All Implemented Interfaces:

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 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)
