The CampaignDatabase class encapsulates support for interacting with the StoreCampaignObject and RetrieveCampaignObject script functions. It allows CLR code to be registered to handle specific calls to both of these script functions, via the StoreCampaignDatabaseEvent and RetrieveCampaignDatabaseEvent events, respectively. These two events allow code to either receive a serialized, GFF-format version of a game object, or to instantiate a game object from a GFF-format serialized buffer.
