public class StructureMapping extends AbstractCompositeObjectMapping
Purpose: A structure is an object-relational user-defined data-type or object-type. A structure is similar to a Java class as it defines attributes or fields where each attribute is either a primitive data-type, another structure, an array, or a reference to another structure. The mapping is similar to an AggregateObjectMapping, as multiple objects are stored in a single table.
