All Implemented Interfaces:

Serializable, Cloneable, EISMapping

public class EISCompositeObjectMapping
extends AbstractCompositeObjectMapping
implements EISMapping

EIS Composite Object Mappings map a Java object to a privately owned, one-to-one relationship to an EIS Record according to its descriptor's record type.

Record formats

Record Type	Description
Indexed	Ordered collection of record elements. The indexed record EIS format enables Java class attribute values to be retreived by position or index.
Mapped	Key-value map based representation of record elements. The mapped record EIS format enables Java class attribute values to be retreived by an object key.
XML	Record/Map representation of an XML DOM element.

Since:

Oracle TopLink 10g Release 2 (10.1.3)

EISCompositeObjectMapping

public EISCompositeObjectMapping()

Method Details

isEISMapping

public boolean isEISMapping()

INTERNAL:

Overrides:

isEISMapping in class DatabaseMapping

getXPath

public String getXPath()

Get the XPath String

Returns:

String the XPath String associated with this Mapping

setXPath

public void setXPath(String xpathString)

Set the Mapping field name attribute to the given XPath String

Parameters:

xpathString - String

getFieldName

public String getFieldName()

PUBLIC: Return the name of the field mapped by the mapping.

setFieldName

public void setFieldName(String fieldName)

PUBLIC: Set the name of the field mapped by the mapping.

buildCompositeRow

protected Object buildCompositeRow(Object attributeValue,
 AbstractSession session,
 AbstractRecord record,
 DatabaseMapping.WriteType writeType)

Specified by:

buildCompositeRow in class AbstractCompositeObjectMapping

buildCompositeObject

protected Object buildCompositeObject(ObjectBuilder objectBuilder,
 AbstractRecord nestedRow,
 ObjectBuildingQuery query,
 CacheKey parentCacheKey,
 JoinedAttributeManager joinManager,
 AbstractSession targetSession)

Specified by:

buildCompositeObject in class AbstractCompositeObjectMapping

writeFromObjectIntoRow

public void writeFromObjectIntoRow(Object object,
 AbstractRecord record,
 AbstractSession session,
 DatabaseMapping.WriteType writeType)
                            throws DescriptorException
