ODBA - persistable.rb

    # A Persistable instance can be _prefetchable_. This means that the object
    # can be loaded at startup by calling ODBA.cache.prefetch, and that it will 
    # never expire from the Cache. The prefetch status can be controlled per 
    # instance by setting the instance variable @odba_prefetch, and per class by 
    # overriding the module constant ODBA_PREFETCH

    def odba_prefetch?
      @odba_prefetch \
        || (defined?(self::class::ODBA_PREFETCH) && self::class::ODBA_PREFETCH)
