public class InClassNameIndicator

extends ColumnClassIndicator

Determines the class of database records using a column holding the class name, and limits SELECTs using an IN (...) statement. This mapping initializes the possible subclasses with a SELECT DISTINCT on the class column, and thereafter assumes it has a complete list of subclasses to work with.
