This module allows to specify 'virtual columns' in DBIx::Class schema classes. Virtual columns behave almost like regular columns but are not stored in the database. They may be used to store temporary information in the DBIx::Class::Row object and without introducting an additional interface. Most DBIx::Class methods like "set_column", "set_columns", "get_column", "get_columns", "column_info", ... will work with regular as well as virtual columns.
