Configuring a Relational Aggregate Collection Mapping (ELUG)
This section describes the various components that you must configure in order to use a relational aggregate collection mapping.
|
Note: To use a relational aggregate collection mapping with Workbench, you must use an amendment method (see Configuring Amendment Methods). |
For information on how to configure EclipseLink mappings options common to two or more mapping types, see Configuring a Mapping.
For information on how to create EclipseLink mappings, see Creating a Mapping.
Configurable Options for Relational Aggregate Collection Mapping lists the configurable options for a relational aggregate collection mapping.

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);
}
