backup,
 org.eclipse.persistence.internal.sessions.UnitOfWorkImpl unitOfWork)

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

Specified by:

buildBackupClone in class DatabaseMapping

buildClone

public void buildClone(Object original,
 org.eclipse.persistence.internal.identitymaps.CacheKey cacheKey,
 Object clone,
 Integer refreshCascade,
 org.eclipse.persistence.internal.sessions.AbstractSession cloningSession)

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

Specified by:

buildCloneFromRow

public void buildCloneFromRow(org.eclipse.persistence.internal.sessions.AbstractRecord databaseRow,

 ObjectBuildingQuery sourceQuery,
 org.eclipse.persistence.internal.sessions.UnitOfWorkImpl unitOfWork,
 org.eclipse.persistence.internal.sessions.AbstractSession executionSession)

Description copied from class: DatabaseMapping

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.
