IOleCache
The IOleCache interface provides control of the presentation data that gets cached inside
of an object. Cached presentation data is available to the container of the
object even when server application is not running or is unavailable.
When to Implement
The IOleCache interface can be implemented by an object handler and an in-process server.
However, you typically use or aggregate the OLE-provided implementation.
When to Use
The OLE-provided implementation creates a class node for each aspect and
format of the data that it stores. In addition to the presentation data, the class
node holds the sink pointer for the advisory connection and manages the sending
of view notifications to the advise sink.
