In a preferred embodiment, a presentation cache object provides a presentation cache with multiple cache entries. Each entry contains an indication of the format of the presentation data and the presentation data stored in that particular format. In addition, other information, such as the advisees of advisory connections for notification of cache updates, can be maintained. The presentation cache object responds to requests for retrieving source object data by returning presentation data cached within the presentation cache when it is available. In addition, the presentation cache object determines when it should delegate requests to the source object and when it can satisfy them on its own. The presentation cache object can return presentation data to a requesting client program even if the server program implementing the source object is unavailable or not running. The presentation cache object can also choose to persistently store its cache entries so that the presentation cache is maintained when the source object is closed. In addition, client programs can provide control over the frequency and subject of presentation data updates within the presentation cache.Other References
