public class EISDescriptor
extends ClassDescriptor

An EISDescriptor defines the mapping from a JCA data structure to a Java object. There are two types of EIS descriptors:

• Root - indicates to the EclipseLink runtime that the EIS descriptor's reference class is a parent class: no other class will reference it by way of a composite object mapping or composite collection mapping. For an EIS root descriptor, EIS interactions can be defined to invoke methods on an EIS
• Composite - indicates to the EclipseLink runtime that the EIS descriptor's reference class may be referenced by a composite object mapping or composite collection mapping

Since:

OracleAS TopLink 10g (10.0.3)
