org.datanucleus.store.mapped.IdentifierFactory.newIdentifier()
To be called when we want an identifier name creating based on the identifier. Creates identifier for COLUMN, FOREIGN KEY, INDEX and TABLE @param identifierType the type of identifier to be created @param identifierName The identifier name @return The DatastoreIdentifier

     * @return The BooleanExpression for a query filter in the form "collection.isEmpty()".
