Configuring Structure Name

Certain object-relational mappings require the specification of the data type or structure name of the field being mapped. The structure name is the name of the array or table type that defines the field.

Table 50-6 summarizes which object-relational mappings support this option.

Table 50-6 Mapping Support for Structure Name

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 the object-relational mapping method setStructureName to specify the structure of the attribute being mapped.

Example 50-4 shows how to use this method with an ObjectArrayMapping that maps the Employee class attribute phones to database field name PHONE_NUMBERS of type PHONE_ARRAY_TYPE.

Example 50-4 Configuring Structure Name in Java

ObjectArrayMapping phonesMapping = new ObjectArrayMapping();
managerMapping.setReferenceClass("Employee.class");
phonesMapping.setAttributeName("phones");
phonesMapping.setFieldName("PHONE_NUMBERS");
phonesMapping.setStructureName("PHONE_ARRAY_TYPE");
