public class XMLAnyAttributeMapping
extends DatabaseMapping
implements XMLMapping, AnyAttributeMapping<AbstractSession,AttributeAccessor,ContainerPolicy,ClassDescriptor,DatabaseField,XMLRecord>

Purpose:The XMLAnyAttributeMapping is used to map to an attribute in an object to any xml attributes contained on a specific element in the XML Document. The attribute in the object will contain a map of attribute values keyed on QName. In the case that one or more of the attributes found on the specified element is already mapped to another attribute in the object, that attribute will be ignored during the unmarshal operation.

Setting the XPath: TopLink XML mappings make use of XPath statements to find the relevant data in an XML document. The XPath statement is relative to the context node specified in the descriptor. The XPath may contain node type, path, and positional information. The XPath is specified on the mapping using the setXPath method. Note that for XML Any Attribute Mappings the XPath is optional. Not setting the xpath, will cause the mapping to look for any attribute children directly owned by the current Element.

Method Details

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

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

cloningSession - TODO

buildCloneFromRow

public void buildCloneFromRow(AbstractRecord Record,
 JoinedAttributeManager joinManager,
 Object clone,
 CacheKey sharedCacheKey,
 ObjectBuildingQuery sourceQuery,
 UnitOfWorkImpl unitOfWork,
 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.

Specified by:

buildCloneFromRow in class DatabaseMapping

Parameters:

Record - TODO

joinManager - TODO

clone - TODO

sharedCacheKey - TODO

sourceQuery - TODO

unitOfWork - TODO

executionSession - TODO
