This section describes the various components that you must configure in order to use a relational one-to-one mapping.
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.
This table lists the configurable options for a relational one-to-one mapping.

This example shows how to create a one-to-one mapping and add it to a descriptor using Java code.
One-to-One Mapping
public void customize(ClassDescriptor descriptor) {
OneToOneMapping mapping = new OneToOneMapping();
// configure mapping
...
// add mapping to descriptor
descriptor.addMapping(mapping);
}
For more information, see the following:
For information on using JPA to configure one-to-one mappings, see @OneToOne.
