    Support for embeddable classes
    ------------------------------

                     Key: CAY-733
                     URL: https://issues.apache.org/cayenne/browse/CAY-733
                 Project: Cayenne
              Issue Type: New Feature
              Components: Cayenne Core Library
        Affects Versions: 3.0
                Reporter: Andrus Adamchik
             Assigned To: Andrus Adamchik
                 Fix For: 3.0

    JPA specification supports a notion of "embeddable" class. Embeddable classes can be viewed as multi-column custom types that do not have their own identity and belong to another persistent object. Entities that embed them can override DB column mapping. Currently Cayenne supports single-column custom types via ExtendedType mechanism. We need to expand that to support multi-column Embeddables and mapping via the Modeler.

    This is a master task for Embeddable implementation in Cayenne. Specific coding tasks will be tracked via separate linked jira issues.
