## org.apache.cayenne.map
Class Embeddable

    java.lang.Object
      org.apache.cayenne.map.Embeddable

All Implemented Interfaces:
  Serializable, XMLSerializable

    public class Embeddable

extends Object
implements XMLSerializable, Serializable

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.
