Class DDLIndex

java.lang.Object
net.java.ao.schema.ddl.DDLIndex
public class DDLIndex extends Object
Database-agnostic reprensentation of a general field index statement (not related to full-text indexing). To save on object creation, as well as to simplify schema parsing, table and field names are stored rather than full DDL representations. This class also defines the convention imposed to generate the names of field indexes. It is important that all DDL renderers (i.e. database providers) observe this convention, else migrations will do strange things.
