abstract class Jennifer::View::Materialized

Overview

Base class for a database materialized view#Materialized_views).

The only difference from Base is one additional method .refresh which allows refreshing data of the view. Also this class usage makes sense only if you use PostgreSQL as only it has native support of materialized views.
