Configuring Reference Class

When mapping an attribute that involves a relationship to another class, you must specify the reference class–the Java class to which the mapped attribute refers.

Table 50-3 summarizes which object-relational mappings support this option.

Table 50-3 Mapping Support for Reference Class

Mapping	Using TopLink Workbench	Using Java
Object-Relational Structure Mapping
Object-Relational Reference Mapping
Object-Relational Array Mapping
Object-Relational Object Array Mapping
Object-Relational Nested Table Mapping

Using Java

Use oracle.toplink.mappings.ForeignReferenceMapping method setReferenceClass to specify the target class of the attribute being mapped.

Example 50-1 shows how to use this method with a ReferenceMapping that maps the manager attribute of the Employee class.

Example 50-1 Configuring Reference Class in Java

ReferenceMapping managerMapping = new new ReferenceMapping();
managerMapping.setReferenceClass("Employee.class");
managerMapping.setAttributeName("manager");
