This example shows how to create a aggregate collection mapping and add it to a descriptor using Java code.

Aggregate Collection Mapping

public void customize(ClassDescriptor descriptor) { 
    AggregateCollectionMapping mapping = new AggregateCollectionMapping();  

    // configure mapping
    ... 

    // add mapping to descriptor
    descriptor.addMapping(mapping);
}
