37 * Data class for counting greetings
39 * We use the DB_DataObject framework for data classes in StatusNet. Each
40 * table maps to a particular data class, making it easier to manipulate
43 * Data classes should extend Memcached_DataObject, the (slightly misnamed)
44 * extension of DB_DataObject that provides caching, internationalization,
45 * and other bits of good functionality to StatusNet-specific data classes.
