Examples of org.apache.cayenne.map.Embeddable

org.apache.cayenne.map.Embeddable
A mapping descriptor of an embeddable class. Embeddable is a persistent class that doesn't have its own identity and is embedded in other persistent classes. It can be viewed as a custom type mapped to one or more database columns. Embeddable mapping can include optional default column names that can be overriden by the owning entity. @since 3.0
