    Yeah, DbGenerator will do that:

    http://objectstyle.org/cayenne/api/cayenne/org/objectstyle/cayenne/
    access/DbGenerator.html

    Since it was created for internal purposes, API may not be all that
    friendly... But basically you need to get hold of a DataNode instance
    and get DbAdapter, DataMap, and DataSource from it. After that
    instantiate DbGenerator, call "setShould*" methods to configure what
    you (do not) want to generate... And then call "runGenerator".
