org.eclipse.persistence.descriptors.ClassExtractor

Purpose: Abstract class to allow complex inheritance support. Typically class indicators are used to define inheritance in the database, however in complex cases the class type may be determined through another mechanism. The class extractor must be able to determine and return the class type from the database row. @see org.eclipse.persistence.descriptors.InheritancePolicy#setClassExtractor(ClassExtrator)

        descriptor.addMapping(isCollection);
        
        XMLField isColl = new XMLField("@isCollection");
        isColl.setSchemaType(BOOLEAN_QNAME);
        descriptor.getInheritancePolicy().setClassIndicatorField(isColl);
        descriptor.getInheritancePolicy().setClassExtractor(new ClassExtractor() {
            @Override
            public Class<?> extractClassFromRow(Record record, Session session) {
                Class<?> clz = Result.class;
