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


        // filter out excluded entities...
        Iterator<Embeddable> it = embeddables.iterator();


        while (it.hasNext()) {
            Embeddable e = it.next();


            // note that unlike entity, embeddable is matched by class name as it doesn't
            // have a symbolic name...
            if (!nameFilter.isIncluded(e.getClassName())) {
                it.remove();
            }
        }


        return embeddables;
