===== Row Gateways =====

:!: Prior to VuFind 4.0, each table class specifies the associated row class, so if you need to override a row class, you also need to override the table class, if only to change how it loads rows. Starting in release 4.0, the row-specific plugin manager was added to allow direct row overriding.
