EIS Composite Collection Mapping

An EIS composite collection mapping maps a collection of Java objects to a privately owned one-to-many relationship in an EIS record according to its descriptor's record type as shown in Table 56-5. Composite collection mappings can reference any class that has a TopLink descriptor.

Table 56-5 EIS Composite Collection Mapping by EIS Record Type

EIS Record Type	Mapping Behavior
Indexed	Maps directly to a subrecord in the indexed recordFoot 1 .
Mapped	Maps directly to a subrecord in the mapped recordFootref 1.
XML	Maps directly to an attribute or text node in the XML recordFoot 2 .

Figure 56-7 illustrates a composite collection EIS mapping between Phone class attribute phoneNumbers and an XML record. Employee attribute phoneNumbers is mapped to an XML record composed of an EMPLOYEE element that contains a sequence of PHONE_NUMBER elements.
